Electrohms (offers) support for all products in manufacture range at present and also provide customized products from the design stage to manufacture.
| Open loop current transducer Open loop current transducers measure ac and dc currents and provide electrical isolation between the circuit being measured and the output of the sensor (i.e the input current is measured without electrical contact with the primary circuit) providing galvanic isolation. These sensors are characterized by low cost, higher current measurement range in a given size and low power consumption. Generally preferred in battery-powered circuits given their low-operating power requirements |
Closed loop current transducers Closed loop current transducer measure ac and dc currents and provide electrical isolation. It offers fast response, high linearity, and low temperature drift. The current output of the closed loop current transducer is relatively immune to electrical noise. The closed loop current transducer is are also known as ‘zero-flux’ transducer since the secondary mmf nulls the primary mmf, by generating current in the compensating winding. Since the primary mmf and secondary mmf is equal and opposite in direction flux in the core will be zero. Closed loop current transducers are preferred when high accuracy and low temperature are essential. |
