5.2.2 Excessively high temperature of the medium
EXCESSIVELY HIGH TEMPERATURE OF THE MEDIUM
• Verify that the temperature of the medium does not exceed the permissible
operating temperature of the product.
Failure to follow these instructions can result in death, serious injury or
equipment damage.
Install a siphon or a chemical seal to help protect the product from the
hot medium.
5.2.3 Corrosive media
CORROSIVE MEDIA
• Verify that all components of the product that come into contact with the
medium are compatible with the specified materials.
Failure to follow these instructions can result in equipment damage.
The described products may be used if corrosive media can be kept away
from the measuring element by means of separating elements.
If this is impossible, the material most suitable for the medium to be meas-
ured and its pressure must be selected.
1. Provide the manufacturer with all information on the materials that are
compatible with the medium to be measured under the specific meas-
uring conditions.
2. If the materials of the elastic measuring elements of the Bourdon tube
pressure gauges are not sufficiently resistant to the medium, use a
chemical seal upstream the Bourdon tube pressure gauge.
