The Bentley 330980-51-00 is a vibration and displacement sensor in the Bentley 3300 XL NSv series.Product details are as follows:
Function:This sensor is compatible with the Bentley 3300 XL NSv eddy-current proximity probe.It receives signals from the 3300 XL NSv eddy-current probe and extension cable.The system outputs a voltage signal proportional to the distance between the probe tip and the surface of the conductor being measured.It can measure both static displacement and dynamic vibration,primarily in oil-film bearing machinery,as well as vibration and displacement measurements,and key phase and speed measurements.
Technical Parameters:
Input:Receives signals from non-contact 3300 Series 5mm,3300 8mm,or 3300 XL 8mm eddy-current probes and extension cables.
Power Supply:Without a safety barrier,the system requires-17.5Vdc to-26Vdc,current 12mA;with a safety barrier,the system requires-23Vdc to-26Vdc.Supply voltage sensitivity is less than 2mV of output voltage change for every 1V change in input supply voltage.
Extension Cable Capacitance:Typical 69.9pF/m(21.3pF/ft).
Operating Temperature:-35°C to+85°C(-31°F to+185°F).
Storage Temperature:-51°C to+100°C(-60°F to+212°F).
Features:The 3300 XL 8mm Eddy Current Sensor System’s probes,extension cables,and proximitor amplifiers are fully interchangeable,requiring no separate matching components or bench calibration.The system also offers strong immunity to radio interference,reducing installation complexity.Application areas:Widely used in steel,electric power,metallurgy,chemical,petrochemical and other industries,and can be used for vibration monitoring of large and medium-sized rotating machinery such as turbines,compressors,fans,water pumps,coal mills,gear boxes,motors,etc.
