Abstract: In one example, the present disclosure describes a magnetic temperature sensor. For instance, in one example, an apparatus includes a first magnet, a magnetometer housing the first magnet, and a temperature converter coupled to the magnetometer. The first magnet includes a material having a magnetic field whose strength fluctuates in response to changes in temperature. The magnetic field induces an electric current in the magnetometer. The temperature converter then converts a measurement of the electric current to a corresponding measurement of temperature.

Abstract: A method and an apparatus for monitoring a temperature of a coil wire of a solenoid valve are provides. An actuation signal has actuation intervals which follow one another is used in this case, wherein a start pulse, which causes an increase in current in the coil wire of the magnet coil and has a prespecified pulse duration, and a pulse sequence, which follows the start pulse and has a duty cycle, are provided in each actuation interval. The current intensity of the current flowing through the coil wire of the solenoid valve is measured at two different times during the increase in current, and the current gradient is subsequently calculated from the measured current intensities. A prespecified threshold value for the current gradient is then compared with the calculated current gradient.

Abstract: Systems and methods for monitoring temperature distribution in downhole equipment using magnetostrictive probes. In one embodiment, an ESP motor has a stator with a rotor and shaft rotatably positioned within the stator. Magnetostrictive sensors are positioned within the motor. Each magnetostrictive sensor has a transducer, a probe, and electronic circuitry coupled to the transducer. The circuitry generates an initial electrical signal that is conveyed to the transducer. The signal passes through one or more coils in the transducer, generating magnetic fields that induce an acoustic signal in the probe. The acoustic signal propagates through the probe and waves are reflected from reflection points in the probe. The transducer senses the reflected acoustic waves and provides corresponding electrical signals to the circuitry, which determines timing intervals associated with the reflected waves and uses this information to determine temperatures at one or more locations in the probe (hence in the monitored equipment).
