SUGGESTED INSTALLATIONS

SHORT DISTANCE, INDOOR INSTALLATION
Due to the low current involved, a very high grade of insulation is
required.
A dry environment is needed in order to obtain a insulation level not
lower than 10 ohm.

This type of connection is very delicate and requires constant attention
to maintain proper operating conditions.
Conventional electrodes should be used in indoor applications only,
with a cable not longer than 10 m (33').
MEDIUM DISTANCE, INDOOR/OUTDOOR INSTALLATION
When an outdoor installation is required, to obtain accurate readings
at distances from 10 to 50 m (33‑165'), it is necessary to install a
transmitter.
Since the introduction of AmpHel
no longer a problem. You can now connect the meter directly to an
AmpHel electrode, saving the cost of a transmitter or expensive
®
coaxial cable.
The standard cable length for AmpHel
Additional lengths of regular cable up to 50 m (165'), can be installed
without special connectors.
AmpHel electrodes feature a built‑in a micro‑amplifier to boost the
®
signal, drastically reducing susceptibility to noise and drift.
The sealed electrode body can stand a moisture up to 100% RH without
any effect on the signal.
