3.2 Principle of operation
IPT-1* is a pressure transmitter for measurement of overpressure,
absolute pressure or vacuum. Measured products are gases, vapours
and liquids in measuring ranges up to 4000 bar (400 MPa); with front-
flush version also viscous liquids in measuring ranges up to 600 bar
(60 MPa).
The process pressure acts on the sensor element via the stainless
steel diaphragm and an internal transmission liquid. This causes a
resistance change which is converted into a corresponding output
signal and outputted as a measured value. With measuring ranges
up to 16 bar a pieoresistive sensor element is used, with measuring
ranges from 25 bar a strain gauge (DMS) sensor element.
4 … 20 mA/HART two-wire electronics for voltage supply and meas-
ured value transmission on the same cable.
The supply voltage range can differ depending on the instrument ver
-
sion. The exact range is stated in chapter "
Technical data
".
The backlight of the display and adjustment module is powered by
the sensor. The prerequisite for this is a supply voltage at a certain
level. The exact voltage specifications are stated in chapter "
Technical
data
".
3.3 Operation
The instrument can be adjusted with the following adjustment media:
•
With the display and adjustment module
•
the suitable WIKA DTM in conjunction with an adjustment software
according to the FDT/DTM standard, e.g. PACTware and PC
•
With manufacturer-specific adjustment programs AMS™ or PDM
•
With a HART handheld
The entered parameters are generally saved in IPT-1*, optionally also
in the display and adjustment module or in PACTware.
3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
