Electric Pressure Sender


Stainless Steel 316L Diaphragm

Linear voltage output






    Shaoxing Huazhen's electrical pressure transducer 3313-EPT is specifically designed for pressure measurements lower than 150PSI. 3313-EPT uses brass housing and stainless steel diaphragm withstanding exposure to compatible liquid & gaseous media. Excited by DC5V, the transducer provides a DC0.5 to 4.5 V linear signal output proportional to pressure. Typical applications include spraying equipment, test apparatus, automotive, marine, refrigeration and hydraulic systems, gas tank pressure monitoring, level measurement etc.
