Notes on safety
Approved usage The Barcon is a pressure transmitter for measuring gauge or absolute pressure
depending on the version.
Mounting,
commissioning,
operation
The Barcon has been designed to operate safely in accordance with current technical,
safety and EU standards. If installed incorrectly or used for applications for which it is
not intended, however, it is possible that application-related dangers may arise, e. g.
product overspill by incorrect installation or adjustment. For this reason, the instrument
must be installed, connected, operated and maintained by personnel that are authorised
by the user of the facility and who are suitably qualified. The manual is to be read and
understood, and the instructions followed. Modifications and repairs to the device are
permissible only when they are expressly approved in the manual.
Explosion-
hazardous area
The measuring system used in the explosion-hazardous area must comply with all
existing national standards. The instrument can be supplied with the following
certificates as listed in the table. The certificates are designated by the last letters of the
order code on the nameplate (see table below).
Ensure that technical personnel are sufficiently trained.
All measurement and safety regulations which apply to the measuring points are to be
observed.

Barcon LHC/PPC (HART)
Introduction

Date of Issue 25.10.2001
1Introduction
Application The Barcon PPC and the Barcon LHC pressure transmitter measures the pressure of
gases, vapours and liquids and is used in all areas of chemical and process engineering.
Operating principle
Ceramic sensor
The system pressure acts directly on the rugged ceramic diaphragm of the pressure
sensor deflecting it by a maximum of 0.025 mm (0.0098 in). A pressure-proportional
change in the capacitance is measured by the electrodes on the ceramic substrate and
diaphragm. The measuring range is determined by the thickness of the ceramic
diaphragm.
Metal sensor
The process pressure deflects the separating diaphragm with a filling liquid transmitting
the pressure to a resistance bridge. The bridge output voltage, which is proportional to
pressure, is then measured and processed.
Fig. 1.1: Sensor construction
Measuring system The complete measuring system consists of
• Barcon pressure transmitter with 4 mA … 20 mA signal output with
superposed digital signal (HART communication) and
• power supply 11.5 V … 45 V DC, in Ex area 11.5 V … 30 V DC.
Operation can be carried out via:
• a digital display for operating and calling up measured values locally,
• the universal handheld HART Communicator,
• the Pepperl+Fuchs PACTware operating program.
