Short Guide Pressure Transmitter
SAFETY NOTES
If the device is used incorrectly, application related dangers may arise.
The transmitter must be installed, connected, commissioned, operated
and maintained by qualified and authorised personnel only and un-
der strict observance of these operating instructions, relevant national
standards, legal requirements, and where appropriate, the product cer-
tification.
INSTALLATION
The function of the transmitter is nearly independent of its orientation.
To protect the process connection and pressure diaphragm from da-
mage, remove the protective cap just before installation. The pressure
transmitter must be installed in accordance with applicable national
guidelines for pressure components. We recommend the use of isolating
valves, syphons etc. During installation, ensure that no water enters the
housing. To orientate the valve connector, the union nut must only be
loosened slightly and the connector then rotated only 180° in each direc-
tion to avoid cable breakage.
INTENDED APPLICATION
The pressure transmitter is designed for measuring absolute and gauge
pressure of gases, vapours and liquids. Operation is only intended with
the specifications stated on the product label.
CLEANING
The measuring device is maintenance-free.
Certain media can cause build-up and clogging of the sensor. Accumu-
lated deposits can lead to incorrect measurements. In the case of media
that tend to form deposits, the sensor must be cleaned regularly, for
example with clear water. Do not use sharp or hard tools or corrosive
chemicals to clean the sensor.
