Solid Core Current Transducer Sentry 200 Series

Our Solid Core Current Transducer converts a monitored AC current to a proportional 4-20 mA output.

Applications:

They are used to monitor pumps, motors, conveyors, machine tools, and any electrical load where an analogue representation is required over a range of currents. All models are UL, ULC and CE listed.

Description:

The Sentry 200 Solid Core Current Transducer comprises a current transformer, power circuit, precision rectifier, high-gain servo amplifier, and span and zero adjustments. Each sensor has three user selectable ranges. The two wire loop powered 4-20 mA output is available on two 6-32 screw terminals.
