Alarm benzene, benzene gas alarm, gas alarm concentrations of benzene, benzene gas leak detection ..

Industrial fixed benzene gas alarm gas alarm control panel from benzene and benzene gas detectors, gas alarm control panel can be placed in the duty room, main control for each monitoring point, benzene benzene gas detector is mounted on the most vulnerable leak place, the core component is a built-in benzene gas sensor, the sensor detects the concentration of benzene gas. Detector converts the gas concentration detected by the sensor into an electrical signal, transmitted by cable to the control panel, the higher the concentration of benzene gas, the electrical signal is stronger, when benzene gas concentration reaches or exceeds the alarm set point alarm controller, gas alarm control panel alarm signal, and start the solenoid valve, exhaust fan endures associated equipment, automatically excluded risks. Fixed benzene gas alarm imported catalytic combustion sensor, catalytic combustion principle is to use a refractory metal platinum wire heating to measure the change in resistance of benzene gas concentrations. When the benzene gas entering the detector, the surface of the platinum wire caused by oxidation (flameless combustion), heat generated increases the temperature of a platinum wire, and a platinum wire resistivity will change. Catalytic combustion sensor for a wide variety of combustible gases have a keen response. This technique has general applicability for combustible gas. Sensors specially designed anti-poisoning function reliably in most industrial environments work five to ten years.
