Abstract:
A compensated gas detector incorporates first and second pellistors combined with first and second resistors and an intervening switch. Control circuits can close the switch for normal gas detection. The switch can be opened to carry out diagnostic measurements. A compensation coefficient can be established in order to compensate outs from the pellistors due to mechanical damage thereto.
