Process Inputs

The Tracker 200 digital panel meters and 300 series DIN rail of instrumentation for the measurement of process signals.

Industrial signals are loosely associated as process are 0-5VDC, 0-10VDC, millivolts DC and the most popular 20mA loops (e.g. 4-20mA). These are scaled as a range in engineering units e.g. 0-10VDC = 0-500 Litres Per Hour.

The Tracker Instruments that can accept ±20mA, ±10VDC and ±100mV are:

  • Tracker 211 4-Digit Low Cost
  • Tracker 212 5-Digit Low Cost with 4-20mA Linearisation
  • Tracker 220 Series 4/5-Digit High Accuracy + RS485
  • Tracker 250 5-Digit Melt Pressure Indicator + RS485
  • Tracker 300 DIN rail mounted + RS485.

All of the above have as standard or can be fitted as an option:

  • 10V and 24VDC sensor / loop excitation supplies (Standard all models)
  • Isolated Analogue output
  • Alarm Relays
  • Zero Function
  • Tare Function
  • Max/Min and reset

All the instruments listed above can also connect directly to thermocouples and RTD temperature sensors making their inputs "Universal"
