Application areas
This probe is suitable for monitoring or regulation
of relative humidity of atmosphere, for example, in
green houses, winter gardens, store rooms,
terrains or in EDV-rooms. The measuring range of
the used probe element is right from 35% rH to
90% rH, The switching point can be adjusted with
a potentiometer in the evaluation electronics
(sensor switching module). The sensor element is
protected against dust and direct water contact
with a hydrophobic sinter cap of polyethylene. The
electronics, integrated in the probe housing,
linearises the measuring element and improves
temperature behaviour.
The measuring probe is intended for simple
applications e.g. in the field of building
instrumentation. Hence, the measuring probe is
not temperature compensated.
The humidity probe is suitable for connection to
Universal sensor switching module 156503/17/30,
which performs the evaluation and provides it as a
switching output through a potential free relay.
