Current Sensors

Current sensors with high accuracy are made for a variety of uses, including some that involve considerable direct current or very high primary current. For instance, closed loop current sensors are designed for the utmost precision. They use feedback mechanisms to balance the magnetic field created by the current being measured. That sort of design really cuts down on thermal drift and gives you something closer to an ideal temperature compensation. It's quite effective in a wide range of sensor applications, even under varied operational conditions. However, there are also open loop sensors that use the Hall Effect. They provide a simpler solution with less power loss and, as a result, are something that you could also call "heat-free" in most applications.

Current sensors have signal-conditioning electronics built into them to greatly enhance their usability. When a current sensor measures the current flowing in a conductor, it then processes that measurement into a usable signal. That signal can then be interfaced with a variety of control systems and serve many different functions. For example, it can be used to help regulate a power supply. Or it might be used to help monitor some operational parameter in an industrial setting. The Hall Effect is extremely good at detecting small changes in magnetic fields and is therefore very good for making current sensors. They are also reliable, and that is another plus when making sensors for industrial settings.
