GRG5H carbon dioxide sensor factory outlets are welcome to visit the factory of economic 宁恒旺 - 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 your calls ! Contact: Victor 15,563,491,958 phone is turned on, please wait. . . First, the product type: GRG5H two carbon dioxide sensor, carbon dioxide sensor Description: The product adopts the international advanced non-dispersive infrared detection technology to overcome the hot catalytic principle sensor calibration cycle is short, easy to poisoning and other defects, and the use of embedded microcontroller technology, built- Accurate temperature compensation circuit so that the detection accuracy will not drift due to temperature changes. The instrument has a measurement accuracy, fast response, long calibration cycle, from other gases influence, wide measuring range, low power consumption, long life, stable performance and high reliability. The instrument can be easily set up to work point by remote control, with the output frequency signal and RS-485 digital signal 200 to 1000 Hz, convenience and various types of supporting the use of coal mine safety monitoring system. Mainly for coal mine mining face, back to the wind tunnel, electrical and mechanical Cave rooms have gas explosion gas environment for continuous measurement of gas concentration. The instrument has measured the instantaneous display of gas concentration, limit alarm and output power control signals, infrared remote control adjustment, digital communications and other functions. Third, the carbon dioxide sensor parameters: Measuring range (0.00 ~ 0.50)% CO2 (0.50 ~ 5.00) (5% 0.05+ true value)% CO2 basic error of ± 0.10% CO2 ±% CO2 resolution of no less than 0.01% CO2 corresponding Time ≤25s Power supply DC 9V ~ 24V / 95mA (intrinsically safe power supply) Alarm intermittent sound and light signals, optical signals in the dark visibility is not less than 20m remote control distance ≤5m transmission distance ≤2km output signal frequency (200 to 1000 ) Hz; output high is greater than 3V (load resistance> 1.5 kΩ) digital signal RS485 1200bps ~ 9600bps optional way mine explosion intrinsically safe, explosion-proof mark ExibI Operating temperature 0 ℃ ~ 40 ℃ Relative humidity ≤98% (+ 25 ℃) Storage temperature -20 ℃ ~ + 50 ℃ Dimensions 260mm × 120mm × 50mm Weight ≤1kg DC (9 ~ 24) V / 250mA (intrinsically safe power supply) output signal (200 ~ 1000) Hz, RS485 (baud rate transfer) type of protection Exib I display 4 LED Dimensions 250 × 220 × 120mm economy Ningheng Wang mining service package for you!
