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 splitt 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-restistance outputs type and also as Current/Voltage to RTD converter for simulating RTD resistance.

Features:

  • RTD in & RTD Out – resistance output,
  • superb accuracy of 0,02% (0,05°C /60°range  for PT100/1000),
  • 2, 3 & 4wire connection for input sensor and 2w line loop compensation,
  • pulsed (multiplex) measurement compatible,
  • conversion between PT100, PT 1000, KTYxx sensors,
  • RTD resistance + Current & Voltage out (SH type),
  • RTD simulation & signal from loop extraction (XD type),
  • modular-multiple RTD resistance out (DHf type),
  • OLED / NO-display version,
  • intrinsic galvanic separation on every port & Ex option,
  • 10 - 30V AC/DC single power supply.
