Industrial sensors With over 25 years experience in measurement for railway equipment, Mors Smitt introduces a new range of sensors based on closed loop technology, to supply the industry market. These sensors allow measurement of all current waveforms, with high galvanic insulation between the primary and secondary circuits. Closed loop sensors The probe placed in the air gap of the magnetic circuit, provides a voltage proportional to this flux. The electronic circuit amplifies the signal from the primary current Ip or voltage Up flowing across the sensor and generates a current into the secondary...

Mechanical mounting • • • Any mounting position is possible Recommended fixing: by screws and flat washers The busbar (or cable) must be centred Precautions in electromagnetic environment Due to their principle of operation (measure of magnetic field by the Hall effect probe), closed loop hall effect current sensors can be sensitive to strong magnetic fields. It is recommended to avoid positioning them to close to high current power cables. Processing of the sensor output signal Standard codes of practice advise that, before the signal is processed, a low-pass filter adapted to the bandwidth...
