Abstract

PURPOSE:To ensure the stable working of a sequence controller by fixing a dew condensation detecting element onto a wall surface of a case storing the sequence controller. CONSTITUTION:A dew condensation detecting element 3 is fixed onto a wall surface of a case 2 storing a sequence controller 1 detects the dew condensation as a change of the electrical characteristics like the resistance value, etc. The wall surface temperature of the case 2 is lower than the temperature of the controller 1. When the atmospheric temperature drops in the case 2, the dew is condensed first on the wall surface of the case 2 and the surface of the element 3 where the temperatures are kept at low levels. Therefore the controller 1 can know that its atmosphere is approximate to a dew condensing state after the element 3 detects the dew condensation. Thus it is possible to take a measure to the dew condensation before the controller 1 has a malfunction by occurrence of the dew condensation.
