Please read prior to installation!
Warning:
Do not exceed range of > 50 bar with standard versions.
With special version up to 350 bar.
Observe measuring ranges of sensor!
The probes are damaged if overheated.
Observe max. storage and transport temperature as well as
max. operating temperature
(e.g. protect measuring instrument from direct sunlight).
Warranty claims no longer apply if the instrument is opened,
in the case of inexpert handling or use of force.
Adjustments or calibrations should be carried out by qualified measurement
and control engineering staff only.
Important: Before installation shortly trail the compressed air in order to remove
condensate and particles. Prevents soiling the UDM 300.
Standing air leads to long measurement times.

Applications with compressed air always have one problem: humidity and conden-
sate. The high quality standards in the industry require a continuous humidity moni-
toring, which is reliable and long-term stable.
The
UDM 300
with its mesuring range from -80...+50°C
td
is the ideal measuring
system for
cold, adsorption and mebrane dryers
(please see scaling of output
signal, page 8 of technical data).
When installing the UDM 300 in compressed air plants, the pressure dew point
(dewpoint under pressure) is directly measured up to 50 or 350 bar. When installing
under atmospheric conditions (ambient pressure) or in the trailing area (expand air)
of compressed air plants, the atmospheric dewpoint is measured.
