MARKINGS

The following explains the hazardous area markings that can be found
on the equipment.
2.1 Transmitter [TB8-xx-xx-xx-03] for use with Sensor Head
[SH-xxx-xx-xA-xxx-03]:
DEMKO 07 ATEX 0608105X
This particular model of transmitter can be installed in a safe area or
an area that is classified as an Equipment Group II (not in mines),
explosive gas (not explosive dusts or fibers), ATEX Zone 2 location
with explosive gas group IIA or IIB. Its enclosure has been tested to
IP55 (the second-to-highest dust rating and the rating for low-pressure
water jets). It is intended for an operating ambient air temperature
range of -20 ºC to +57 ºC. If installed properly, it will not produce a
hot-spot temperature in excess of 135 ºC during normal operation.
The transmitter includes certain energy-limited interfaces (see list to
determine which interfaces are energy-limited) that allow wires from
these interfaces to be routed in Zone 2 areas with a reduced
possibility of explosion. This, for example, permits the convenience of
being able to disconnect the sensor head cable connector from the
sensor head cover with the power ON with a reduced risk of
generating a spark with sufficient energy to trigger an explosion if an
explosive atmosphere happens to be present.
Note: In Zone 2, explosive atmospheres are not expected to be
present except under fault conditions. If the operator is aware that a
fault condition exists at the facility that makes it likely that an explosive
atmosphere is present, then extra caution is indicated.

Sensor Head [SH-xxx-xx-xA-xxx-03]:

-40C<=T
ONLY TO BE USED WITH TRANSMITTER TB8-xx-xx-xx-03
FOR ATEX MARKING SEE LABEL ON TB8 TRANSMITTER
This particular model of sensor head can be installed in a safe area or
an area that is classified as an Equipment Group II (not in mines),
explosive gas (not explosive dusts or fibers), ATEX Zone 2 location
with explosive gas group IIA or IIB. Its enclosure has been tested to
IP55 (the second-to-highest dust rating and the rating for low-pressure
water jets). It is marked for an operating ambient air temperature
range of –40 ºC to +100 ºC.
The +100 ºC rating relates to the safety aspect only and is intended to
include the effects of heating from the pipe on which it is mounted. To
