• Linearized temperature measurement with TC and RTD sensors e.g. Pt100 and Ni100.
• HART communication and 4 to 20 mA analog PV output for individual, difference or average temperature measurement of up to two RTD or TC input sensors.
• Conversion of linear resistance to a standard analog current signal, e.g from valves or Ohmic level sensors.
• Amplification of bipolar mV signals to standard 4 to 20 mA current signals.
• Up to 63 transmitters (HART 7) can be connected in a multidrop communication setup.
Technical Characteristics
• HART protocol revision can be changed by user configuration to either HART 5 or HART 7 protocol.
• The HART 7 protocol offers:
     • Long Tag numbers of up to 32 characters.
     • Enhanced Burst Mode and Event notification with time stamping.
     • Device variable and status mapping to any dynamic variable PV, SV, TV or QV.
     • Process signal trend measurement with logs and summary data.
     • Automatic event notification with time stamps.
     • Command aggregation for higher communication efficiency.
     • TXUN-HT is designed according to strict safety requirements and is therefore suitable for applications in SIL installations.
     • Continuous check of vital stored data. Meeting the NAMUR NE 21 recommendations, the TXUN-HT HART transmitter ensures top measurement performance in harsh EMC environments. Additionally, the TXUN-HT meets NAMUR NE43 and NE89 recommendations.
• For DIN form B sensor head mounting.
• Configuration via TXUN-KIT for standard set up or via HART programming unit for Hart Communication set up. See links in Notes.
