• Pin 2: Common (Ground)

• Pin 3: + Output Signal

Operating Principle

This unit uses a piezoresistive sensor element. As pressure changes against the internal diaphragm, the sensor generates a proportional electrical output that varies with the supply voltage. Because it is ratiometric, the output magnitude scales with the input voltage, which simplifies interfacing with ratiometric ADCs in controllers and PLCs.

Typical Applications

• Commercial refrigeration pressure monitoring

• HVAC control systems

• Industrial process systems

• Electronic controllers and data acquisition inputs

Its sealed gauge design makes it suitable for refrigerants and closed-loop fluid systems.

Installation Notes

• Install in a location free from excessive vibration and mechanical shock.

• Ensure correct orientation of pressure and electrical connections per installation guidance.

• Use appropriate thread sealing and torque values for the UNF 7/16-20 connection.

Packaging & Handling

• Supplied in protective packaging to prevent physical damage during transport.

• Handle with care — do not expose the diaphragm to sharp impact or corrosive media.
