Noncontacting current sensors

We have developed and produce a wide range of noncontact current sensors used for measuring direct, alternative or pulse current values, oscillographic testing of current signals, and galvanic isolation of electrical power circuits from metering circuits. The operation principle is based on measuring the value and direction of magnetic field created by controlled current in the gap of magnetic circuit with the help of Hall converter.

There are three designs available depending on the value of magnetic field to be tested.
