CFJD5 Mine electronic anemometer characteristics and uses CFJD5 Mine electronic anemometer, microprocessor technology, with direct reading display, data access, the measured value of accurate, easy to use functions and features. For measuring the presence of explosive mixtures of flammable gases in the working environment the average wind speed. CFJD Mine electronic anemometer is a new generation of intelligent digital wind speed detector for detecting the presence of explosive mixtures of flammable gases in the environment mean wind speed. Having a direct reading display, measuring the value of accurate, data access, adjustable, easy to use functions and features. CFJD5 performance standards MT380-1995 Mine electronic anemometer "Mine anemometer", Q / SD 020-2007 "Mine electronic anemometer" Mine electronic anemometer measurement works, since the impeller rotation photoelectric sensor is formed block, every block once to produce a light pulse signal, the pulse signal is transmitted to the microprocessor for computing counter processing, via display or stored in memory to save. CFJD Mine electronic anemometer main technical indicators Project CFJD5 type CFJD25 type measuring range (0.3 ~ 5) m / s (0.5 ~ 25) m / s basic error ≤0.2m / s ≤0.3m / s start wind speed ≤0.2 m / s ≤0.4m / s proof in the form Exib I Mb 3-digital LED display of the battery pack 3 × FSM500mAh continuous working time> 24h Dimensions 50 × 25 × 155mm Weight 0.18kg equipment single charger
