BENTLY 330780-91-00 11mm eddy current probe preprocessor

BENTLY 330780-91-00 11mm eddy current probe preprocessor

Technical parameter
Input: Receive signals from non-contact 3300 Series 5mm, 3300 8mm or 3300 XL 8mm eddy current probes and extension cables.
Power supply: no safety grid requirements -17.5Vdc to -26Vdc, the maximum current is 12mA; When there is a safety grid, it requires -23Vdc to -26Vdc. When operating at voltages higher than -23.5 Vdc, the linear range will decrease.
Supply voltage sensitivity: When the input supply voltage changes by 1 volt, the output voltage changes by less than 2mV.
Output impedance: 50Ω.
Linear range: 4mm (0.16 in), linearity is ±10%.
Repeatability: ±0.5mm (0.020 in).
Operating temperature: -35 °C to + 85°C (-31 °F to + 185°F).
Storage temperature: -51 °C to + 100°C (-60 °F to + 212°F).

Application field
The preprocessor is widely used in power plants, chemical plants, oil refineries, steel plants and other enterprises, and is used in conjunction with Bentley’s 3500/42M module, 3500/50 module, 3500/45 module and other vibration monitoring modules for monitoring the vibration, displacement and other parameters of rotating machinery. Such as steam turbine, compressor, fan, pump and other large rotating machine shaft vibration, differential expansion and other key parameters, in order to timely discover the hidden trouble of equipment, to ensure the safe and stable operation of equipment.
