Temp. measuring monitor for friction clutch

摘要

An enclosed, low-ohmic current circuit is formed from two thermo-elements: one (17) for measuring the high temp. and the other (18) for the lower temp. Part of this circuit is in the form of a circulating coil (13). The current flowing in the latter is contactlessly transferred by magnetic inductance to a fixed receiver (14) as a measure of the temp. difference between the thermo-elements. One (3) of the friction surfaces of a friction clutch is assigned the first thermo-element (17), pref. the driving plate of the clutch. The circulating coil is pref. in the form of a wire loop moving close to the sec. coil (14) installed on a core (19) with a slit, the loop passing through the latter.
