K1 Pressure Transducer
Brand: Ashcroft Inc
Does not ship to OH, United States
The Ashcroft® K1 is a proven and versatile pressure transducer/transmitter.
Ashcroft’s thin film sensor technology and production processes eliminate signal instability and drift; making the K1 virtually unaffected by shock or vibration.
A perfect choice for harsh operating environments.
