Solid-state construction, hermetically-sealed line monitoring housings, and laser-welded flush diaphragms provide undistorted high frequency response, ruggedness and Fluid borne noise durability, even in adverse environmental conditions. The result is a quality sensor that offers a repeatable, linear, low impedance voltage output making the sensor suitable Pulsations, surges, water hammer, for measurements in a variety of gaseous, fluid, and oil switching transients, cavitation environments. 1 1 Operating from a low-cost constant-current signal conditioner, ICP sensors provide a clean, high-voltage, low-impedance linear output over a very wide operating range. They drive long, inexpensive, ordinary coaxial cables in field or factory environments without signal degradation. ICP sensors are supplied with hardware and seals for mounting. For convenience in mounting pressure probes, standard and special thread adaptors can be supplied to match specific nonstandard mounting ports (see Mounting Adaptors, page 58). To allow the user to take advantage of the wide dynamic range capability, many ICP sensors are supplied with two linear calibrations, one at full scale and one 10% of full scale. This means, for example, model 111A24, 5 mV/psi sensor may be used for accurate measurements ranging from 0 to 1000 psi or 0 to 100 psi, or anywhere in between. In fact, a user can measure 1 psi fluctuations at any static level up to 10 000 psi. Large overange capabilities are possible because a pressure sensor's diaphragm is backed by a rigid column of quartz.

Typical applications include measurement of shock and blast waves; combustion, detonation and explosions in closed bombs; projectile Projectile and time of arrival velocity; free field and underwater explosive testing; and squib lot acceptance testing. All of these applications require high frequency response and durability; ability to Underwater blast drive long cables and operate in adverse environments may also be important. For those involved in explosive blast applications, “Soroka’s Air Blast Tables” compile free-air incident and reflected blast data from Bare Spherical Pentotlite; this information is available from PCB. 13 13 In applications involving long input cables, care must be exercised to assure the measurement system has adequate frequency response. Capacitance associated with the long cables can act as a low pass filter. Sensor output voltage, cable capacitance and constant current are factors to be considered. More current is required to drive higher voltages over longer cables. Selecting a sensor to provide about 1 V full scale for the expected pressure to be measured, rather than 5V, will provide 5 times greater frequency response for a given current and cable length. PCB signal conditioners can be adjusted up to 20 mA to drive long cables. Most of the sensors listed in this section incorporate acceleration-compensating sensing elements with integral electronics, which provide a frequency-tailored, non- resonant response. Frequency tailored sensors have microsecond rise time and suppressed resonance to faithfully follow shock wave events without the characteristic “ringing” common in other sensors. See typical test results on page v, “Microsecond Shockwave Non-Resonant Response.” The cable driving nomograph listed on pages 82 and 83 will help determine the Voltage/Cable Length/Constant Current requirements and provide information on testing long cables.

Explosives testing Out of this cooperative effort, the highly successful PCB series patented 117B Conformal Ballistic Sensor was developed. In this tradition, PCB offers a complete line of Closed bombs sensors for conformal and case mouth measurements. The 117 Series conformal sensor measures true gun Recoil mechanisms chamber pressure directly through an unmodified shell case. Since the sensor diaphragm is machined to conform flush with the specific chamber diameter, the measurement Ultra high-frequency process is not altered or changed in any way. There are no cartridges to be drilled or troublesome gas passages to detonation be cleaned when using the conformal method. Conformal sensors have proven to be rugged, stable instruments, lasting hundreds of thousands of rounds. Since the same 25 25 sensor may outlast the life of many barrels, it is possible to start and finish ammunition batch qualification testing without experiencing sensor failure during the test. Our 118 Series with a ceramic coated integral diaphragm has been upgraded with an even more stable, linear sensing element. This series features a floating clamp nut that reduces strain sensitivity on the sensor body due to mounting torque. The 119 Series is an acceleration compensated version of the 118 Series. The 108 and 109 ® Series are upgraded ICP versions of the 118 and 119’s. The integral electronics in the 109 Series are shock protected, for use in high shock applications. PCB introduces the new high performance 165 Series which features an improved design for more stable, reliable measurements. Our new 165 Series was designed to retrofit popular existing mounting port styles. The new series contains a variety of models for different pressure ranges, mounting and sealing requirements. PCB also offers a high pressure static calibrator Model 905C and a high pressure dynamic calibrator Model 913A10. Side-by-side dynamic/static comparison calibration services are offered for PCB’s and competitors’ ballistic sensors.

Both seals are supplied with each sensor. T Th he e 1 16 65 5A A0 05 5 Ballistic Sensor is manufactured to retrofit weapons which have the conical end seal mounting port. The 165A05 incorporates a specially designed integral diaphragm that reduces thermal output due to transient M Mo od de ell 1 16 65 5A A0 05 5 temperature effects.

