regulations and directives.The instrument must only be operated in a
technicallyawlessandreliablecondition.Theoperatorisresponsi-
ble for the trouble-free operation of the instrument. When measuring
aggressive or corrosive media that can cause a dangerous situation
if the instrument malfunctions, the operator has to implement suitable
measures to make sure the instrument is functioning properly.
During the entire duration of use, the user is obliged to determine the
compliance of the necessary occupational safety measures with the
current valid rules and regulations and also take note of new regula-
tions.
The safety instructions in this operating instructions manual, the na-
tional installation standards as well as the valid safety regulations and
accident prevention rules must be observed by the user.

beyond that described in the operating instructions manual may be
carried out only by personnel authorised by the manufacturer. Arbi-
traryconversionsormodicationsareexplicitlyforbidden.Forsafety
reasons,onlytheaccessoryspeciedbythemanufacturermustbe
used.
To avoid any danger, the safety approval markings and safety tips on
the device must also be observed and their meaning read in this oper-
ating instructions manual.

3.2 Principle of operation
IPT-2x is suitable for applications in virtually all industries. It is used for
the measurement of the following pressure types.
• Gauge pressure
• Absolute pressure
• Vacuum
Measured products are gases, vapours and liquids.
IPT-2x is especially suitable for applications with higher temperatures
and high pressures.
The IPT-2x is suitable for the measurement of the following process
variables:
• Process pressure
• Level
Application area

Fig. 2: Process pressure measurement IPT-2x
The process pressure acts on the sensor element via the process dia-
phragm.The process pressure causes a resistance change which is
converted into a corresponding output signal and output as measured
value.
Piezoresistive sensor element
Measuringrangesupto40bar:piezoresistivesensorelementwith
internal transmission liquid is used.
