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 press ure acts on the sensor element via the stainless
steel diaphragm. The process pressure causes a resistance change
which is converted into a corresponding output signal and outputted as
measured value.
1)
Two-wire electronics 4 … 20 mA for power supply and measured
value transmission over the same cable.
The supply voltage range can differ depending on the instrument
version. The exact range is stated in chapter "Technical data".
The background lighting of the indicating and adjustment module is
powered by the sensor. A certain level of operating voltage is required
for this. You can find the exact voltage specifications in chapter
"Technical data".
3.3 Operation
IPT-1* can be adjusted with different adjustment media:
l with indicating and adjustment module
l the suitable WIKA DTM in conjunction with an adjustment software
according to the FDT/DTM standard, e.g. PACTware and PC
l with manufacturer-specific adjustment programs AMS™ or PDM
l With a HART handheld
The entered parameters are generally saved in IPT-1*, optionally also
in the indicating and adjustment module or in PACTware.
1)
Measuring ranges up to 16 bar: piezoresistive sensor element with internal
transmission liquid. Measuring ranges up to 25 bar: strain gauge (DMS)
sensor element on the rear of the stainless steel diaphragm (dry).
