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, foresee a
protection from direct sun radiation.
• In cases where fluid temperature exceeds 100°C, foresee separate
amplifier and detector (separate version).
Amplifier
Ambient temp. -20 to + 60 °C
Detector
Fluid temp. PTFE / PFA -40 to +150 °C
Hard rubber 0 to +80 °C
Soft rubber 0 to +80 °C
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.
