GS-AQ-x-UN Air Quality Transmitter

GS-AQ-x-UN Air Quality Transmitter

This single analogue universal sensor has a valuable feature - its ability to automatically detect what the controller input is set to, 4-20mA or 0-10Vdc. This removes the requirement for output jumpers that can be inadvertently set incorrectly. On board LED indication of which output type is in operation is provided. Also available with a passive resistive output for temperature, along with other passive outputs.

GS-CO Carbon Monoxide Sensors

GS-CO Carbon Monoxide Sensors

Sontay’s range of CO sensors offer real time detection for Carbon Monoxide measurement. A valuable feature of this sensor is when in 3-wire mode it automatically detects what the controller input is set to, 4-20mA or 0-10Vdc. 2-wire loop powering selectable via DIP switch. The long life electrochemical Carbon Monoxide sensor makes it ideal for many applications including underground parking, loading bays and warehouses.
