CA901 144-901-000-282 Piezoelectric Accelerometer

DESCEIPTION:

The use of VC2 type single crystal material in the CA 901 compression mode accelerometer provides an extremely stable instrument.
The transducer is designed for long-term monitoring or development testing. It is fitted with an integral mineral insulated cable (twin conductors) which is terminated with a Lemo or a high-temperature connector from Vibro-Meter.
