Product Overview

The SGX Solid Polymer Electrolyte Gas Sensors, specifically the PS1 and PS4 series, utilize a revolutionary Solid Polymer Electrolyte technology based on catalytic reaction principles. 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, zero power consumption, and low cross-sensitivity to other gases. Key applications include TLV monitoring, the oil & petrochemical industry, leak detection, the steel industry, and parking garages.

Important Notes

• All performance is based on conditions at 20C, 50% RH and 1 atm, flow rate >150 qcm/min, using SGX recommended circuitry.
• Sensor performance is temperature dependent; please contact SGX for temperature performance other than 20C.
• Do not solder to the connector pins as this may damage the sensor and thereby invalidate the warranty.
• Details on recommended connector pins can be found in the Frequently Asked Questions within the Gas Sensor section of the SGX website.
• Exposure to high concentrations of solvent vapours should be avoided during storage, fitting into instruments, and operation.
• When using sensors on printed circuit boards (PCBs), degreasing agents should be used prior to the sensor being fitted.
• For life safety performance requirements, it is recommended that all sensors and instruments using these sensors are checked for response to gas before use.

Cross Sensitivity

Note: Interference factors may vary due to different sensors and service life. This table is not exhaustive for all cross gases; contact SGX for further information.
