HSU-Series Hall Sensors
This model features unpackaged mounting construction on a ceramic plate. The active sensing area of the sensor is 100 X 100 um. This allows one to make hall effect measurements in areas not previously accessible due to the size of commonly available packaged sensors.
HSP-Series Hall Sensors
This model features transverse mounting construction in a sturdy epoxy filled package. High linearity of the hall voltage versus magnetic field and small temperature dependence of sensitivity sets this sensor apart from commonly available hall effect sensors.
This model features axial mounting construction. Hall voltages are guaranteed to be at least 10 mV per Tesla. This represents a 25% increase in sensitivity over sensors previously offered.
Cryomagnetics Model GM-700 Hall Effect gaussmeter easily interfaces with the above Hall effect sensors.
