RTD
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.
