The new TPK 21 LT is intended to be used to measure the pressure dew points, pressure
and temperature of clean, oil-free compressed air, which is free of any abrasive,
corrosive, caustic, toxic, flammable and combustible components. For the scope of
application and the calibrated measuring range, please refer to the technical data.
In the industrial sector, quality requirements for compressed air are becoming ever stricter.
Humidity and condensation are not permitted in compressed air and often cause damage to
machines and lead to reduced production quality. Compressed-air dryers are commonly used.
When used correctly, these reduce the moisture content of the air and ensure the production
of high-quality compressed air.
However, problems with dryers are often detected very late on, usually when damage has
already occurred. A large quantity of humidity will have already entered the compressed-air
network, and considerable efforts will be required to dry the system out again. The high
quality standards of the industrial sector call for continuous, reliable and stable long-term
monitoring of the humidity content. This is the only way to detect problems early, before any
damage has occurred.
With its large measuring range, the new TPK series is the ideal measuring system for
monitoring refrigeration, adsorption and membrane dryers. The device is primarily intended
for stationary applications but is also suitable for use as a portable measuring
device thanks
to its simple connection system.
If compressed air is not dried before being fed into the compressed-air network, significant
quantities of condensate can form in the pipe network, resulting in the malfunctioning of
valves and pneumatic components, ultimately leading to loss of production. The pressure dew
point in compressed-air systems is therefore a key factor in determining air quality and should
be measured in all systems.
The new TPK series offers the ideal device for monitoring compressed-air quality (humidity,
pressure and temperature) and giving timely warning, before any damage has occurred.
The series has a built-in measuring chamber with a protection filter and filter choke, as well as
a plug connection for a 7.2 mm NW compressed-air socket. Power is supplied via the mains
adapter provided. Initial set-up of the measuring system therefore requires no interference
with the compressed-air network, nor any electrical installation work. Alternatively, the
measuring system can be installed on the compressed-air line to avoid the loss of scavenging
air.
