7.7 Chemical Environment
The materials used to construct the sonar process monitoring system
are resistant to damage from chemicals expected in target
applications.
If there are any known chemical agents in the intended installation
location that the installer believes may pose a special threat of
chemical attack on metallic or non-metallic materials, please consult
with Customer Support personnel prior to installation.
Notify Customer Support and, if necessary, take the affected
equipment out of service if routine inspections reveal the enclosures,
gaskets, or other system components are being chemically degraded
in their installed environment.
7.8 Mains Power
Mains power must be available at the transmitter location. Mains
power is not required at the sensor head location because it is
powered by low voltages created by the transmitter.
The mains power must be within the range of voltages and currents
required by the particular transmitter. The DC powered transmitter
(TB8–xx-06-xx-xx) requires voltage within the range of 18 to 36 VDC.
The AC powered transmitter (TB8-xx-05-xx-xx) requires voltage in the
range of 100 to 240VAC, 50 to 60Hz. Both types have a 25W
maximum input power rating and both have a requirement for power
quality with limited amplitude voltage spikes (see paragraph 3.1).
The mains power should wired per the applicable electric codes of the
facility in which it is installed and/or per the guidance of EN 60079-14.
Cable glands used should preserve the IP 55 and ATEX rating of the
enclosure. See paragraph 8.3.1 for information on the selection of
cable glands.
