RTT80 I/A Series® Temperature Transmitter with FOUNDATION™ Fieldbus Communication Protocol
The RTT80 provides a wide range of packaging selections, sensor types, and options along with the FOUNDATION Fieldbus communication protocol, thus making this transmitter suitable for most temperature measurement applications. The microprocessor-based electronics minimizes ambient temperature effects and results in high accuracy, repeatability, and linearization of the sensor signal.
OVERVIEW
• For demanding temperature measurement applications that require a rugged, robust and reliable temperature transmitter, the Foxboro RTT80 Temperature Transmitter provides the best solution.
• The RTT80 is a mid-tier two-wire temperature transmitter available with protocols, dual sensor inputs, universal housing, diagnostics, alarms, RTDs and TCs. The RTT80 stands out due to signal reliability, long-term stability, high precision and advanced diagnostics (important in critical processes). For the highest level of safety, availability and risk reduction.
BUSINESS VALUE
• The rich diagnostics of the RTT80 enables cost savings via alarms to trigger predictive maintenance scenarios and is capable of automatically switching to a backup sensor and notify the control room that a primary sensor has gone bad. A failed temperature sensor can translate into major productivity losses.
EFFICIENT AND DURABLE
• Industrial-grade integrated circuits and sealed electronics combine to make this microprocessor-based transmitter an efficient and durable device.
RUGGED SENSORS
• The sensors are of high quality and rugged construction, and provide maximum accuracy and longevity. Sensors designed for use with thermowells include a spring loading mechanism that helps ensure continuous contact between the sensor tip and thermowell.
features
Intelligent “Hot Sensor Backup”
- • Should the primary sensor burn out, the RTT80 is able to intelligently switch to a secondary backup sensor. This prevents unexpected downtime and maintains productivity within the plant.
Sensor Corrosion
- • The RTT80 is capable of measuring corrosion on the Sensor. Maintenance is able to better predict the quality of their temperature sensors and their life expectancy.
Sensor Drift Detection
- • This diagnostic enables the Control room to evaluate their temperature measurements over time and make better decisions concerning sensor stability.
Automatic Temperature Range Sensor Change
- • The RTT80 is capable of switching the primary temperature measurement from sensor 1 to sensor 2 (a different sensor type) which is accurate for a certain temperature range.
Corrosion detection as per NAMUR NE89
- • The transmitter prevents incorrect measured values from being exported and can issue a warning via the HART protocol when conductor resistance values exceed plausible limits.
Sensor and Thermowell Attachment
- • The RTT80 can be mounted directly to Foxboro sensors and thermowells to provide reliable and dependable temperature measurement.
Calibration Scheduling
- • The RTT80 is capable of scheduling a future calibration time enunciation of up to 365 days. One enters a start date and then the number of days till next calibration for a maximum of 365 days.
