General safety precautions
The temperature transmitter may no longer be used when the label becomes illegible.
Intrinsic safety barriers with protection type „ia“ are to be used for connecting to the temperature
transmitters.
The seals and gaskets are to be checked to see that they function properly prior to mounting and at
regular intervals in keeping with the climatic conditions and the influence of the media, and to be
changed as needed. Replacement seals and gaskets can be obtained from HYDAC ELECTRONIC
GMBH. (Standard seal see technical data) This check is to be conducted at least every three years.
Ensure that the measured fluids are compatible with materials of the seals and the materials of the
temperature transmitter used. Similarly, the "Safety-relevant Data" specified in the certificate must
be adhered to.
For temperature transmitters with optional pressure measurement function
If used simultaneously in zones 0 and 1, the pressure membrane of the device serves as a partition
wall between zones 0 and 1. The thickness of this partition wall is generally
≤
1mm, and with a
nominal pressure ranging below 100 bar,
≤
0.2 mm. In order to ensure this partition function, the
compatibility of the measuring fluids with the used device materials is compulsory, as well as the
overload and bursting pressures must absolutely be complied with (further details, please see
"Technical Data").
The internal measurement membrane of the pressure transmitter is to be protected against
mechanical damage. This applies especially if the unit is used simultaneously in zones 0 and 1
equally zones 1 and 2
Please ensure sufficient sealing between the zones as well.
The data pertaining to use in Hazardous Location is to be heeded in any event.
Operation is only permitted if operational and process-related intensive electrostatic charges have
been eliminated.
When used in atmospheres containing combustible dusts, the temperature transmitter must be
installed in such a way that it is protected from damage and knocks.
By adherence to safety guidelines in the protection rating and applications:
