DYNISCO MODEL 1290 Strain Gage Input, 1/8 DIN Digital Pressure Indicator Description The model 1290 indicator offers a field scalable display and dual, configurable alarms to meet your changing pressure indication requirements. The available optically isolated mA/Vdc linear retransmission enables the user to log process trends, a valuable feature for SPC and SQC. A simple front panel instrument calibration and compact profile make the model 1290 the ideal indicator for your process. Features Benefits • 350 Ohm strain gage input • Direct pressure readings • Pushbutton programming and calibration • Easy to use • Scalable, voltage or current outputs • Send information to a variety of devices • Serial communication option • Send and receive information from PLCs, PCs, etc. • Peak and valley detection • Recall extremes of the process • Convenient 1/8 DIN size • Save panel space Specifications Performance Characteristics Instrument type: Microprocessor - based indicating panel meter Front panel: IP65/NEMA4 rated, dust/splash - proof Display: Five LED digits 0.5" (13.2 mm) high; Two red LEDs Accuracy: ±0.1% of full scale, ±1 digit at 25°C for alarm indication; One red LED for local/remote indication Normal mode rejection ratio: 60 dB at 50/60 Hz Terminations: Screw terminals on rear with safety cover Sampling time: 100 ms typical Dimensions: 1/8 DIN, 1.89" H x 3.78" W x 5.67" D Operating temperature range: 32˚F to 125°F (0˚C - 50°C) (48 mm H x 96 mm W by 144 mm D) Weight: 1 lb.
