this Temperature Transmitter is a microprocessor-based, two-wire device for converting various mV and ohm type sensors into a linear 4 to 20 mA or digital output. A standard two-wire system provides a nominal 24 V dc power to the transmitter and also carries the output signal to a receiver tied into the loop wiring. There are three different output types with communications capabilities as follows:
- Output Code -I: 4 to 20 mA without remote communications
- Output Code -T: 4 to 20 mA output with HART communication
- Output Code -D: 4 to 20 mA or FoxCom™ digital communication
The microprocessor-based transmitter has been designed to accept a wide variety of mV and
resistive sensors:
- Thermocouples
- RTDs (2, 3 or 4 wire)
- Millivolt dc sources
- Resistive Sensors (Ohms measurement)
- Dewpoint Sensors (Foxboro Model 2781)
