What is your main concern/task to be solved?

SENIS provides miniature, PCB mount current sensors with a magnetic shield and high performance linear Hall sensor. The Bus Bar Current Sensors are made of two magnetic field sensors. Placed at opposite sides of a current bus bar they measure currents in the f-bandwidth between DC to >200kHz while beeing insensitive to external magnetic fields. The Clamp-On Closed-Loop Current Transducers allow the measurement of DC, AC and pulsed currents, with a unique total accuracy of better than 0.1%. SENIS clamp-on Microammeters can measure direct currents down to as low as 1 uA.

Clamp-On Open-Loop DC MicroAmmeter

The open-loop high sensitivity clamp-on Microammeters can measure direct currents down to 1 uA only. It can be used to indirectly measure and track leakage current through a fault in the insulation system of electrical machines. Measurement ranges 10mA to 10A. The MicroAmmeter is a clamp-on toroidal ferro-magnetic core with an air gap, in which the AMR sensors of a differential Hall magnetometer is inserted. The system includes a demagnetization circuit for the ferro-magnetic core and a PC software for data acquisition and visualization.
