Introduction
Gas detectors are flameproof safety devices that can quickly, reliably, and stably continuously detect gas concentrations in industrial production. When the detected gas concentration reaches the preset alarm value of the gas detector, the detector will trigger an alarm and drive external devices to remind on-site staff to take necessary protective measures, preventing gas-induced combustion accidents.
Working principle of gas detectors: The detector installed on-site operates on power supply. When a gas leak occurs, the sensor converts the detected leak amount into a corresponding voltage signal for output. After the voltage signal is processed by the detector, the data is uploaded and displayed on the screen. When the concentration reaches the set action value, the detector triggers an alarm and drives external devices.
A gas detector is a fixed instrument that can continuously detect oxygen concentration or toxic, harmful, flammable, and explosive gas concentrations in the working environment.
Gas detectors adopt a diffusion method, which converts the gas concentration signal at the monitoring point into an electrical signal in real time. After the signal is amplified, it undergoes A/D sampling, temperature compensation, and intelligent calculation by the CPU, then the measurement result is processed. If the measured value exceeds the set alarm concentration value, an alarm signal will be issued.
Gas detectors feature a dual-chamber design, dedicated imported sensors, and the sensors adopt a modular design, making calibration and adjustment more convenient. They have superior performance, high stability, can output multiple sets of signals, and are easy to install and maintain, meeting the high reliability requirements of industrial on-site equipment.
