1. General information
■The in-line process transmitter described in the operating instructions has been
designed and manufactured using state-of-the-art technology. All components are
subject to stringent quality and environmental criteria during production. Our manage-
ment systems are certified in accordance with ISO 9001 and ISO 14001.
■These operating instructions contain important information on handling the instrument.
Working safely requires that all safety instructions and work instructions are observed.
■Observe the relevant local accident prevention regulations and general safety regula-
tions for the instrument's range of use.
■The operating instructions are part of the product and must be kept in the immediate
vicinity of the instrument and readily accessible to skilled personnel at any time. Pass
the operating instructions on to the next operator or owner of the instrument.
■Skilled personnel must have carefully read and understood the operating instructions
prior to beginning any work.
■In case of a different interpretation of the translated and the English operating instruc-
tions, the English wording shall prevail.
■The general terms and conditions contained in the sales documentation shall apply.
■Subject to technical modifications.

2.1 Overview

Case head Sensor tube
Sensor housing Process connection
2.2 Description
The pressure in the sensor tube generates a signal which is processed by the integrated
evaluation electronics and converted into a current signal or a HARTsignal. This signal
can be used for the evaluation, control and regulation of the process.
The sensor tube is a base body that deforms under pressure load in a controlled manner.
This allows the principle of resistive pressure measurement to be used, in which the
pressure-dependent extent of the deformation is measured with 4 metal strain gauges.
If the sensor tube deforms under the influence of pressure, the strain gauges are also
deformed correspondingly. The electric resistance increases or decreases proportion-
ally to the deflection (elongation or compression).To accurately measure the resistance
change, the strain gauges are wired to a Wheatstone bridge.

2.3 Sensor monitoring
The integrated monitoring is used for the electrical signal transmission of the sensor
status. If the sensor breaks, the pressure in the evacuated chamber between the support
tube and the sensor tube changes. On a deviation of 100 mbar, a first electrical or digital
warning signal is issued. On a deviation of 300 mbar, another electrical alarm signal
follows.
Version with HART(4 ... 20 mA with HART®signal)
The instrument can communicate with a controller (master). Both the measured values of
the process and the alarm status are transmitted.
Version with current loop (4 ... 20 mA analogue signal)
If the sensor breaks, the instrument 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 main and additional display are displayed in the display and operating unit.
The settings for the main and andditional display are versatile. In the factory setting, the
main display shows the pressure value of the output signal and the additional display
shows the temperature at the sensor tube.
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 values
can be read irrespective of the mounting position.
The instrument may only be installed in horizontal or vertical pipelines.
