MJ-VR9400 Explosion-proof Vibration Sensor

Explosion-proof 4-20mA vibration velocity sensor can connect to the job site of PLC system.

IEC 60079-10 explosion-proof certification

MJ-VR9400 Integrated Explosion-proof Vibration Transmitter is mainly installed on the bearing cover of various rotating machinery (such as steam turbine, compressor, fan and pump etc.), capable of measuring the vibration velocity or vibration amplitude. The moving coil cuts magnetic lines to generate voltage, and the transmitter convert it to current output. The transmitter has the advantages of small size, water proof, stable performance, easy installation and so on.

● Output current: 4~20mA

● Output impedance: ≤500Ω

● Working voltage: DC24V

● Connecting mode: two wires (DC24V Power and 4 ~ 20mA use 2 wires) or three wires ( ground wire, power wire and output wire )

● Maximum acceleration: 10g

● Measurement direction: horizontal or vertical

● Environmental conditions: temperature is -40℃~85℃, relative humidity ≤90%

● Dimensions: aluminum alloy, 72×132mm

● Weight: about 450g

● Mounting screw: M20 x 1.5 x 20mm ( length)

Mounting position: vertical or horizontal install on the measured vibration point, fix it by M20 x 1.5 x 20 screw on the bottom of the transmitter.

MJ-VR9400-A□

Measuring range: A□

1 0~200um; 2 0~500um; 3 0~1000um ( Vibration amplitude ); 4 0~10.0mm/s;

5 0~20.0mm/s; 6 0~50.0mm/s ( Vibration intensity ).

For example: MJ-VR9400-A1 means the measuring range is 0~200um.
