Model K2 Pressure Transducer

Brand: Ashcroft Inc
Does not ship to Virginia, United States

The K2 is similar to the K1 Series except offering mV/V output options.

The K2 is a proven and versatile pressure transducer 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 transducers are offered in many standard pressure ranges with high-quality millivolt output signal ratiometric to supply voltage.

Transducer performance is directly traceable to the National Institute of Standards and Technology. A calibration test certificate is available with each transducer.
