Coal Mine Use Tension  Sensor

1. The tension sensor is simple in structure, easy to install, use and carry;
2. It has better sealing and moisture-proof performance;
3. It has high stability against vibration and shock;
4. The structural design ensures that the transmission error is small and the measurement is reliable, and has good static and dynamic characteristics;
5. Can be used for long-distance static and dynamic measurement.


Technical parameters
1. Normal working conditions
2. The ambient temperature is -5ºC~+40ºC;
3. The altitude does not exceed 2000m (86kPa~110kPa);
4. The relative humidity of the surrounding air is not more than 98% (25ºC);
5. In mines containing explosive mixtures of methane;
6. Places without significant shaking and shock vibration;
7. The place where dripping water can be prevented in the environment of non-damaging gas or steam.
8. Intrinsic safety parameters: Ui: DC12.5V, Ii: 10mA, Li: 0.1mH, Ci: 0.1μF;
9. Input signal: 4~20mVDC, output signal: 2~5VDC, error: ±8%.


Technical requirements
1. All signs of the product should be clear and upright and installed firmly.
2. Measuring range and protection characteristics
A tension of 0-100KN is applied to the mine-used intrinsically safe tension sensor. The output end of the mine-used intrinsically safe tension sensor should output a DC signal of 2-5V, and the error should be ≤±10%.
