Special conditions for safe use:
1. All transmitter models have external plastic parts, which could present a
risk of ignition due to electrostatic charge build-up. They shall not be
directly installed in any process where its enclosure might be charged by
the rapid flow of non-conductive media.
2. All transmitter models shall only be cleaned with a cloth.
3. When the transmitter housing uses aluminium alloy in its construction,
this presents a risk of ignition due to impact and shall be taken into
consideration on installation and use.
