4.2.12 EQ LTE™ moisture data logger
4.2.12.1 Technical data
4.2.12.2 Sensor installation
Warning risk high pressure. Isolate
gas connection from the compressed
air system (e.g. gate or ball valve)
before attempting to locate the
moisture sensor
. Read and
understand all safety instructions
for both EQ LTE™ data logger
and the compressed air
installation and consider any risks
where the data logger will be
located before proceeding.
If in doubt stop immediately!
The sensor is supplied complete with
measuring chamber. The measuring chamber
features a quick release coupling.
Connect sensor and measuring chamber
assembly to the compressed using the quick
release coupling.
In case of compressed air containing oil and
dirt particles a pre-filter should be installed in
front of the measuring chamber.
Compressed air flows continuously in the
capillary pipe of the measuring chamber.
Note:
The location of the moisture sensor may
vary according to the parameter monitored.
Placing a moisture sensor in front and behind
a dryer allows evaluating a dryer’s
performance level.
