Sulfur Dioxide Gas Sensor Tranmsitter
The ATS-109TD Sensor/Transmitter with without Display operates on 24 VDC power and 4-20 mA output and optional alarm relay board. This sensor/transmitter can be connected to various applied controllers or computer-based instrumentation, such as PLC or similar instrumentation.

The ATS-109TD Sulfur dioxide (SO2 Sensor/Transmitters utilize electrochemical type cells to detect the target gas. These cells consist of electrodes, electrolyte and an air/liquid separation barrier. Gas molecules enter the cell and, as a result of an oxidation/reduction reaction, generate an electrical current proportional to the gas concentration
