Introduction
A gas detector is a flameproof safety device that can quickly, reliably, and stably continuously detect gas concentration 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 equipment to remind on-site staff to take necessary protective measures, preventing gas-induced combustion accidents.
Working principle of gas detector: The detector installed on-site operates with power supply. When a gas leak occurs, the sensor converts the detected leakage 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 equipment.
A gas detector is a fixed instrument that can continuously detect oxygen concentration or the concentration of toxic, harmful, flammable and explosive gases in the working environment.
The gas detector adopts a diffusion method to real-time convert the gas concentration signal at the monitoring point into an electrical signal. After this signal is amplified, it is processed by the CPU through AD sampling, temperature compensation, and intelligent calculation. If the measured value exceeds the set alarm concentration value, an alarm signal will be sent out.
The gas detector features a dual-chamber design, special imported sensors, and the sensors adopt a modular design, making calibration and adjustment more convenient. It has superior performance, high stability, can output multiple sets of signals, and is easy to install and maintain, meeting the high reliability requirements of industrial on-site equipment.
