Канальные Гора Угарный газ передатчик

ApplicationsBuilding standard request good ventilation in parking garages, engine repair shops and tunnels. So we should keep enough fresh air supply in the ventilation system. When the concentration of carbon monoxide is less than 25ppm or 50ppm, we can decrease the ventilation or even stop it. Based on this principle, we can use carbon monoxide transmitter to monitor the ventilation. It could ensure the indoor air quality and save the energy cost for unnecessary ventilation at the same time. CMD and CMW transmitters are designed for this application. The CO sensor uses electrochemical technology, has 5 years guaranty. Features Electrochemical technology sensor with high accuracy and long term reliability Digital technology Multiple output and range selectable five years sensing life Easy to change the sensor, save cost at most State of art housing design, easy to install and mainta Specifications Sensing principal:Electrochemical Sensor life:5 years Work temperature:0-50°C,0-90%RH(Non-condensing) Storage temperature:-40 -70°C Sensing range:0-100/200/400ppm Repeatability:Sensing value+/-5% Linear accuracy:Sensing value+/-5% Suggested recalibrate interval:1 year Response time:T90=< 60s Warm up time:<2min Power supply:18-30VDC Power consumption:20mA Output:4-20mA/0-10V/RS485 Protection:IP30(CMW), IP65(CMD) Optional LCD display: LCD display panel could be ordered and installed on field separately (CMW).
