YZHB intrinsic safety vibration transducer integrates magnetoelectric velocity transducer and precision
measurement circuit to realize the functions of traditional vibration measurement system defined by the model
“sensor+ transducer”. It is suitable to construct an economical high-precision vibration measurement system. The
transducer can be directly connected with DCS, PLC or other systems. It functions as an ideal equipment for
measuring the vibration of fan and pump.
The reliable intrinsic safety design enables YZHB intrinsic safety vibration transducer to operate in the flammable
and explosive environments. The intrinsic safety is rated as Exia II CT6. To meet the needs of measurement, we
provide three-wire system, two-wire system, vibration speed, vibration displacement and the transducer with
multiple measuring ranges. According to the requirements on operating environment and installation, we supply
three kinds of basic models and mounting threads of various specifications.
