Patent ID: 7782221

Claim:
An emergency shutdown detection device for a gas turbine, comprising: an elongated, mechanically severable sensor element, which includes at least one electrical line, the at least one electrical line including at least one electrically connected resistor such that upon severance of the sensor element, the electrically connected resistor is electrically disconnected from the electrical line to alter a resistance value for the electrical line; at least one electric supply line and one electric discharge line which are electrically connected to each other in an area of a free end of the sensor element; wherein the supply line includes a resistor R 3 arranged in series and subsequently two resistors R 2 and R 1 arranged in parallel with the discharge line, with the supply line and the discharge line being electrically connected only by these two resistors R 2 and R 1 wherein the gas turbine is shutdown in response to the altered of said resistance value.
