Principle
The sulfur dioxide detector adopts diffusion, flow or pump-suction Sampling method to detect sulfur dioxide gas concentration in the environment through Sensor. The instrument converts the detected gas concentration signal into an electrical signal, which is processed by a 32-bit microprocessor and a 24-bit ADC data collection chip. After processing, it is transmitted to the receiving device through various signal output methods such as 4-20mA, RS485 or relay, so as to realize real-time monitoring and alarm function of gas concentration.
Applications
Petroleum, chemical industry, metallurgy, refining, gas transmission and distribution, biochemical
