Bently Nevada 330881-28-00-265-00-02 Proximity Sensor

Product Description

Bently Nevada (Baker Hughes) 330881-28-00-265-00-02 is an armored 3300 XL 11 mm eddy-current proximity probe, the sensing front end of TSI turbine supervision systems. It works with extension cable and Proximitor to measure shaft vibration, thrust position, differential expansion and keyphasor signals non-invasively, compliant with API 670. The 11 mm probe has stainless steel housing, PPS tip and armored cable for mechanical protection against crush and abrasion, designed for oil-laden, high-temperature rotating machinery such as steam turbines and compressors.
