Current Transducer-High Accuracy Current Sensor

The high accuracy closed loop current sensor is a newly developed current transducer based on the principle of hall effect and magnetic balance, with galvanic isolation between primary and secondary circuit. The size of primary does not affect test precision, no matter the location of primary in the hole of the current sensor. It can truly distinguish the measurement of 1000:1, accurately measure DC, AC, pulse and various irregular waveforms under the condition of electrical isolation.

With more than 12 years experience in current measurement field, Cheemi offers innovative, high quality voltage sensors with much competitive prices to meet the customers' needs. OEM/Customize unique sensors for your special application requirement is available!

Our sensors are alternative to LEM, Tamura transducers. Free samples are available for your testing and evaluation before purchasing.
