Key parameters
Measuring range
Transmitter for 1 or 2 ultrasonic sensors FDU90/91/91F/92/93/95; measuring range up to 45 m (148 ft) depending on sensor/medium; also open-channel flow
Accuracy
Per paired FDU sensor TI; transmitter provides linearization (≤32 points) and temperature-corrected time-of-flight
Output
1 or 2 active analog outputs 4–20 mA with HART (or 0–20 mA); 1/3/6 relays SPDT; PROFIBUS DP option
Supply
AC: 90–253 VAC 50/60 Hz ≤23 VA; DC option: 10.5–32 VDC ≤14 W (typ. 8 W)
Process connection
Transmitter only — sensors FDU* have process mounts; field housing or DIN-rail housing
Housing
Polycarbonate or aluminum field housing; DIN-rail housing
Fits ultrasonic level and flow calculation where you need an Endress+Hauser Prosonic S FMU90. Transmitter for one or two FDU90/91/91F/92/93/95 sensors with measuring range up to 45 m, 1 or 2 active 4–20 mA HART outputs, up to six SPDT relays and optional PROFIBUS DP on AC or DC supply.
Key advantages
- Sensors — 1 or 2 FDU90/91/91F/92/93/95
- Range — Up to 45 m (148 ft)
- Outputs — 1/2× 4–20 mA HART; relays
- Linearization — Up to 32 points
- Supply — 90–253 VAC or 10.5–32 VDC
Typical applications
- Open-channel flow.
- Tank / silo ultrasonic level.
- Dual-sensor level setups.
Selection guide
- FDU sensor type
- 1 vs 2 channel
- Field vs DIN-rail housing
Common mistakes
- Wrong FDU for range.
- Ignoring temperature compensation.
- No linearization for odd vessels.
When to RFQ / what to tell us
- Sensors/housing/I/O.
- Quantity, ship-to.
