The P321 series of Wet Wet Differential Pressure Sensors use a 5 Vdc input to measure the differential pressure between two pressure ports, providing a 0.5 to 4.5 Vdc output proportional to pressure.

Incorporating an oil-filled capacitive sense element, these pressure transducers are able to withstand vacuum (negative) pressures as well as high common mode pressures. The large diaphragm protects these sensors from the accumulation of soot and other harsh materials.

Packaged in Ultem 2000 Series Plastic and using a carbon steel metal bracket as its mounting feature, the P321 pressure sensor is rugged and durable by design. This pressure transducer is temperature compensated to meet the accuracy requirements of the customer, and is rated to perform continuously at temperatures up to 125°C.

Specifically intended to withstand high common mode pressures, high vibration environments, and with its resistance to soot and other acidic media, the P321 pressure sensor delivers the optimal solution without compromising performance or reliability.
