ZHJ-402 integrated vibration temperature transmitterZHJ-402 integrated vibration temperature transmitter

It mainly consists of three parts: X horizontal vibration measurement, Z vertical vibration measurement, and bearing temperature measurement. Two vibration velocity sensors are internally packaged, with a low-frequency response of up to 5Hz and stable and reliable performance. Temperature measurement uses Pt100 platinum resistors as sensing elements, which are packaged in probes with compression springs to ensure temperature transfer between Pt100 platinum resistors and bearings. twelve

A vibration velocity sensor utilizes the principle of magneto electric induction to convert vibration signals into electrical signals. It mainly consists of a magnetic circuit system, coil components, spring damping, and other parts. Two coil components are rigidly fixed in the sensor housing, and magnetic steel is suspended from the housing by springs. When the sensor operates within the working frequency range, the coil and magnetic steel produce relative motion, and the coil cuts the magnetic field lines, generating induced electromotive force (induced voltage), which is proportional to the vibration speed of the casing.
The temperature measurement of a temperature sensor utilizes the linear variation of platinum resistance with temperature to measure temperature.
