KQ WALL-MOUNTED GAS DETECTOR/SENSOR
KQ single channel wall-mounted gas detector is can be used continuously in operation environment to detect the concentration of combustion gas, oxygen, and toxic gas.
The detector detects gas concentration in natural diffusion way, and uses imported electrochemical sensor or catalytic combustion sensor which has excellent sensibility and receptivity; big LCD displays the concentration of the leaked gas real time.
If the concentration exceeds the preset alarm level, detector will start the acoustic-optical alarm or exhaust system; international standard signal of 4-20mA can be directly connected into the factory DCS system, RS4845 digital signal is connected with factorys principle computer; the device adopts embedded micro controlling technique. The performance of the whole detector is among the best ones in China.
Main features:
l Adopts advanced embedded micro controller(16 digit ultra-low power consumption )
l 128*64 dot matrix ultra-large liquid-crystal display
l User can set the alarm level by themselves
l Displaying the time of fist alarm
l Real-time clock
l Replaceable modularized sensor
l Automatic calibration function, reduce the measuring error.
l Automatically save alarm data for 1000 records
l standby battery can work more than 100 hours in the condition that do not alarm (optional)
l standard signal(4-20mA) can be directly connected to factory's DCS system (optional)
l RS4845 digital signal is connected to factorys principle computer (optional)
