3.5 Installation
3.5.1 Sealing and screwing-in
Connecting shank G:
A flat gasket in accordance with DIN EN 837-1 is required for sealing.
NPT thread connection:
Seal the thread with Teflon or other similar permissible, resistant sealing material.
Process connection for special connections:
Information regarding the installation of variants with special connections is available from the
manufacturer on request.
3.5.2 Humidity
Use a suitable cable and tighten the cable gland in accordance with the recommended torque
specifications. Protect the transmitter from penetrating moisture by dropping the cable down
before the screw connection. Any liquids running along the cable will thus drip off before
reaching the screw connection; refer to
Laying electrical cables correctly on page 19. This is
particularly important for unprotected installation outside or in rooms in which moisture is an
issue (e.g. as a result of cleaning processes) or on cooled or heated containers.
CAUTION!
•
Prior to installing the transmitter it is essential to verify whether the version of the device on
hand completely fulfils the technical and safety requirements of the measuring point. This
applies in particular to the measuring range, overpressure resistance, temperature,
explosion protection and operating voltage.
• Check the materials used for the wetted parts (e.g. gasket, process connection, separating
diaphragm etc.) for suitability as regards product resistance.
