Product Overview

The SGX series of PS1 and PS4 Sulfur Dioxide (SO2) gas sensors utilize a revolutionary Solid Polymer Electrolyte (SPE) technology based on catalytic reaction. These sensors generate a small current proportional to the target gas concentration, offering a stable, high-quality, and cost-effective manufacturing process. They are characterized by their very small size, high sensitivity, low power consumption, and minimal cross-sensitivity to other gases. Ideal for TLV monitoring, the steel industry, emission monitoring, and the oil & petrochemical industry, these sensors provide reliable performance in demanding environments.

Handling Precautions

• Do not solder the sensor directly onto a PCB or to wires; excessive heat could cause damage.
• Use PCB sockets and firmly push-fit the sensor into the application to achieve a correct electrical connection.
• Avoid exposure to high concentrations of solvent vapours during storage, fitting, and operation.
• When using sensors on printed circuit boards (PCBs), use degreasing agents prior to fitting the sensor.
• For life safety performance requirements, check sensors and instruments for response to gas before use.
