PIECAL 511B
Ten Type RTD Plus Ω Simulator  


The PIECAL 511B simulates RTD resistances into all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition and computer systems.

The PIECAL 511B is a superior replacement for decade boxes, so there is no need to lug a decade box around or be prone to error by reading RTD tables incorrectly.

The PIECAL 511B has better accuracy and functions of many higher priced RTD calibrators.

  • Accurate to ±0.25°C (±0.5°F) for Pt 100 Ohm RTD’s with 0.1° resolution
  • Simulates 10 RTD curves with direct temperature output or Ω
  • Selectable °C or °F
  • Curves included for Platinum 100 and 1000Ω, Nickel 110 and 120Ω as well as for Copper 10Ω
    and 50Ω
  • Guaranteed to work with all pulsed instruments
  • Works with a wide variety of transmitters including popular Rosemount and Honeywell models
  • Compatible with devices using pulsed excitation currents such as PLCs, DCS and recorders.
  • EZ-Dial™ knob with two dialing speeds makes adjusting output easy
  • EZ-Check™ switch can store settings for 0% and 100% span adjustments
  • Uses standard "AA" alkaline batteries
  • Superior battery life of 45 hours under typical continuous usage
  • Easy access to battery compartment
  • Lightweight and rugged with a solid feel
  • Small and tough
  • Protected to 60V
