GSC200 intelligent speed sensor, speed protection, belt slip sensor, rpm monitor 
 Mainly used for monitoring coal mine belt conveyor belt slip due to the pile of coal on the belt conveyor driven wheel speed, respectively, divided into 1, 2, 3, r / s third gear, for the scene setting with normal speed sensor output "speed" high output, when the driven wheel speed is lower than the setting value of 25% after 10 to 15 seconds delay, GSC200 type speed sensor output speed and output low, the host automatically cut the belt machine power, low-speed protection. GSC200 type speed-based security-type fully enclosed structure, there are three terminals for mating with the host. 
 Operation performance and parameters 
 a proof mark: Ex [ib] i; 
 b, the atmospheric pressure :80-106kPa; 
 c, the ambient temperature is not higher than +40 ° C, not less than? ° C; 
 d, the ambient air relative humidity not more than 95% (20 ± 5 ° C); 
 e, in the absence of a significant shake and shock vibration; 
 f, in the environment without enough to corrode metal or destroy insulation gases and vapors; 
 g, the dripping and liquid immersion; 
 h, the grid voltage to allow the fluctuation range: -25% to +10%; 
 i, Operating voltage: DC +12 V, current ≤ 80mA; 
 adjustment range: Any set. 
 k between the sensor and the host to connect a maximum cable length does not exceed 500m. 
 l, with high and low output, 200-1000Hz frequency and relay contact output function. 
 Magnet across the detection surface to a certain speed, pressing the calibration button calibration at this time for the normal speed (considered as 100%), when the speed from 50% to 70% times the speed of the speed sensor in the 10s about the action, when the speed of small equal to 50% or greater than equal to 110% of the speed, the speed sensor output control signal should immediately start action. 
 Magnet fixed to the driven wheel end, the speed sensor to the rack, sensor side close to the magnet. The normal operation of the belt conveyor, press the calibration button.
