January 24, 2012 - The Foxboro Model RTT80 Temperature Transmitter from Invensys Operations Management represents a new generation of transmitters that stand out due to their signal reliability, long-term stability, high precision and advanced diagnostics.
 
For demanding temperature measurement applications that require a rugged, robust and reliable temperature transmitter, the Invensys Foxboro RTT80 Temperature Transmitter is a mid-tier two-wire temperature transmitter available with HART, FOUNDATION Fieldbus and Profibus PA protocols, dual sensor inputs, dual compartment housing, diagnostics, alarms, RTDs and TCs. 

Key capabilities:

• Dual compartment housing isolates electronics from the terminal block for longer service life and better protection from corrosive environments;
• Intelligent hot-sensor backup switches to a secondary sensor in the event of a burn out, preventing unexpected downtime and loss of productivity;
• Corrosion measurement allows maintenance to better predict the quality of their temperature sensors and their life expectancy;
• Drift detection enables the control room to evaluate temperature measurements over time and make better decisions concerning sensor stability;
• Corrosion detection as per NAMUR NE89 prevents export of incorrect measured values and issues a warning via the HART protocol when conductor resistance values exceed plausible limits;
• Provides diagnostics according to NAMUR NE107.
