For rough operating conditions the transverse probe is provided in a design
with brass protective tube (AS-LTM, AS-NTM). However they are thicker
than the AS-NTP 0,6.
The transverse probes AS-NTP-Flex and AS-NTP-Flex 0,6 are made with a
strip of very thin, extreme flexible and bendable material. They are qualified
to measure remarkable hard to reach locations and smallest air gaps.
Furthermore the probe carrier is temperature resistant up to 100 °C at the
AS-NTP-Flex and even up to 150 °C at the AS-NTP-Flex 0,6.
The probe AS-NCu-Wire is an extra thin sensor connected with very light
wires. Thus the probe is suited to measure at closed quarters and to mount
into complex measurement setups.
At very high demands to accuracy and temperature stability the probe
AS-NTM-2 may be used. Linearity error and temperature drift have been
highly reduced compared to the other probes.
The transverse high-temperature probe AS-NTP-Hot-05 is designed to
measure even at high temperatures up to 150 °C and at low temperatures
down to –40 °C. The probe itself and the probe cable are constructed to
permanently endure those temperatures.
The also available axial probes (AS-LAP, AS-NAP, AS-HAP) have a small
diameter and thus are suitable to measure fields in small coils.
With the axial AS-UAP probes particularly small fields can be measured with
a resolution down to one nano Tesla. Furthermore it has the facility to
compensate ±70 µT which for example provides the possibility to
compensate the earth magnetic field. So only differences are measured
which can be done with higher resolution.
The AS-UAP probe is available in two types. The AS-UAP GEO-X probe is
suitable for general measuring tasks while the AS-UAP Lot probe with their
special plummet housing with weighted tip is mainly suitable for measuring
the vertical component of the earth magnetic field.
All AS-active-probes can be used without the Teslameter as transducer at
an PLC, see section 6.4.12.2 Usage as Autonomous Transducer.
