Inductive sensors for stroke current and field measurements

Abstract: The article presents the parameters and measurement capabilities of three induction sensors. Two sensors are inductive coils differing in winding configurations and dimensions. The third sensor is Rogowski coil. The results are verified against reference Montena B-dot SGM2G sensor and Pearson current monitor. The results of 8/20us and 4/16us standard shock impulse measurements of up to 10 kA will be presented and discussed.

Inductive angular position sensor

Abstract: Inductive sensor for the angular position of a shaft 1 integral with a cylindrical rotor 2 revolving in a stator with wound magnetic circuits 3-4, characterised in that the rotor 2, made in a manner which is known per se of a ferromagnetic material, is associated with means for varying the air gap "e" formed between the rotor 2 and the wound magnetic circuits during rotation of the rotor

Planar Body-Mounted Sensors for Electromagnetic Tracking.

Abstract: Electromagnetic tracking is a safe, reliable, and cost-effective method to track medical instruments in image-guided surgical navigation. However, patient motion and magnetic field distortions heavily impact the accuracy of tracked position and orientation. The use of redundant magnetic sensors can help to map and mitigate for patient movements and magnetic field distortions within the tracking region. We propose a planar inductive sensor design, printed on PCB and embedded into medical patches. The main advantage is the high repeatability and the cost benefit of using mass PCB manufacturing processes. The article presents new operative formulas for electromagnetic tracking of planar coils on the centimetre scale. The full magnetic analytical model is based on the mutual inductance between coils which can be approximated as being composed by straight conductive filaments. The full model is used to perform accurate system simulations and to assess the accuracy of faster simplified magnetic models, which are necessary to achieve real-time tracking in medical applications.

Circuit arrangement for controlling a sensor

Abstract: To provide a circuit arrangement for controlling a sensor by means of a power supply source which is connected to input terminals of the sensor, and an evaluation circuit which is connected to output terminals of the sensor, by means of which the current consumption of a sensor in the standby state can be reduced in a simple manner, the power supply source ( 14 ) is switchable between at least two current levels in dependence upon an output signal level (S) of the sensor ( 12 ).

Sensor and method for measuring electrical conductivity of a liquid

Abstract: of EP0999441The sensor (1) has device (5) for measuring changing signal at the entrance of an excitation coil (3). Inductive sensor (1) to measure the electrical conductivity of liquid medium (2) has an excitation coil (3) which is driven by an entrance signal and a receiving coil (4) coupled to the excitation signal (3) via the liquid medium. The receiving coil (4) delivers an output signal (Iind) which is a measure of the conductivity of the liquid medium (2).
