Abstract: Fiber optic sensors are described for detecting the operational position of a downhole moveable device. In one example, an electric or magnetic field is emitted into the wellbore and interacts with the moveable assembly, thereby producing a secondary electric or magnetic field. The secondary field is detected by a fiber optic sensor which produces a corresponding response signal. The response signal is then processed in a variety of ways to determine the operational position of the moveable device. In another example, the operational position is determined using fiber optic temperature or acoustic sensors. A temperature or acoustic vibration reading is acquired before and after actuation of the moveable device. The two readings are then compared to determine the operation position of the moveable device.

Abstract: A cable condition monitoring sensor device includes a TMR magnetic field sensor module, a high-pass filtering module, and a signal-amplifying module which are sequentially connected. The TMR magnetic field sensor module measures a magnetic field change signal of a cable, converts the same into a voltage signal, and outputs the voltage signal to the high-pass filtering module. The high-pass filtering module filters out DC bias of the voltage signal, and transmits the filtered voltage signal to the signal-amplifying module. The signal-amplifying module amplifies the filtered voltage signal to obtain an output voltage signal and outputs the output voltage signal. In the present invention, a common mode current to be measured in the cable is extracted by placing the magnetic shielding ring made of ferromagnetic material outside the cable to filter out a differential mode load current in the cable, and the magnitude of the common mode current is determined.
