High Precision Analog Hall Sensors

HE244 Hall Sensor Series

Leads

Ferrite core

Air gap

Hall Effect sensor

A common application is magnetic field measurements in thin airgaps

In the HE244 Hall sensor, the high resolution, combined with the ability to detect small changes in very strong magnetic fields, moves your measurements into the ppm range.

The HE244 hall sensor series is ultra-stable

Very wide range from a few µ-Tesla up to 10 Tesla and above
Measures both positive and negative fields with very high precision
Very low noise
Very wide temperature range; a high temperature version up to +250°C/+480°F is also available
Very low temperature coefficient
Very low offset
Ultra-low drift as well as long term drift
Ultra-low PHE (Planar Hall Effect) Error.

Z-field measurements show no X- and Y-field errors

X-ray resistant

For dynamic, low noise measurements, we recommend sensor currents of 2 mA or lower for the HE244. For higher output, sensor currents up to 10 mA can be used. As a rule of thumb, the HE244 series gives an output of 0,2 V/T at 2 mA sensor current.

Typical Applications:

Measuring precise homogenous fields
Precise current and power sensors
Measure both strongly magnetized metals and remanent magnetism with one sensor
Measurements in small metal, magnet and ferrite airgaps
Low DC current in strong AC currents, for example in windmills where only a limited DC current is allowed to be fed into the net
