ABB TTH300 Head mounted Temperature Transmitter

TTH300 - A NEW GENERATION OF HART TEMPERATURE TRANSMITTERS

The TTH300 HART features a multitude of new functions and enhanced diagnostic information. The temperature transmitter can be configured using the DSV401 (SMART VISION) device management tool or via FDT/DTM technology.

• Universal sensor input (RTD, thermo couple, Ohm, mV) 
• Various sensor error-calibration possibilities (one point, two point, Callendar- van Dusen) 
• Sensor Backup / autom. Sensor redundancy switching (2x Pt100 3-wire connection) 
• Freestyle characteristics (32 supporting points) 
• Output signal (temperature linear), 4...20 mA, HART signal 
• Accuracy 0.1 %, long-term stability 0.05 % per year 
• Unique new user friendly connection technology from the outside
