A pneumatic pressure sensor is designed to measure compressed air or gas pressure within a system, allowing readings to be monitored and displayed through various electronic devices.
These sensors function as transducers, converting pressure into a corresponding electrical signal. When pressure levels rise or fall outside the expected range, the sensor enables timely adjustments or alerts for further investigation.
In some cases, pressure sensors also act as pressure switches, activating or deactivating a system when the pressure reaches a predetermined threshold.
Accurate pressure monitoring is essential across numerous industries—including automotive, medical, industrial, and building systems—where sensor reliability directly impacts performance, safety, and cost efficiency. By ensuring stable system operation, these sensors help protect equipment and users while also contributing to reduced operational expenses.
The SMC PSE560 series pneumatic pressure sensor has proof pressure of 1.5 Map and is suitable for liquid or gas medium. Its supply voltage ranging between 12VDC to 24VDC and its port size is R 1/4 with M5 female thread.

The SMC PSE530 series of remote pressure sensors with a 1 to 5V analog signal output. It is for a standard pneumatic system's pressure range, while the 532 model is for low pressure. The sensors measure pressure of any non-corrosive, non-flammable gas. An accuracy of ±2% of the full scale rated pressure range is suitable for general purpose applications. The cable is molded into the sensor head and is not replaceable.

Compact Pneumatic Pressure Sensor
Series PSE digital pressure switches allow pressure to be controlled from a remote location. The PSE100 series controller has an easy to read, large, 4-digit LED display. Display units can be easily selected and changed. Series PSE510 is compact and lightweight, allowing the sensor to be mounted where needed. The use of stainless steel for all wetted parts (SUS630 for diaphragm, SUS304 for fitting) allows the PSE520 pressure sensor to be used in a wide variety of gas and fluid applications.
PSE series remote pressure and vacuum sensors have been expanded to include easy-to-use econ connectors from 3M or AMP.
