The GM08, GM07 and VGM02 Gaussmeters are supplied with a transverse Hall probe (TP002) as standard.
The design of the Hall probe is critical to the satisfactory operation of any Gaussmeter. We have used our extensive industrial experience to produce a transverse Hall probe which is semi-flexible and only 1mm thick by 4mm wide. This enables operators to take measurements in tight spaces and narrow air gaps. In addition the sensitive Hall element is clearly visible so that the user knows exactly where the measurement is being made.
The probe is fitted with a push button enabling the operator to HOLD and STORE measurements and orientate the probe for polarity readings.
An axial probe is also available as an optional extra. This is only 5mm in diameter and also incorporates a push button for HOLD and STORE functions. The axial probe is encapsulated in a brass tube for strength. The tube has a slit to prevent the circulation of eddy currents in alternating fields.
All STANDARD transverse and axial probes are fully interchangeable on the GM08, GM07, GM05, GM04, VGM02 and VGM01 Gaussmeters without need for calibration. High sensitivity probes (HS) will only work on the GM07 and GM08
Various other transverse and axial probes are available and some of the most common options are shown in the diagrams. Transverse probes are available in thicknesses down to 0.6mm and axial probes are available in different lengths. It is also possible (as an option) to have longer cables fitted to the probes if required.
