3. Installation
Warning: • Installation instructions given in the following are to be observed in order
to guarantee a perfect functioning and a safe operation of the meter.
3.1 General information
3.1.1 Temperature ranges
Caution: • In order to prevent a damaging of the meter, you are requested to strictly
observe amplifier’s and detector’s maximum temperature ranges.
•
In regions with extremely high ambient temperatures, it is recommended
to protect the detector.
•
In cases where fluid temperature exceeds 100°C, foresee separate
amplifier and detector (separate version).
3.1.2 Protection class
In order to fulfill requirements in respect of the protection class, please follow the
following guidelines:
Caution: • Body seals need to be undamaged and in proper condition.
• All of the body screws need to be firmly screwed.
• Outer diameters of the used wiring cables must correspond to cable
inlets (for M20 Ø 5....10 mm). In cases where cable inlet is not used, put
on a dummy plug.
• Tighten cable inlets.
• If possible, lead cable away downwards. Thus humidity cannot get into
cable inlet.
We normally deliver the meter in accordance with protection class IP 67. If you however
require a higher protection class, the amplifier is to be installed separately from the
detector. If requested, we can also deliver the detector in IP 68.
