The Ashcroft K1 is a proven and versatile pressure transducer/transmitter incorporating polysilicon thin film technology. Modern low-pressure chemical vapor deposition methods provide simple, stable molecular bonds between the metal diaphragm and a polysilicon strain gage bridge. There are no epoxies or bonding agents to contribute to signal instability or drift. The integral metal diaphragm and polysilicon bridge are virtually unaffected by shock, vibration or mounting. These transmitters are offered in many standard pressure ranges with either current or voltage output signals. Transmitter performance is directly traceable to the NationaI Institute of Standards and Technology. A calibration test certificate is available with each transmitter.
