Current Sensors 

Sypris Test & Measurement/FW Bell manufactures a complete line of current sensors that accurately and cost-effectively measure current in a variety of applications. FW Bell has been a leader in this field for over 50 years, and continues to deliver some of the most precise sensors available. From our extremely accurate line of Magneto Resistive sensors to our cost effective open loop type, FW Bell produces a current sensor designed to meet the individual requirements of our customers.

Open Loop Current Sensors

Open loop current sensors measure DC and AC currents and provide electrical isolation between the circuit being measured and the output of the sensor. Typically, open loop current sensors cost less than closed loop sensors. They are preferred in battery powered circuits due to their low operating power requirements.

Closed Loop Current Sensors

Closed loop sensors measure dc and ac currents and provide electrical isolation. They offer fast response, high linearity and low temperature drift. The current output of the closed loop sensor is relatively immune to electrical noise. They are the sensor of choice when high accuracy is essential.
