These Carbon Dioxide sensors contain all the necessary optics, electronics and firmware to provide a linearized, temperature compensated output. The sensors provide equipment designers with a fast track route to introduce the latest infrared technology for detection of Carbon Dioxide gas without the requirement for any specialist knowledge.

They are contained in an Ex d stainless steel housing and are hazardous area certified to IECEx, ATEX and UL standards. The IECEx and ATEX certification also includes Group I (mining) certification. Further information.

The sensors can be used to measure Carbon Dioxide gas within a wide range of commercial and industrial applications. The standard measurement ranges that are available are:-

If you have a requirement for a particular non-standard range then please contact us and we will be please to assist you with your application.

A separately available Configuration Unit enables users to customise certain parameters within the Premier sensor in order to suit their particular requirements - see below.

Sensor Order Codes

The sensor order codes commence with the code MSH-P/CO2 followed by a number of other options such as the number of pins, bridge or voltage output, positive or negative supply etc.

Due to the wide number of variations available, we have published a data sheet that provides detailed instruction of the various options that make-up the ordering code information. To download a copy, click on the following link >> Ordering Details
