Tips: Features of explosion-proof vibration transmitter
In the structural design of the explosion-proof vibration transmitter, it is fully considered that when the explosive mixture invades its interior and explodes for some reason, The explosion-proof vibration transmitter will not cause the explosive material outside the sensor to explode. From the strength of the shell and the gap between the joints of the parts that make up the shell, Length and limit the maximum surface temperature of the shell and other key conditions to ensure explosion-proof performance.
- The external grounding of the explosion-proof vibration sensor is an important measure to ensure its safe operation. The sensor and the object to be measured are firmly connected by stainless steel mounting screws and connected to the ground.
- Resistance to strong electromagnetic field, vibration measurement and shock vibration measurement.
- Because the piezoelectric crystal and the amplifier insulation.
- structure are connected to the ground, the loop current is completely eliminated.
- High sensitivity, high resonance frequency, thermal shock resistance, low level of noise.
- For the rotor supported by rolling, the vibration will be large enough to be transmitted to the bearing seat, and the sensor installed on the seat or very close to the housing will output the voltage by cutting the magnetic lines of force by the internal motion coil, and provide the signal to the detection instrument for correcting Predict and alarm for mechanical failure.
The explosion proof vibration transmitter has a wide velocity range from 10 mm/s to 50 mm/s, 4-20 mA output current. This type of explosion proof vibration sensor is used with a variety of test systems, provides high reliability and measurement accuracy. It is your best choice.
