Humidity-Temperature probe with
standard Signal FF-GLT-Series
Mounting of measuring probes
Mounting should be done with the probe tube in downside direction to
avoid mearuring error caused by self heating of the electronic circuit.
Moderate ow in region of the probe is an advantage concerning
response time and accuracy.
For mounting of external measuring probes, commercially available
bayonet connectors or mounting anges can be used. Please ask for
our accessories overview.
The probe is pressure tight up to 100 mbar. The probes are not suit-
able for compressed air with higher pressure.
For outdoor applications, a special weather protection housing with
mast/wall holder as well as a hydrophobic PE sinter lter is recom-
mended.
The projected measuring probe type -INT can be directly mounted on
the ventilation ducts. Drill the holes with the help of enclosed drilling
template, for the probe and two mounting screws. Directly mount the
probe on the ventilation duct with a gasket in between. Alternatively, a
mounting ange is available with clamping ring/clamping screws.

Product variants
Type -INT
The measuring probe is rmly anged on to the evaluation electronics.
Other probe tube lengths (max. 500 mm) are available on inquiry.
Type -EXT
The measuring probe is connected to the evaluation electronics
through a solidly mounted cable (approx. 1.5 m in stretched condi-
tion). The length L
B
of standard model is around 100 mm. Probe tube
length 150 mm and 200 mm are available at short notice.
Other lengths or special models e.g. pressure resistant humidity
probe with ½“ mounting threads are available on enquiry.
Type -AF
Model for wall mounting, for example, as external probe, the measur-
ing probe is horizontally anged (at the front side) to the evaluation
electronics. Probe tube length is around 70 mm.
