Disassembly

WARNING
Incorrect disassembly
The following dangers may result through incorrect disassembly:
- Injury through electric shock
- Danger through emerging media when connected to the process
- Danger of explosion in hazardous area
In order to disassemble correctly, observe the following:
Before starting work, make sure that you have switched off all physical variables such as pressure, temperature,
•
electricity etc. or that they have a harmless value.
If the device contains dangerous media, it must be emptied prior to disassembly. Make sure that no environmentally
•
hazardous media are released.
Secure the remaining connections so that no damage can result if the process is started unintentionally.

Installation instructions

Requirements
Note
Compare the desired operating data with the data on the nameplate.
Please also refer to the information on the remote seal if this is fitted.
Note
Protect the pressure transmitter from:
Direct thermal radiation
•
Rapid temperature fluctuations
•
Severe soiling
•
Mechanical damage
•
Direct sunlight
•
The installation location is to be as follows:
● Easily accessible
● As close as possible to the measuring point
● Vibration-free
● Within the permitted ambient temperature values

Installation configuration

The pressure transmitter may in principle be configured above or below the pressure tapping point. The recommended
configuration depends on the aggregate state of the medium.
Installation configuration for gases
Install the pressure transmitter above the pressure tapping point.
Lay the pressure tubing with a constant gradient to the pressure tapping point, so that any condensation produced can drain
in the main line and thereby avoid corruption of the measured values.
Installation configuration for vapor and liquid
Install the pressure transmitter below the pressure tapping point.
Lay the pressure tubing with a constant gradient to the pressure tapping point so that any gas pockets can escape in the
main line.
