Mine GFW15 wind sensor parameters and rates of all economic 宁恒旺 taste - to really sincere, service eternal, Wang Heng electrical equipment company holds quality first, the principle of the interests of the second door to greet customers and friends from around the world, and sincerely welcome you calls! Contact: Victor 15,563,491,958 phone is turned on, please wait. . . First, the product name: GFW15 Mine wind speed sensor II Introduction: GFW15 Mine wind speed sensor is used to detect wind speed coal mine all major wind tunnel and outlet, the main fan wellhead, etc., in order to ensure that coal mines safety in production; GFW15 mining wind speed sensor is intrinsically safe, it is an intelligent instrumentation, easy to use with a variety of supporting the use of coal mine safety monitoring system. GFW15 Mine wind speed sensor to achieve a fully digital design. Winds from the probe selection good stability ultrasonic element, GFW15 ultrasonic wind sensor outputs the demodulated Winds modulated waveform shaping circuit after dealing with wind speed corresponding to a frequency signal, and then sent to the microcontroller circuit arithmetic processing, and outputs a corresponding frequency signal, and wind speed values ??were local display. GFW15 wind sensor microcontroller program memory, data memory, microprocessor and input and output interfaces integration, good performance, high reliability. Third, the product parameters: 1. Explosion-proof form of mining intrinsically safe "ExibI" 2. Measuring range wind speed 0.3m / s ~ 15m / s 3. Hang sectional area of ??less than 30m / s (can be set) 4. Allow the error is less than ± 0.3m / s 5. repeatability error reading value + 1% 6. Output signal 200Hz ~ 1000Hz / 5Hz ~ 15Hz 4 ~ 20mA / 1 ~ 5mA / RS485 bus 7. The safe working voltage DC12V ~ 18V 8. Working current is less than 100mA 9. transducer operating frequency 140 ~ 150kHz 10.
