Function
SITRANS FUS060 with HART
Operating Instructions, 09/2021, A5E01204521-AL
Flow by measuring the transit time difference of ultrasonic signals through ultrasonic
transducers in DN 100 to 4000 2-path sensor pipes (optional, depending on selected
size, 1-path or 4-path special solutions are possible)
2-path DN 100 to DN 4000 (optionally also 1-path and 4-path, depending on size (DN
25 to DN 4000))
120 m (395 ft) (shielded coaxial cable). For Ex version the transducer cable length is
restricted to 3 m (9.84 ft) in order to meet requirements for electrical immunity. For
2-path and 4-path systems with sizes ≥ DN 3000 cable length is restricted to 30 m
(98.4 ft).
4 to 20 mA active current output (13.2 V < open loop voltage < 15.8 V)
20 to 22.5 mA, adjustable
3.6 mA, 22 mA or 24 mA
≤ 600 Ω for non Ex version
≤ 330 Ω Ex version (HART ≥ 230 Ω)
Active: 24 V DC, ≤ 24 mA, Ri = 300 Ω
Passive: open collector, 30 V DC, ≤ 200 mA
Passive: open collector, 30 V DC, ≤ 100 mA
Pulse output
Adjustable pulse significance ≤ 5000 pulses/s
Adjustable pulse width ≥ 0.1 ms
Frequency output
f selectable up to 10 kHz
