cd PTX 500 SERIES Industrial Pressure Transmitters • Hastelloy and stainless steel wetted parts • Absolute and gauge configurations • DIN pressure ranges or custom scaled • Electrical and pressure connection options • Intrinsically safe units available • Low cost The PTX 500 series combines micro machined silicon diaphragms with fully welded stainless steel and Hastelloy pressure ports to provide a highly accurate, stable pressure transmitter with the materials and environmental protection required for industrial applications. The silicon sensors incorporate developments derived from aerospace applications to improve output noise, non-linearity and hysteresis and long term stability. Batch manufacturing ensures optimum pricing, with the ability to custom calibrate to alternate ranges and pressure units prior to completion with the required electrical connection and rapid despatch. Detachable electrical connectors (not available on submersible units) provide access to the independent zero and span trim controls, and if a configuration change to the electrical or pressure connections are required on-site replacement parts and screw in pressure adaptors are available. Each transmitter incorporates RFI/EMC and electrical spike protection, and Intrinsically Safe approved units are available as an option. 1 PTX 500 SERIES - 1/99 STANDARD SPECIFICATION Operating Pressure Range Any pressure unit and (zero based) span Output Current Electrical Connection available between 250mbar and 700 bar full 4-20mA ( two-wire configuration) Versions available for IP50 to IP68 ratings scale to gauge and absolute formats: spans (see ordering information). proportional for zero to full scale pressure. down to 100mbar available in gauge format Mating parts supplied with plug/socket only.
