BENTLY NEVADA 330904-00-09-10-02-05 8mm eddy current pre-filter

Product Description

Bently Nevada 330904-00-09-10-02-05 is the 3300 XL NSv 8mm Proximitor Sensor, the core unit of Bently Nevada (Baker Hughes) non-contact eddy-current transducer system, compliant with API 670. It supplies excitation power to the probe, processes the sensed signal and outputs continuous voltage proportional to shaft gap for shaft vibration, axial displacement and differential expansion measurement. It provides cable break/short and power fault diagnostics with strong RFI immunity. DIN rail or panel mount compatible, commonly paired with 3500 machinery protection rack for turbine and compressor protection.
