VQ6MB

The SGX VQ6 Thermal Conductivity series device consist of two matched elements which are used for the detection of gases in 0 – 100% by volume concentration. 

 

The elements operate on the thermal conductivity principle. The sensing element is open to the atmosphere under test and the reference element is supplied sealed in reference air. The response of the devices is dependent upon the difference between the thermal conductivity of the atmosphere under test and the reference air. When the atmosphere under test has a thermal conductivity higher than the reference air, the sensing element loses more heat to the surroundings than the reference element. This increased heat loss causes a cooling of the sensing element and a subsequent reduction in the resistance of the sensing element compared to the reference element.

 

 

The VQ6MB has the following unique characteristics:

Standard Pellistor Pair

Bridge power consumption is 0.75 watts
