3.1 Intended use
3.2 General safety instructions
The protection of operating personnel and plant is not guaranteed if the
equipment is used for a purpose for which is was not intended.
The pressure transmitters LHC and PPC must only be operated by
authorised specialist personnel in accordance with these operating
instructions.
Observe the national safety and accident prevention regulations, as
well as the following safety instructions in this operating manual when
working with the pressure transmitters.
Do not carry out any operation on the equipment unless it is described
in the following instructions.
The connection of the devices and maintenance work under power
must only be carried out by a qualified electrical specialist.
If faults cannot be eliminated, the devices are to be taken out of
operation and protected against further unintentional operation.
Repairs must only be carried out by the manufacturer. Access inside
the device and modifications to it are not permissible and render the
guarantee null and void.
The operator is responsible for complying with local safety regulations.
Other important safety guidelines are located in the individual sections
of this instruction manual.

4 Product description
The pressure transmitters LHC und PPC can be used in level control as well as
pressure measurement in process applications. A variety of process connections,
measurement ranges, electronic interfaces and display options offer a product for a
wide range of applications.
4.1 Construction
The pressure transmitters consists of a pressure sensor, a control interface unit and
a housing cover with optional display. Different modular configurations are available
allowing a variety of designs (see model number key in section 12.1).

4.1.1 Pressure transmitter
The pressure transmitter has a piezo-resistive or thinfilm measurement cell (DMS)
depending on the pressure range. The sensors are temperature compensated, and
have a fully welded membrane which is "helium" leak-tested. Pressure transmitters
do not have internal seals.
Pressure transmitters further distinguish themselves from one another based on their
ranges and the types of media-touching materials. Different versions of process
connections can be selected for a wide range of application conditions.
The three main designs of pressure transmitters used in process applications are rod
type, rope type and externally mounted.
4.1.2 Control interface unit
The control interface unit contains the terminal compartment and the keypad used in
programming the device. The four keys must be active (unlocked) before use. The
keypad is locked during normal operation to protect data and functions previously
entered. The keypad automatically locks after 10 minutes of disuse. The control
interface converts the sensor’s digital signal into a standard 4 mA ... 20 mA current
signal.
Please note that rope type transmitters have a minimum bending radius
of at least 22 cm.

4.1.3 Display unit
The measured value indicator has four digits (in a 7-segment display) + symbols.
Below it, line 1 (16-segment display) is used to display error codes and the signal’s
unit of measure. The unit of measure can be selected by the operator.
Additional information is displayed in lines 2 and 3 (16-segment display). The operator
can enter commands in the programming mode on the display unit by means of menu
driven, clear-text prompts.
Devices with displays clearly offer a higher number of programming and control
interface options. These options include alarm status, dampening, signal inversion,
tank linearization and diagnostic messages
Display units can be easily upgraded (see section 6.2).

4.2 Function
The mode of operation for signal conversion is the same for all versions. The pressure
transmitter converts the existing pressure into an electrical signal. Microelectronics
further process the input signal and produce a proportional 4 mA ... 20 mA standard
signal.
The display-version allows programming (parameterization) and the display of
expanded functions such as inversion, dampening, alarm status and linearization.
4.2.1 Functions of devices without displays

4.3 Installation examples
The pressure transmitter LHC is primarily used to detect the hydrostatic pressure of
liquids in tanks. The measured pressure is provided as a height proportion or level
control signal. The pressure is measured using absolute (against a vacuum) or
relative (against external or air pressure) measurement depending on the type of
sensor selected.
Level control: Level control:
Externally mounted Combined pressure and head pressure
(with front flat diaphragm) are measured by two externally mounted
pressure transmitters. The two signals
are analysed and the differential is
calculated by a PLC or suitable signal
converter.
Level control: Level control:
Rope type suspended from top of tank. Rod type installed through top of tank.

The pressure transmitter PPC is also used for process pressure measurement within
pipes and containers.
Pressures between 20 mbar and 1000 bar can be measured, depending on the
measuring range selected. The pressure is either measured as an absolute value
(relative to a vacuum), or as a relative value (relative to atmospheric pressure).
Process pressure measurement: Process pressure measurement:
Used to measure pressure of liquids Used to measure container pressure.
or gases in pipelines
Process pressure measurement: Process pressure measurement:
Installed behind feed pumps for Units installed upstream and
process control or monitoring pump downstream of the filter. The pressure
differential is used to monitor the
function/accumulation of dirt in the filter.
Both output signals are processed by a
PLC or signal converter.
