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, 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 ground equalization between the sensor and transmitter, if necessary.
Environment
Ambient temperature
Standard: -5° to +140°F (-20° to +60°C) for sensor and transmitter
Optional: -40° to +140°F (-40° to +60°C)
Note the following points:
•
Install the device at a shady location. Avoid direct sunlight, particularly in
warm climatic regions.
•
If both medium and ambient temperatures are high, specify the remote
transmitter (refer to the “Medium temperature” ranges).
•
At ambient temperatures below -5°F (-20°C), the readability of the display may
be impaired.
15° to + 120°F (-10° to +50°C), 70°F (20°C) is the preferable storage 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 helps prevent mold, fungus and bacteria from damaging the liner.
•
Do not remove the protective plates or caps on the process connections until the
device is ready to install.
•
Standard: NEMA 4X (IP 67) for transmitter and sensor
•
Optional: NEMA 6P (IP 68) for Promag W sensor, remote version
