RTD Resistance Splitter-Isolator PTi1000_DH/SH/XD

How to read single RTD sensor on two systems? This is how:

the PTi splitter-isolator is used in temperature control systems to split the signal from a single RTD to multiple independent resistance-based measuring systems. Providing full galvanic isolation applied to every port (in/out/power) avoids measurement error due to ground coupled impedance and ensures intrinsic safety separation in explosion risk environments. Special, patented design delivers high accuracy, real-resistance-outputs as RTD sensor-repetition even on pulsed measuring systems, regardless of excitation current or read-pulse duration. Input sensor 4-wire, 3-wire and 2-wire with line-loop compensation connections are supported.

The device is designed for sensor-sharing (i.e. RTD splitter), isolating and conversion between RTDs such as PT100/1000/KTYxx, position detectors, force sensors, etc. For various applications several types are available: Full-Auto-range, several Narrow-range types, RTD + Current & Voltage output; modular – multiple RTD-resistance outputs type and also as Current/Voltage to RTD converter for simulating RTD resistance.
