PSQ is a low-cost gauge pressure transducer manufactured by COMECO. It is based on thin-film resistive sensor elements and an electronic block providing temperature compensation and generating a 2-wire current output signal. When operating at process temperatures between 10 °С and 40 °С, the transmitter achieves an accuracy better than 1%. All the wetted parts are made of stainless steel and the robust design guarantees good vibration and shock resistance as well as normal operation at medium temperatures up to 135 °С. All of the above make the PSQ pressure transmitter well suitable in all applications where robustness, compact sizes, and low budget are of higher importance.
