  • Measure temperature using RTDs or Pt100 sensors, and voltage signals
  • Switch digital outputs
  • Monitor digital inputs
  • Count events
  • With extra hardware monitor thermocouples and strain gauge bridges
  • Control voltage or current outputs
  • Includes the powerful yet easy-to-use Windmill software for Windows: no programming required
  • Connect up to 8 USB units to one PC
  • Choice of analogue input ranges, selected with Windmill software individually for each channel
  • Alternatively, choose automatic ranging and let the software match the input signal as closely as possible
  • Integrating analogue-to-digital converter reduces electrical noise
  • Use Windmill to select the resolution of the A-D converter from 12- to 18-bits
  • Automatic recalibration
  • Comprehensive User Manual
  • Free technical support for life

RTD and Pt100 Sensors

Resistance temperature devices (or detectors) rely on the principle that the resistance of a metal increases with temperature. When made of platinum, they may be known as platinum resistance thermometers (PRTs), and when specified to have a resistance of 100 ohm at 0 oC, as Pt100.

Resistance measurements are made by passing a constant, known, current through the unknown resistance, and monitoring the voltage drop across the resistance. The 752 unit provides a constant current source of 1 milliamp. This gives excellent results for all wiring configurations, including 2 wire, 3 wire, 4 wire and 4 wire compensated. The most accurate results are obtained using a 4 wire arrangement.


Software

Chart Recorder Software
Windmill Charting software

Windmill software is included in the package. Windmill automatically converts the resistance measurement to a temperature in your choice of engineering units. data logging, charting, alarm indication, output control, process mimic generators, sequence control, programming tools and other applications.


Thermocouples and Strain Gauges

By adding a Microlink 593 unit, which provides cold junction measurement, you can also monitor thermocouples. For strain gauges you need a Microlink 594 connection box and excitation supply.
