2.2 Designated use
2.2.1 Application and media
The Deltabar FMD72 is a differential pressure transmitter for measuring differential pressure and
level in pressurized tanks. The device has two sensor modules, which measure the operating pressure
(High Pressure HP and Low Pressure LP). The differential pressure/hydrostatic level is calculated in
the transmitter unit. The sensor signal is transmitted digitally. In addition, sensor temperatures and
the individual process pressures present at the respective sensor modules can be individually
evaluated and transmitted. If the limit values specified in the "Technical Data" and the conditions
listed in the instructions and additional documentation are observed, the measuring device may be
used for the following measurements (process variables):
Measured process variables
• Pressure HP and Pressure LP
• Sensor temperature
Calculated process variables
• Differential pressure
• Level (level, volume or mass)
2.2.2 Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
►
For special fluids and fluids for cleaning, Hauser is glad to provide assistance in verifying
the corrosion resistance of fluid-wetted materials, but does not accept any warranty or liability.
2.2.3 Residual risks
Due to heat transfer from the process as well as power loss in the electronics, the temperature of
the electronics housing and the assemblies contained therein (e.g. display module, main electronics
module and I/O electronics module) may rise up to 80 °C (176 °F). When in operation, the sensor
may reach a temperature close to the medium temperature.
