Product Description
Bently Nevada 370300-01 is an isolated constant-current piezoaccelerometer designed by Baker Hughes Bently Nevada for casing vibration monitoring of rotating machinery. It provides high electrical isolation between the transducer base and internal electronics, with dielectric withstand voltage up to 6000 Vdc and 5000 Vac, protecting against arcing and electrostatic discharge (ESD). The suffix -01 denotes M8×1.25 mounting thread. It has a nominal sensitivity of 100 mV/g and can work with Bently Nevada 3500 machinery protection system to capture vibration signals from bearing housings and machine casings for condition monitoring, fault diagnostics and machinery protection, delivering reliable long-term performance in harsh industrial environments.
