The Bently Nevada 330505-02-02-02 Low Frequency Velocity Sensor is specifically designed for hydroelectric turbines where slow rotating speeds require detecting a low signal to noise ratio. It detects vibration of the stator core, stator frame, and bearing housing supports. The sensor provides early warning of pending machinery problems and helps diagnose issues before they become serious.
The sensor measures absolute vibration within the 0.5Hz to 1.0kHz range. Its two-wire design uses moving-coil technology and embedded signal conditioning circuitry to provide a voltage output directly proportional to the vibration velocity.
Stator core and stator frame vibration can cause fretting and damage to winding insulation. Mount a 330505-02-02-02 sensor on the outer diameter of the stator core and frame to detect these problems. Bearing housing vibration can distort levels of vibration measured by shaft-observing proximity probes. Placing sensors on the bearing housing measures both shaft-relative and bearing-absolute vibration signals.
The transducer connects to the 3500/46M Hydro Monitor, meeting the requirements of ISO Standard 10816-5 for mechanical vibration on non-rotating parts in hydraulic power and pumping plants.
