2. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   Fluxgate sensors or Saturable inductor current sensors work on the same measurement principle as Hall-effect-based current sensors: the magnetic field created by the primary current to be measured is detected by a specific sensing element. The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect ...

3. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening. Zero current output voltage is midway between the supply voltages that maintain a 4 to 8-volt differential. The non-zero current response is proportional to the voltage supplied and is linear to 60 amperes for this particular (25 A) device.

4. Personal RF safety monitor - Wikipedia

   en.wikipedia.org/wiki/Personal_RF_safety_monitor

   Electromagnetic field monitors, as used in the cellular phone industry, are referred as "personal RF safety monitors", personal protection monitors (PPM) or RF exposimeters. [1] They form part of the personal protective equipment worn by a person working in areas exposed to radio spectrum radiation. A personal RF safety monitor is typically ...

5. Thermistor - Wikipedia

   en.wikipedia.org/wiki/Thermistor

   NTC thermistors are widely used as inrush-current limiters and temperature sensors, while PTC thermistors are used as self-resetting overcurrent protectors and self-regulating heating elements. An operational temperature range of a thermistor is dependent on the probe type and is typically between −100 and 300 °C (−148 and 572 °F).

6. EMF measurement - Wikipedia

   en.wikipedia.org/wiki/EMF_measurement

   EMF measurement. Electric field probe FP2000 (range 100 kHz – 2137 MHz) EMF measurements are measurements of ambient (surrounding) electromagnetic fields that are performed using particular sensors or probes, such as EMF meters. These probes can be generally considered as antennas although with different characteristics.

7. Magnetotellurics - Wikipedia

   en.wikipedia.org/wiki/Magnetotellurics

   For exclusively long-period MT (frequencies below approximately 0.1 Hz), the three discrete broadband magnetic field sensors may be substituted by a single compact triaxial fluxgate magnetometer. In many situations, only the telluric sensors will be used, and magnetic data borrowed from other nearby soundings to reduce acquisition costs.

9. Sensitivity (electronics) - Wikipedia

   en.wikipedia.org/wiki/Sensitivity_(electronics)

   Sensitivity first definition: the ratio between output and input signal, or the slope of the output versus input response curve of a transducer, microphone or sensor. An example is given in the section below on electroacoustics. Sensitivity second definition: the minimum magnitude of input signal required to produce an output signal with a ...
