Detailed Product Description

Fixed Gas Detector Description
TC100N is a fixed gas detector installed in a place where potential gas hazard exists to measure oxygen, toxic gas and combustible gas. With ATEX approval, it is suitable for explosive environment use. it communicates with the control panel through 4-20mA analog output or RS485 digital signal. 

The fixed gas detector is uesd forSteelworks, Petrochemical plants, Shipyards, Water treatment plants, Mines. Power plants, Food industry etc.

Fixed Gas Detector Key Features

  • ATEX approved
  • 4-20mA analog or RS485 digital output
  • 2 relay output for 4-20mA type
  • Sensor module design, easy for replacement

Different sampling methods

Natural diffusion is that the gas in the detected area flows slowly into the instrument for detection with the free flow of air, and needs to be placed on site. This method is affected by the detection environment, such as ambient temperature, wind speed, etc., and is not suitable for gas sources with low pressure. The advantage is low cost.

The pump suction type is that the instrument is equipped with a gas sampling pump. Its working method is that the power supply drives the gas sampling pump to extract and sample the gas in the test area, and then the sample gas is sent to the instrument for detection.The characteristics are fast detection speed, long-distance measurement of dangerous areas, and safety of maintenance personnel. It is suitable for occasions where the gas detector cannot be placed on site and has special requirements for reaction speed, pressure difference, etc.
