Abstract
An electrosurgical system includes an electrosurgical instrument coupled to an electrosurgical generator. The electrosurgical system may include a first sensor and a second sensor, which are configured to detect redundant tissue properties and output a signal corresponding thereto. The electrosurgical system has a signal processing circuit for receiving and modifying the output signal from the second sensor. The electrosurgical generator may include a controller for receiving an output signal from the first sensor and a processed signal from the signal processing circuit. The controller compares the two signals received and shuts down the system based on the comparison of the first sensor and a processed signal.
