Real Resistance RTD Splitter/
Isolator PTi 1000 _DH/SH/XD/XS
High accuracy real resistance replicator & isolator PTi 1000_ is used for
galvanic isolation of resistance - based sensors and multiplying measuring
systems on a single sensor - i.e. RTD resistance splitter. Special, patented
design delivers high accuracy resistance output even when read on
pulsed or multiplex measuring systems.
Basic operation principle is resistance measurement, calculation and
resistance generation on two or more independent outputs. Mini OLED
display provides basic information on working mode, input resistance and
temperature correspondence for designated sensor. DIN rail mounted
housing is fitted for industry cabinet use.
For various applications a number of types are available: Full-Auto-range,
several Narrow-range types, RTD + Current & Voltage output, chained _DHf FEATURES
modules for multiple RTD outputs and Current/Voltage to RTD converter.
All with intrinsic safe galvanic separation on every port -see table below. RTD / Resistance 2, 3, 4w input
