2.2 Description
The process transmitter built into the diaphragm monitoring system processes the
pressure prevailing at the process connection and converts it into a current signal or a
HARTsignal.This signal can be used for the evaluation, control and regulation of the
process.

Diaphragm monitoring
The monitoring element is used for electrical signal transmission of the diaphragm
condition. In addition, the diaphragm condition is displayed on a dial with red/green areas.
In the event of a diaphragm rupture, the pressure monitored in the intermediate space
increases. As soon as the display of the monitoring element exceeds the predefined set
point, an optical and electrical/digital alarm signal will be output.
Version with HART(4 ... 20 mA with HART®signal)
The diaphragm monitoring system can communicate with a controller (master). Both the
measured values of the process and the diaphragm status are transmitted.
Version with current loop (4 ... 20 mA analogue signal)
In the event of a diaphragm rupture, the diaphragm monitoring system transmits the
measured values via the current loop or the analogue error signal.
→ See chapter 10.8 “Alarm status of diaphragm monitoring” for signal processing within
the process transmitter
Measuring range scaling (turndown)
The start and end of the measuring range can be set within defined ranges.

Display and operating unit
The display and operating unit has a main and an additional display.
The main display and the additional display are able to be set in many ways. In the factory
setting, the main display shows the pressure value of the output signal and the additional
display shows the temperature at the pressure sensor.
The process transmitter can be configured via the display and operating unit.
Adaptable to mounting position
The process transmitter is fitted with a case head which can be turned through 330°.The
display and operating unit can be attached in 90° steps.Thus the measured value can be
read irrespective of the mounting position.

3. Safety
3.1 Explanation of symbols
DANGER!
... indicates a potentially dangerous situation in the hazardous area that can
result in serious injury or death, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result in serious injury
or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or
damage to property or the environment, if not avoided.
DANGER!
... identifies hazards caused by electrical power. Should the safety instructions
not be observed, there is a risk of serious or fatal injury.
Information
... points out useful tips, recommendations and information for efficient and
trouble-free operation.
3.2 Intended use
The diaphragm monitoring system described here is an instrument for measuring
pressure and, in addition, for monitoring the diaphragm condition.
Depending on the selected measuring range, the instrument can be used for measuring
gauge pressure/vacuum or absolute pressure.The physical quantity pressure is
converted into an electrical output signal. Depending on the selected version, the output
signal is “4 ... 20 mA with HART® signal” or a “4 ... 20 mA” current loop.
A double-diaphragm system ensures the separation of the process and the pressure
measuring instrument. In the event of a diaphragm rupture, the pressure monitored in
the intermediate space increases. As soon as the display of the monitoring element
exceeds the predefined set point, the alarm signal for a diaphragm rupture is transmitted.
Depending on the version, the alarm signal is output either via the HARTprotocol or as
an error signal on the current loop.
The measuring technology of the instrument withstands the process pressure despite
the diaphragm rupture.The measuring function of the process transmitter is maintained
without restrictions.
