The TruCurrent150 is a DC current sensor capable of measuring the DC amperage of an Anode Cell. It uses a Hall Effect magnetic sensor, which creates an output voltage in proportional to a magnetic field. When current flows in a conductor a magnetic field is generated.


Magnetic Sensitivity 20mV/ mT(typ.)
Operating Temperature Range, - 40 to 100 C
Supply voltage from 3.0V to 5.5V at single power supply
Ratio-metric analog output
Analog output which proportional to the magnetic field strength and pole
Toroid concentrates the magnetic field
Plastic housing
Limit AWG 22 transducer cable runs to 30 m (~100 ft), or larger AWG 20 wire
Spring loaded quick electrical connection
Hall Effect chip is potted in epoxy


Large opening can accom- modate many lugs without
Self-contained and does not require special mount- ing
Time saving installation
Works with C Cells & Box Cells
Small Size and Weight
Direction arrow points to Anode Cell.
Easy to attach wires.
