Description
A High Resolution Methane sensor for the measurement of Methane gas over the range from 0 to 100% volume Methane. Its high resolution capability allows it to replace two individual infrared Methane sensors at no extra cost. These sensors consume the power of a single infrared sensor and therefore provide prolonged battery life when used within portable gas detectors.
These Methane 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 Methane gas without the requirement for any specialist knowledge.
The sensors are are intended for use either in non-certified gas detection equipment or in hazardous area certified equipment where the equipment manufacturer provides the necessary protection by means of a separately certified explosion protected housing.
They are contained in a stainless steel housing fitted with a single protective stainless steel mesh. This ensures a minimum response time to gas in applications where the sensor is to be fitted within a separately certified explosion protected housing protected by a sintered flame arrestor such as a sinter.
The construction of the non-certified types provide a small cost saving compared with the certified types.
The sensors can be used to measure Methane gas within a wide range of commercial and industrial applications. The standard measurement range covers 0-100% volume Methane (CH4). 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 sensors are within the High Resolution Premier Series which commence with the code MSH-P/HR/NC followed by a number of other options such as the number of pins, bridge or voltage output, positive or negative supply etc. Refer to end of the Technical Data Sheet for details.
(Note - infrared sensors cannot be used to detect Hydrogen)
Configuration Unit
The Premier Sensor Configuration unit enables users to customise certain parameters within the Premier sensor in order to suit their particular requirements. The unit is supplied complete with a PC software configuration package. Versions of the unit are available for either positive or negative supply sensors. Ordering details are as follows:
Positive version - Type P/CONFIG/POS
Negative version - Type P/CONFIG/NEG
