BENTLY NEVADA 330500-01-01 Velomitor Piezo-Velocity Sensor
Product Description
330500-01-01 is part of the Bently Nevada (Baker Hughes) 330500 Velomitor family. It is an integrated piezo-velocity sensor with built-in integrating circuitry, directly outputting vibration velocity signal. Solid-state construction without moving parts. The housing is made of 316L stainless steel, fitted with a 2-pin hermetically sealed military-style connector. It can be mounted in any orientation to measure absolute vibration of bearing housings and machine casings for rotating machinery condition monitoring and protection. It supports long cable runs and hazardous area approvals for predictive maintenance of critical industrial assets. Suffix code definition: 01 = 1/2-20 UNF mounting thread; 01 = hazardous area approval version.
