Simple installation
 Output Loop Powered isolators are popular because they don’t need auxiliary
power. Power comes from the controller input card.
A.C. Power
 The user’s cabling is kept simple.
 The isolator output is 4-20mA.

Versatile temperature measurement
 Function are isolation and conversion / linearisation of
sensor signals
 In process applications (long cable lengths) Transmitter /
Convertor will be located as near the sensor as possible.
 Single model ITXPlus can be configured for any
temperature span within all the standard thermocouple /
RTD calibrations

User-defined linearisation
Bulk liquids are normally delivered and costed by
volume.
Inventory measurement is usually by level, which
is then converted into volume.
