Pressure Transducers

Learn about Pressure Transducers

A pressure transducer converts an applied pressure into an electrical analog output signal that is both linear and proportional to the applied pressure to the transducer. Pressure sensor, pressure transducer, and pressure transmitter are commonly referred to as just pressure transducers. The output electrical signal from a pressure transducer is sent to computers, PLC's, chart recorders, digital panel meters or other devices that interpret this signal and use it to display, record, and/or change the pressure in the system being monitored.

Although, technically a pressure transmitter and a pressure transducer are different, many users refer to each type interchangeably and we often do the same here at Valworx. Both convert an applied pressure into an electrical signal. This signal is sent to computers, PLC's, chart recorders, digital panel meters or other devices that interpret this signal and use it to display, record, and/or change the pressure in the system being monitored.

Pressure Transducer Types

General purpose transducers provide excellent performance, reliability and value for a wide variety of electronic pressure measurement applications. Typically the accuracy is less than or equal to 0.5% of span. These pressure transducers are available in pressure ranges up to 10,000 PSIG with 4-20mA or 0-10VDC outputs.


Industrial pressure transducers are precision engineered to fit the majority of industrial pressure measurement applications. Wika industrial transducers feature an enhanced accuracy of 0.25% of span or better. The industrial grade pressure transmitter includes zero and span adjustment for recalibration. Circuit boards use surface mount technology and are potted in silicone gel for protection against vibration, shock, and humidity.

The Wika industrial NEMA 4X pressure transducer is designed for extremely harsh, washdown, and corrosion resistant industrial pressure measurement applications. State of the art surface mount technology ensures that the unit is protected against vibration, shock and humidity. The compact design features all stainless steel construction and accuracy of 0.25% of span.


Explosion proof pressure transmitters are specifically designed to operate in hazardous environments. Most Wika explosion proof transducers meet FM and CSA agency approvals.
