A292 Micro differential pressure transmitter – Gas series products

The A292 Micro Differential Pressure Transmitter combines the versatility of multi-range sensors with the performance of single-range sensors, making it ideal for industrial use. It offers multiple pressure ranges and unit selections, easily adjustable via a built-in dip switch. With an IP65-rated housing and stainless steel conduit connectors, it allows for straightforward wiring.

A261 Carbon monoxide transmitter

The A261 Carbon Monoxide transmitter utilizes electrochemical principles to detect the presence of carbon monoxide in the air, exhibiting good selectivity and stability. Carbon monoxide and oxygen undergo corresponding oxidation-reduction reactions on the working electrode and counter electrode, releasing charges to form an electric current. The concentration of carbon monoxide can be determined by measuring the magnitude of the current.

A251 Wall-mounted CO2 Transmitter

The A251 Wall mounted CO2 transmitter is based on the fact that different gases have different absorption abilities for specific bands of infrared light. By measuring the degree of absorption of infrared light, the concentration of the measured gas can be measured. Compared with electrochemical sensors, it has the characteristics of long lifespan, good stability, wide power supply range, and anti reverse power protection.
