Transverse Probe AS-NTP 0,6
Figure 42 Transverse probe 0,6
The transverse probe has a blue protective cap which have to be unscrewed
before measurement.
Utmost care and attention are needed if magnets have to be measured
that are not mechanically fixed. Clashing poles can destroy the Hall
element!
As the Hall element (ceramic) is very sensitive to pressure or shock,
mechanical stress must be avoided (risk of breakage)!

Transverse Probe Brass AS-NTM, AS-NTM-2, AS-LTM
Figure 43 Transverse probe brass
For fields of B > 20 mT and f > 10 kHz , probes brass should not be
operated for more than 1 min in order to prevent excessive heating of
the brass tube with the Hall element inside!
Attention should be paid to the fact that at the probe a connection exist
between GND, cable shield, plug housing and brass tube. Possibly an
isolated installation of the probe can be necessary to prevent an
unintended connection between measuring ground and protective
earth.
