The Ashcroft K1 industrial pressure transducer is a proven and versatile pressure transducer/transmitter that incorporates polysilicon thin film technology. Modern low-pressure chemical vapor deposition methods provide simple, stable molecular bonds between the metal diaphragm and a polysilicon strain gauge bridge. There are no epoxies or bonding agents to contribute to signal instability or drift.

The integral metal diaphragm and polysilicon bridge in the Ashcroft K1 are virtually unaffected by shock, vibration, or mounting. These transmitters are available in pressure ranges from vacuum to 20,000 psi with either current or voltage output signals. Transmitter performance is directly traceable to the National Institute of Standards and Technology. A calibration test certificate is available with each transmitter.
