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. Siemens (unit) - Wikipedia

   en.wikipedia.org/wiki/Siemens_(unit)

   The siemens (symbol: S) is the unit of electric conductance, electric susceptance, and electric admittance in the International System of Units (SI). Conductance, susceptance, and admittance are the reciprocals of resistance, reactance, and impedance respectively; hence one siemens is equal to the reciprocal of one ohm (Ω −1) and is also referred to as the mho.

   An electric current is a flow of charged particles, ... Hall effect current sensor ... This means a conductivity roughly in the range of 10 −2 to 10 4 siemens per ...

6. Conductivity (electrolytic) - Wikipedia

   en.wikipedia.org/wiki/Conductivity_(electrolytic)

   Inductive sensors are suitable for harsh chemical conditions but require larger sample volumes than electrode sensors. [9] Conductivity sensors are typically calibrated with KCl solutions of known conductivity. Electrolytic conductivity is highly temperature dependent but many commercial systems offer automatic temperature correction.

7. AS-Interface - Wikipedia

   en.wikipedia.org/wiki/AS-interface

   Actuator Sensor Interface (AS-Interface or ASi) is an industrial networking solution (Physical Layer, Data access Method and Protocol) used in PLC, DCS and PC-based automation systems. It is designed for connecting simple field I/O devices (e.g. binary ON/OFF devices such as actuators, sensors, rotary encoders, analog inputs and outputs, push ...
