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 trans-
ducer 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 over-
pressure capability.
