Abstract
A temperature supervising system comprising a temperature sensor which is designed to sense the temperature of the supervised component and to supply a signal representing the temperature, which signal is compared with a reference signal to produce an alarm or to interrupt the connection of the component to a supply source when the difference between the signal indicating the temperature and the reference signal exceeds a given value, for example zero. The reference signal is generated by a function generator which supplies a signal varying with time, which signal, in a period immediately after the instant the component is connected to its current source, increases according to any desired function, for example stepwise or linearly, from a low initial value to a higher output value.
