The RTT15S Temperature Transmitter is a microprocessor based temperature transmitter that uses HART communication protocol. In addition to thermocouples and 2, 3, or 4 wire RTDs, the unit can take in ohm and millivolt signals. The RTT15S is in an explosion=proof housing with optional display and optical buttons for local configuration. This unit is also available as a basic module that can be surface or DIN rail mounted. Basic configurations on the RTT15S is a snap! Take a look at our newest video HERE highlighting Schneider Electric’s Foxboro RTT15S Temperature Transmitter.
