ZP-12C mine inherently secure touch sensor

Introduction of zP-12C Mine intrinsic safety touch sensor

The touch sensor is a level output touch switch composed of special high-sensitivity vibration element, voltage converter V/V transformation, RC inverse time sampling, Schmidt shaping and memory holding circuit, output interface circuit, etc. The motion of the material is detected by the probe rod of the touch sensor, and the signal is processed. The output level signal reflects the motion state of the material, providing reliable detection signal for comprehensive dust control and material transportation state detection. The work is stable and reliable, without calibration.

Zp-12c mine application range of intrinsically safe touch sensor

The touch sensor is suitable for coal mine underground with gas, coal dust explosive gas place, but its power supply must use the intrinsically safe power supply; It is suitable to be applied to detection of block sports materials such as mine belt conveyer scraper conveyer to provide reliable detection signals for comprehensive dust control and material transportation state detection.

Working principle of ZP-12C mine inherently secure touch sensor

The touch sensor is a highly sensitive vibration element, which is composed of a level output touch switch consisting of a vibration sensor and vibration induced voltage transformed by a voltage converter V/V, RC inverse time sampling, Schmidt shaping and memory holding circuit, and an output interface circuit.
