PSM-AB
Ultra-Small Sized Pressure Transducers with Strong Fluorocarbon Resin Cable
PSM-AB series is the smallest pressure sensor in Kyowa products designed based on integration of sensor element and diaphragm. This sensor adopts quarter bridge 3-wire system and configures a full bridge in a bridge adaptor. In addition, this sensor is installed by adhesives. Developed mainly for gas pressure measurement, PSM-AB series can measure more transducers.

Note
(1) Copper alloy is used for sensing element. Avoid measuing corresive liquids or gases.
(2) The mainframe has been assembled using an epoxy adhesive. Do not therefore use the transducer to measure organic solvent. (eg. Toluene, ketone and others)
