4 Mounting
4.1 Application conditions
Before mounting, setup and operation, take note that the pressure
transmitter as well as the isolating system were selected according to
measuring range, version and material suitable for the process
conditions. The load limits must be maintained in order to guarantee
accuracy and operational life span.
Caution:
In dangerous substances such as e.g. oxygen, acetylene, combustible
or toxic products as well as in refrigerating plants, compressors, etc.,
the pertinent instructions must be observed in addition to the general
regulations.
Take note of the following issues in respect to the process and
ambient temperature:
l Mount the differential pressure transmitter in such a way that the
permissible process and ambient temperature limits are neither
underrun nor exceeded.
l
Take the influence of convection and heat radiation into account
l
When selecting the chemical seals, make sure that the fittings and
flanges are pressure and temperature resistant
l
For this purpose select the suitable material and pressure stage
l
Mount in such a way that plus and minus side have the same
ambient temperatures to keep the temperature influences low
Caution:
With a surface temperature of the vessel >100 °C the electronices of
VEGADIF 65 is heated up unnecessarily. This can cause damages or
a failure of the electronics.
The vessel must be isolated in a suitable way so that this can be
avoided.
