Why Is A Three Wire System Used On The Sensors? |
|
Answer» The three-wire system is used to COMPENSATE the line resistance. The active and non-active FILAMENT loop form a whetstone bridge in the GAS monitor. The amount of unbalance in the current loop during the OCCURRENCE of combustible gas is detected as the PERCENTAGE of combustible gas. The three-wire system is used to compensate the line resistance.
