WMKY-2000 chlorine detection startup emergency annunciator is an explosion-proof safety equipment that can continuously detect the concentration of toxic gas. DC 24V Power Supply Power supply to realize uninterrupted detection of chlorine concentration in the environment all day long. It can display and start emergency signal on site. The start emergency signal signal can also be transmitted to the centralized control center (duty room). Connect the computer to store and print data. Start the emergency signal signal to start Solenoid valve Connect the fan. When the chlorine concentration reaches the preset start emergency signal value of the toxic gas detector, it is transmitted to the gas detection start emergency signal controller through the cable, and the start emergency signal controller sends the start emergency signal signal to prompt the on-site staff to take necessary protective measures and drive the exhaust, cut-off and spray systems, It can effectively prevent poisoning accidents caused by toxic gases.
WMKY-2000T chlorine detector is composed of imported high-performance sensor and high speed signal processing module. The weak signal output by the sensor is converted into a signal output proportional to the measured concentration through the signal processing module, which can be easily introduced into DCS, PLC system or other Control system to realize startup emergency signal and control. Use the startup emergency signal controller provided by our company to form a set of gas detection startup emergency signal system.
