Temperature Transmitter
Electronics in the sensor head or in a field housing that turn the RTD or thermocouple signal into 4 to 20 mA or a digital signal.
What it does
Sends a clean, linear temperature signal to the flow computer and RTU over long cable runs without the errors of raw sensor wiring.
Basics
| Mount | Head mount or field mount |
| Inputs | RTD or thermocouple, single or dual |
| Output | 4 to 20 mA with HART, or digital |
