Definitions
- a basic idea of the invention is to integrate a circuit arrangement for controlling the scavenging process directly into the signal circuit of the thermal power monitor.
- a cyclic cleaning of the contacts is provided, which is carried out simultaneously with the signal query, so that it can take place continuously.
- FIG. 1 shows an exemplary embodiment of a circuit arrangement 1 according to the invention.
- the circuit arrangement 1 is designed to generate cyclically successive current pulses 11,... In, as shown by way of example for two different ambient temperatures in FIGS. 2 and 3.
- the number of current pulses generated by the circuit 1 per time interval is less than in the case of the ambient temperature of 100 ° C.
- TW is the Temperature monitor monitoring signal shown, which can be detected simultaneously with the generation of the current pulses, uninfluenced at the same time.
