The HZD-B-X vibration transmitter is equipped with an ST vibration velocity sensor, which is used to measure the vibration of rotating mechanical bearings and output analog current signals. It can be connected to computers, DCS, PLC systems, paperless recorders and other equipment.
Fault monitoring: Monitor the vibration of rotating machinery, such as casing vibration, bearing vibration, frame vibration, etc; Monitor the increase in vibration caused by rotor imbalance, misalignment, loose components, damaged rolling bearings, gear damage, etc.
Measurement parameters: displacement, velocity.
Unit type: Monitoring of vibration in small and medium-sized units, such as steam turbines, fans, compressors, motors, pumps, gearboxes, etc; Especially suitable for the renovation of old units.
Installation requirements: Only one screw hole needs to be drilled on the casing to fix the sensor on the double headed screw, without any operation inside the machine.
