Abstract
PURPOSE:To prevent control electronic equipment from malfunctioning and breaking owing to dew condensation by calculating time variation in the environmental temperature of a body to be monitored, and comparing it with a set value and warning dew condensation occurrence. CONSTITUTION:The temperature of the body 1 to be measured is read in form a temperature detector 2 and stored in a storage part 3 at each sampling time. Then it is compared with upper and lower limit temperature values Qmax and Qmin and then a comparative arithmetic part 4 calculates the difference Qe between current detected temperature Qn and last detected temperature Qm, finds temperature variation E by dividing the absolute value ¦Qe¦ of the temperature difference by the sampling time (t), and compares it with a comparison set value Emax. Then when the time variation E in temperature is larger than the set value Emax, it is judged that there is the possibility of dew condensation on the housing of the body 1 to be measured, and a warning device 8 and a warning display device 9 are driven.
