5. Description
5.2.2.1 Probe Extension Cord
Based on the fact, that the AS-active-probes are active probes, whose
electronic outputs a calibrated voltage signal related to the measured flux
density, a probe extension cord can be inserted between AS-active-probe
and Teslameter FM 302, AS-Adapter 3 or PLC without negative influence on
the measuring signal. So even wider distances between measured object
and measuring device can be bridged.
Appropriated extension cords are optional available in different lengths.

AS-Probe Adapter
The AS-probe adapter is designed to autonomously operate our AS-
active-probes without Teslameter.
As a result of the wide supply voltage range of 9 V
adapter may be used universal in different system configurations.
Furthermore the AS-probe adapter galvanically isolates the power supply
from the probe supply and the measuring electronic.
The AS-probe adapter provides high stable ±3 V necessary to supply the
AS-active-probes. To ease the connection of the AS-active-probe to existing
analog inputs with ±10 V input range, the AS-probe adapter contains an
integrated amplifier. This amplifies the output signal of the AS-active-probes
from ±2 V to ±10 V. With a switch, an additionally 10times higher gain can
be chosen which allows to perform even sensitive measurements.
The analog output of the adapter is calibrated and thus can be used e.g. for
displaying magnetic pulses in the µs-range (oscilloscope), recording of
measurements and for field control. The bandwidth of the analog output
reaches from DC to a least 100 kHz. Therefore it is suitable for measuring
both constant magnetic fields and alternating magnetic fields.
Included in delivery is an adapter cable which allows the easy connection of
the 15-pole SubD connector of the AS-active-probes with the screw
terminals of the AS-probe adapter.
