Series 645 Wet/Wet Differential Pressure Transmitter

Description: The Series 645 Wet/Wet Differential Pressure Transmitter is engineered for compatibility with any gas or liquid that is suitable for use with materials such as 17-4 PH stainless steel, 300 Series stainless steel, Viton, and Silicone O-rings. This transmitter excels in accurately measuring differential pressure even when both ports are exposed to liquid. It features a fast response capacitance sensor and a unique isolation system.

The isolation system effectively transmits the motion of the differential pressure sensing diaphragm from the high line pressure environment to the dry enclosure, where it proportionally moves one of a pair of capacitance plates. The variable capacitance is then converted into a current proportional to the differential pressure by the capacitance sensing and signal conditioning circuit housed in the enclosure. Additionally, the electronic circuit linearizes output versus pressure, standardizes the output, and compensates for thermal effects of the sensor.

Specifications:

  • Service: Compatible gases or liquids applied to both pressure and reference ports.
  • Output: 4 to 20 mA, two-wire.
  • Supply Voltage: 11 to 30 VDC.
