Honeywell’s microprocessor based STT350 Smart Temperature Transmitter converts a primary sensor input into an output signal for a conventional 4 to 20mA, two wire loop. This universal temperature input model readily accepts signals from a wide variety of industry standard thermocouples or resistance temperature detectors (RTDs) as well as a straight millivolt or Ohms sensor. Its output signal is either proportional to the measured variable or linearized to temperature, and is transmitted in either an analog 4-20mA format or a digital DE protocol format for direct digital integration to the TPS® control system. You easily select the analog or digital format for the output signal transmission through the Smart Field (SFC) which is the common hand-held operator interface for our Smartline™ Transmitters. All configuration, operation and communication functions are under the control of the STT350’s microprocessors and are implemented through the SFC.
