Patent ID: 7095235

Claim:
Monitoring device for temperature monrtoring with an accumulator-driven hand-held machining tool, with at least one switch element ( 12 ) for separating an electrical consumer ( 14 ) from a current supply device ( 10 ), wherein for determining a first temperature (T MOTOR ) of the consumer ( 14 ), a first sensor ( 16 ) is connected to the consumer ( 14 ), whereby the first sensor ( 16 ) is connected with a control input of the switch element ( 12 ) and/or with an optical and/or acoustical display unit ( 26 ) for controlling a switching process as a function of the first temperature (T MOTOR ), and wherein a second sensor ( 20 ) is provided in addition to the first sensor ( 16 ), wherein the second sensor determines a second temperature (T ACCU ), whereby both sensors ( 16 , 20 ) are connected with a control input of the switch element ( 12 ), in order to control the switching process as a function of the first temperature (T MOTOR ) and the second temperature (T ACCU ).
