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 dialling 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 the battery compartment

  • Lightweight and rugged with a solid feel

  • Small and tough

  • Protected to 60V
