Model 311A Universal RTD Calibrator 
The HOTTEST High Performance RTD Calibrator You Can Handle.

The new Model 311A sets the standard in handling pulsed excitation currents. This unit can read intermittent current pulses from Rosemount 3144 Smart Transmitters, multi-channel recorders, and DCS inputs down to 10 milliseconds. 
  • Universal Compatibility – Operates with devices that use pulsed excitation currents including PLCs, DCSs, and multi-channel recorders. Wide excitation current range (0.09 to 10.2 mA) for compatibility with most field instruments.
  • Simulate RTDs into Smart Transmitters – Works with a wide variety of models including Rosemount 3144 and Honeywell STT series.
  • Simulate and Read RTDs in C and F – Compatible with eight
    different platinum, copper and nickel sensors.
