Proline t-mass 65 PROFIBUS DP Technical data
95
Cable entry Power supply and signal cables (inputs/outputs):
• Cable entry M20 x 1.5 (8 to 12 mm (0.31 to 0.47 inch))
• Threads for cable entries, ½" NPT, G ½"
Connecting cable for remote version:
• Cable entry M20 x 1.5 (8 to 12 mm (0.31 to 0.47 inch))

Cable specifications
(remote version) see Page 32
Power consumption AC:
85 to 260 V = 18.2 W ; 20 to 55 V = 14 W ;
(including sensor)
DC:
8 W
(including sensor)
Power supply failure Lasting min. 1 power cycle:
• EEPROM/HistoROM T-DAT saves measuring system data if power supply fails.
• HistoROM S-DAT is an exchangeable data storage chip with sensor specific data: (pipe type,
nominal diameter, serial number, flow conditioner, zero point, etc).
• Totalizer stops at the last value determined.
Potential equalisation No measures necessary.
For devices in hazardous areas please refer to the additional Ex documentation.
10.1.6 Performance characteristics
Reference calibrating
conditions • Accredited according to ISO/IEC 17025
• Traceable to National Standards
• Temperature controlled to within ±0.5 °C (±0.9 °F)
• atmospheric pressure
• humidity controlled
Maximum measured error Flanged version:
±1.5 % of reading for 100 % to 20 % of full scale at reference conditions
±0.3 % of full scale for 20 % to 1 % of full scale at reference conditions
Insertion version:
±1.5 % of reading plus ±0.5 % of full scale
!
Note!
• Calibration gas is normally air at reference calibration conditions and with a fully developed flow
profile.
• On site performance is dependent on the standard of installation.
Repeatability ±0.5 % of measured value for velocities above 0.2 m/s (0.65 ft/s)
Response time Typically less than 2 seconds for 63 % of a given step change (in either direction).
