Contact: Victor 15,563,491,958 phone is turned on, please wait. . . First, the product name: GFK40T type throttle opening and closing state sensor Description: GFK40T type throttle opening and closing state sensor can be equipped with a variety of coal mine monitoring system, throttle-line detection of coal mine ventilation roadway set "on" and "off" state. GFK40T type throttle opening and closing state sensor (hereinafter referred to as equipment), and various types of coal mine safety monitoring system supporting the use of continuous monitoring of coal mine ventilation roadway set throttle "on" and "off" state, with the sensor sensitivity , easy installation, maintenance and simple. Use of reed contacts, reliable operation up to 108 times. Product Principle: reed in a magnetic field, when the magnetic field reaches a certain intensity, which normally closed contact and the original contact sheet pull the disengagement, the normally open contacts with another pull, when the reed switch from magnetic field, and restore the original state. Using this principle, the group with the reed sensor and generating a magnetic field of the magnet group were installed on the edge of the door frame and the door damper (both relative), use change throttle position switching signal is generated and sent to the monitoring system . Second, the product parameters: 1. Measurement range (0 ~ 30) mm reed relay 3. 2. The output signal switch contact capacity DC36V / 100mA 4. Transmission distance ≥2km 5. proof type Exib I 6.
