A fast-response capacitance sensor and signal conditioned electronic circuitry provide a highly accurate, linear analog output proportional to pressure. Both unidirectional and bi-directional pressure ranges are available for applications with line pressure up to 250 psig.
A unique isolation system transmits the motion of the differential pressure sensing diaphragm from the high line pressure environment (e.g. corrosive liquids) to the dry (air) enclosure where it moves one of a pair of capacitance plates proportionally to the diaphragm movement. This system responds to pressure changes approximately 20 times faster than conventional fluid-filled transducers.
The variable capacitance is converted to an electrical output proportional to the differential pressure by the capacitance-sensing and signal conditioning circuit located in the enclosure. The electronic circuit linearizes output vs. pressure and compensates for thermal effects of the sensor.

Zero and span adjustment pots are located on the side and are used to set the pressure range.

Setra's Model 327 Micro-Display is designed for use in high density modular block gas sticks and panels required for today's 300mm tools. With a footprint of 1-1/3", the Model 327 is ideal for in-line installation between the power supply and the pressure transducer.
The 327 is a low-power consumption device, which is calibrated to convert the transducer's 0-5 VDC, 0 to 10 VDC, or 4-20 mA output to a viewable 3-1/2" digit display. The back-lit Liquid Crystal Display - LCD makes reading the display even easier.
The front face of the 327 rotates 360 degrees for viewing in any of four orientations. Front access to the multi-turn zero and span potentiometers, switchable PSI and kPa pressure units, and pressure ranges from 10 PSI to 200 PSI full scale complete this unique design.
