(-34 °C ≤ Ta ≤ +70 °C), IP65
V ≤ 42.4V, I ≤ 23 mA
Specific Conditions of Use (X):
1. The Model 5408 Level Transmitter will not pass the 500Vrms dielectric strength test
between the circuits and the earth ground. This must be taken into account during
installation.
2. Plastic wire-on tag, Plastic part of Process Seal Antenna and Non-standard paint
options (paint options other than Rosemount Blue) may cause risk from
Electrostatic discharge. Avoid installation that could cause electrostatic build-up,
and only clean with a damp cloth.
3. Cable entries must be used which maintain the ingress protection of the enclosure
to at least IP65. To maintain the ingress protection ratings, Covers and Sensor
Module to be fully tightened and PTFE tape or pipe dope is required for cable entries
and blanking plugs. See Instruction Manual on application requirements.
4. The applicable temperature class, ambient temperature range and process
temperature range of the equipment is as follows:
