GFW wind sensor, GFW wind speed sensor Supply

GFW wind sensor, GFW wind sensor supply, GFW wind speed sensor manufacturers zmjt02 GFW GFW wind sensor Products wind speed sensor for coal mine detecting various wind speed wind tunnel and the main 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, output and wind speed frequency signal corresponding to the waveform shaping circuit after treatment GFW15 Mine ultrasonic wind sensor is demodulated wind speed modulation, and then sent to the microcontroller circuit arithmetic processing, and outputs a corresponding frequency signal , and wind speed values ??of local display. GFW15 Mine wind speed sensor microcontroller program memory, data memory, microprocessor and input and output interfaces integration, good performance, high reliability. This product is explosion-proof type of mining intrinsically safe, explosion-proof mark "ExibⅠ". GFW wind speed sensors condition sensor should be able to work properly in the following environmental conditions: a) ambient temperature: 0 ℃ ~ 40 ℃; b) Relative humidity: ≤98% (25 ℃); c) Atmospheric pressure: 80kPa ~ 110kPa. d) Storage temperature: -40 ℃ ~ + 60 ℃. Model significance GFW wind sensor models: GFW15 wind sensor G-- W-- ultrasonic sensor F-- Winds swirl 15-- measuring range, m / s GFW wind speed sensor Features 1, microcomputer processing chip: single-chip computer and high integrated digital circuit, the circuit structure is simple, reliable performance, easy maintenance, debugging. 2, high sensitivity: high performance coupled with the sensor element inside the instrument software automatically makes non-linear compensation for wind detection instrument with high sensitivity. 3, high reliability: This instrument has POST, auto-zero, precision correction function, and infrared remote control adjustment, the machine without any adjustment hole, adjust the instrument zero, precision, and set the alarm value set the output signal by an infrared remote control. Debugging to avoid opening the lid, reduce mechanical damage, improve sealing machine, extending the life of the instrument. 4, good stability: The instrument Karman vortex theory based on the measurement of wind speed is stable and reliable. 5, compatibility: This instrument can set a variety of infrared remote control and flexible output signal system can be connected to almost all types of domestic sub-station. 6, the appearance of compact, simple structure: The instrument board uses SMD soldering, light and beautiful appearance, reasonable structure refinement, excellent sealing, easy to install. GFW wind sensor parameters Measuring range: 0.4-15 m / s, the measurement error: less than ± 0.2 m / s, response time: less than 10s, the amount of display resolution: 0.1m / s transmission distance: more than 2Km output signal: 200-1000Hz or 4-20mA, Power supply: The safe DC9V-24V / 95Ma, Alarm: Intermittent audible alarm display: four LED display, current: ≤70Ma Dimensions: 200 * 125 * 55 Weight: 0.8Kg This products have been exported to many countries, the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran and other customers receive the praise due to production batch, the specific model is different from the above picture for reference only, contact us The sales staff will be specifically verified.
