C ASHCROFT' Trust the shield.™ Model KM15 Pressure Transducer Upgraded replacement to KM10 APPLICATIONS An upgraded replacement to the popular Type KM 10, the cost effective construction of the KM15 is ideally suited to address the demanding pressure sensing needs of the original equipment manufacturer in a multitude of applications, including: • Off-Road Equipment • Construction Machinery • HVAC/Refrigeration • Compressor Control • Pump Monitoring • Agricultural Implements • Diagnostic Kits • Engine Monitoring • Process Automation & Control • Hydraulic & Pneumatic Sensing • Machine Tool • RoHS compliant The Ashcroft® KM15 pressure transducer marries a proven polysilicon thin film sensor to a high performance ASIC to provide a highly accurate, stable and durable transducer. Calibration, by digital compensation, results in an extremely linear and repeatable instrument over a wide temperature range. The highly stable thin film sensor of 17-4 PH stainless steel is electron beam welded to one of a wide selection of stainless steel pressure fittings to provide superior media compatibility and overpressure capability.
