Key Specifications/Special Features:

• MD62 gas sensor consists of an active element and a reference element with the same resistance, both elements are placed in a wheatstone bridge circuit
• The analyzing gas contents changes, the overall thermal coefficient of mixed gases changed correspondingly
• When the active element meet the combustible gas, its resistance become smaller when it meets other gas
• Its resistance become larger (air background), the bridge circuit output the voltage change, this change increase according to gas concentration, the reference element as a benchmark while for temperature compensation
• Features:
  • Wide detecting range: 0 to 100% vol
  • Linear output signal
  • Quick response
  • Good reproducibility and reliable performance
