Length of connecting cable
Permissible cable length Lmax depends on the conductivity of the medium. A minimum conductivity of
20
µ
S/cm is required for measuring demineralized water.

In order to ensure measuring accuracy, moreover, comply with the following instructions when installing the
remote version:
• Secure the cable run or route the cable in a conduit. Movement of the cable can falsify the measuring signal,
particularly if the conductivity of the medium is low.
• Route the cable well clear of electrical machines and switching elements.
• Ensure potential equalisation between sensor and transmitter, if necessary.
Environment
Ambient temperature
Transmitter:
• Standard: -5 to +140°F (–20 to +60°C)
• Optional: -40 to +140°F (–40 to +60°C)
Note!
At ambient temperatures below -5°F (–20°C) the readability of the display may be impaired.
Sensor:
• Flange material carbon steel: 14 to +140°F (–10 to +60°C)
• Flange material stainless steel: -40 to +140°F (–40 to +60°C)
Caution!
It is not allowed to use the device beyond the min. and max. lining specified temperature values
(
→
“Medium temperature range”).
Note the following points:
• Install the device at a shady location. Avoid direct sunlight, particularly in warm climatic regions.
• If both fluid and ambient temperatures are high, install the transmitter at a remote location from the sensor
(
→
“Medium temperature range”).
Note!
HE or Harsh Environment Protection for sensor:
Provides enchanced moisture ingress protection for humid ambient environments. Apply in applications with
severe temperature cycling and humid environments. Refer to ordering information, page 38.
Storage temperature
• The storage temperature corresponds to the ambient temperature range of the transmitter and sensor
(see “Ambient temperature”).
• The measuring device must be protected against direct sunlight during storage in order to avoid unacceptably
high surface temperatures.
• Choose a storage location where moisture does not collect in the measuring device. This will help prevent
fungus and bacteria infestation which can damage the liner.
• Do not remove the protective plates or caps on the process connections until the device is ready to install.
This is particularly important in the case of sensors with PTFE linings.
