Dual-Gas Methane/Carbon Dioxide Infrared sensors

Dual-Gas Methane/Carbon Dioxide Infrared sensors CH4/CO2 Overview：

Dual-Gas Methane (CH4) / Carbon Dioxide (CO2) sensors are revolutionary devices for the simultaneous measurement of Methane and Carbon Dioxide in a single sensor package. They acheive this whilst only consuming the power of a single infrared sensor. The sensors also have the additional benefit of a pre-characterised 0-2% Propane measurement range included as standard.

The sensors provide accurate measurement of gas levels using infrared gas sensing techniques. Various versions are available with combinations of ranges up to 100% volume Methane and 5% volume Carbon Dioxide. They consume the power of a single infrared sensor and therefore provide prolonged battery life when used within portable gas detectors.

The Hydrocarbon channel provides simultaneous readings for both High Resolution Methane and Propane.

·  Hydrocarbon Channel Resolution - 0.01% for range 0 to 10% Vol. and 0.1% for range 10% to 100% Vol. (CH4)

·  Carbon Dioxide Channel Resolution - 0.01% Vol. (CO2)

The sensors are part of the 'Platinum' Series and are available in Industrial Ex d IIC Certified, Mining M1 Certified and Non-Certified versions. They are also UL approved.

Low power and EN50271 / SIL1 certified software versions are also available in all combinations.

Ordering Details 

In order to completely specify the type of sensor that is required, the customer needs to provide the

following information (more information available on TDS0052 Platinum Sensor Ordering Codes):

• An Order Code (see below) that specifies the sensors’ basic physical and electrical

characteristics.

• The sensor configuration requirements, including the required gas measurement ranges.