(National Institute of Standards & Technology). All instrumentation and reference standards used in the calibration process are traceable to NIST. Both static and dynamic methods are used in the calibration process. Special hydraulic and pneumatic impulse and step pressure generators, developed for in-house calibration of PCB sensors, are offered as standard commercial products. PCB also offers NIST traceable calibration services for other commercial piezoelectric sensors from acoustic levels to greater than 100 000 psi. Calibration services include shock tube amplitude/frequency response testing with microsecond step function pressures. Our new high pressure impulse calibrator, Model 913A10, allows for dynamic versus static response comparison of pressures to 100 000 psi. 49 49 Calibration data supplied by various sensor manufacturers may differ considerably. Some manufacturers may provide sensor sensitivity only at specific data points which makes non-linearity less obvious. PCB provides linearity graphs with sensitivity at specific data points. It is a recommended practice to request a copy of the calibration certificate before you purchase so you will be aware of the data being supplied. See page 56 for a copy of a typical calibration certificate.

The Model 913A10 utilizes a rugged, ® stable, and repeatable PCB quartz shear ICP accelerometer to accurately determine pressure. This unit features a 42-inch high drop-test fixture with a 53- pound tungsten mass. The mass is lifted and released by a pneumatically controlled carriage and piston. The pneumatic control panel features two safety palm buttons for releasing the drop weight. A free-falling known mass is dropped onto a piston, creating a hydraulic pressure pulse in the pressure calibration cell. The accelerometer measures the deceleration of the free-falling mass after it strikes the piston. The deceleration of the mass/piston, coupled with the geometries of the piston and cylinder, determine the pressure. This method eliminates the need for complicated drop-mass velocity measurements or uncertainties from referencing another pressure sensor. 54 54 The supplied pressure calibration cell, consisting of a precision-machined piston/manifold, is ported for two PCB Series 118/119 Ballistic Pressure Sensors. Various models of high-pressure sensors may be calibrated by interchanging the available drop-in pressure calibration cells.

However, even though the electrical insulation resistance is quite large, the charge eventually leaks to zero. The rate at which the charge leaks back to zero is dependent on the electrical insulation resistance. 77 77 In a charge mode pressure sensor used with a voltage amplifier, the leakage rate is fixed by values of capacitance and resistance in the sensor, by low-noise cable, and by the external source follower voltage amplifier used. In the case of a charge mode pressure sensor used with a charge amplifier, the leakage rate is fixed by the electrical feedback resistor and capacitor in the charge amplifier. In a pressure sensor with built-in ICP electronics, the resistance and capacitance of the crystal and the built-in ICP electronics normally determine the leakage rate. D DIIS SC CH HA AR RG GE E T TIIM ME E C CO ON NS ST TA AN NT T ((D DT TC C)) When leakage of a charge (or voltage) occurs in a Figure 5.

The value of the electrical capacitance of the system (in farads) multiplied by the P PO OL LA AR RIIT TY Y value of the electrical resistance (in ohms) is called the Discharge Time Constant (in seconds). When a positive pressure is applied to an ICP pressure sensor, the sensor yields a positive voltage. The polarity of DTC is defined as the time required for a sensor or measuring system to discharge its signal to 37% of the PCB charge mode pressure sensors is just the opposite: when a positive pressure is applied, the sensor yields a original value from a step change of measure. The DTC of a system relates to the low-frequency monitoring negative output. Charge output sensors are usually used with external charge amplifiers that invert the signal. capabilities of a system. A long discharge time constant is useful because it allows quasi-static operation during Therefore, the resulting system output polarity of a charge output sensor used with a charge amplifier will produce an calibration or measurement of certain long-duration pressure pulses. output that is the same as an ICP sensor.

When heat strikes the diaphragm of a piezoelectric pressure sensor that has crystals contained in an outer housing, the heat can cause an expansion of the case surrounding the internal crystals. Although quartz crystals are not significantly sensitive to thermal shock, the case expansion causes a lessening of the preload force on the crystals, usually causing a negative- signal output. To minimize this effect, various methods are used. Certain PCB quartz pressure sensors feature internal thermal isolation designs to minimize the effects of thermal shock. Some feature baffled diaphragms. Other models designed for maximizing the frequency response may require thermal protection coating, recess mounting, or a combination to lessen the effects of thermal shock. Examples of coatings include silicone grease, which may also be used to fill a recess mounting hole, RTV silicone rubber, vinyl electrical tape, and ceramic coatings. The RTV and tape are used as ablatives, while the ceramic coating is also used to protect some diaphragms from corrosive gasses and particle impingements. 81 81 Crystals other than quartz are used in some PCB sensors. Though sensitive to thermal shock, tourmaline is used for shock tube and underwater blast sensors. In shock tube measurements, the duration of the pressure measurement is usually so short that a layer of vinyl tape is sufficient to delay the thermal effects for the duration of the measurement. In underwater blast applications, heat transfer through the water is not significant. Note that thermal shock effects do not relate to the pressure sensor specification called “temperature coefficient” used in this catalog. The temperature coefficient specification refers to the change in sensitivity of the sensor relative to the static temperature of the sensor. Unfortunately, since the thermal shock effects cannot be easily quantified, they must be anticipated and minimized by one of the above mentioned techniques in order to ensure better measurement data.
