ABSTRACT:
A rod sensor (1) has in the vicinity of a sliding guide (17) of an outer tube (2) a bolt-like, smooth abutment (4) for an inner rod (3), which prior to the insertion of the inner rod (3) and prior to the constructional joining of the temperature sensor (1) to a switch base (10) is adjusted with a measuring screw (36) against the tension of a spring (39) to a predetermined adjusting amount (30) and is firmly connected to the outer tube (2) by a welding mechanism (40) or the like. Thus, a very accurate adjustment is obtained in the case of a simple construction.
