Operating Instructions, 01/2009, A5E00295894-05
Heat Safety
Some metal parts and piping placed near the sensors are at elevated temperatures. The
reason is high temperature purging - either from steam or from air.
CAUTION
The sensors are designed for work at elevated temperatures, particularly when a purging
system is in operation. Even after operation these parts cool off slowly.
For any work around these sensors be sure to wear protective gloves.
If this rule is not followed serious burns of the unprotected skin may happen.
Pressure Safety
The sensor is tested at a pressure of 600 kPa. This pressure value should not be exceeded
in operational conditions.
WARNING
Should pressures higher than 600 kPa occur in the process, this can lead to destruction of
the sensors and their environment. In worst case process media may break free and pollute
the environment.
Avoid under any circumstances process pressures higher than 600 kPa.
If this rule is not followed, death, injuries and/or damage to property and environment can
occur.
Explosion Protection - II 1GD T135 °C EEx ia IIC T4 IP65
The LDS 6, with a central unit and sensors interconnected with optical fibers, is explosion
safe. Only a limited, low energy part of the electronics is located at the measurement site.
The distance between the central unit and the sensors can be several hundred meters. The
LDS 6 system is available in an Ex version and is then delivered with an approval for use in
hazardous environments. The ATEX certificate is a system certificate and is only valid if LDS
6 is installed according to the instructions given in the certificate.
