• Full PVDF body for long sensor lifetime.
• Hermetically sealed electronics to prevent water ingress.

Operating Limits

• Measuring range: up to 12 m (39.37 ft) (with 40 mm antenna and flooding protection tube accessory)
• Process temperature: –40 to +60 °C (–40 to +140 °F)
• Process pressure: –1 to 3 bar gauge (–14 to 43.5 psi gauge); absolute pressure < 4 bar (58 psi)
• Ambient temperature range (device): –40 to +60 °C (–40 to +140 °F)
• Storage temperature: –40 to +80 °C (–40 to +176 °F)
• Operating altitude: Generally up to 2,000 m (6,600 ft) above sea level.

Feed Water / Process Medium

• Dielectric constant (εr): ≥ 4 for liquids. Contact Endress+Hauser for lower εr values.

Product Water / Measured Variable

• Measured variable: Distance from reference point to product surface. Level is calculated based on the entered empty distance.
• Accuracy (typical, under reference conditions):
  • Digital (SmartBlue): ± 5 mm (±0.2 in) sum of non-linearity, non-repeatability, and hysteresis; ± 4 mm (±0.16 in) offset/zero point.
  • Analog (4-20mA): ±0.02 % span (linearity, repeatability, hysteresis); ±0.03 % span offset/zero point.
• Measured value resolution (dead band): 1 mm (digital), 4 µA (analog).
• Response time: < 3 s (tank height < 5 m, damping off).

Electrical

• Supply voltage: 10.5 to 30 VDC
• Power consumption: Max. 675 mW
• Current consumption: Max. < 25 mA; Max. start-up current 3.6 mA.
• Output signal: 4 to 20 mA (analog)
• Digital output: Bluetooth® wireless technology (for SmartBlue app)
• Alarm signal: 22.5 mA (current output, in accordance with NAMUR NE 43)
• Integrated overvoltage protection.

Mechanical / Hydraulic

• Ingress protection: IP66/68 / NEMA 4X/6P
• Antenna size: 40 mm (1.5 in)
• Process connection: G 1 1/2", NPT 1 1/2" (also other sizes available via accessories like flanges)
• Body material: Full PVDF construction.
• Weight: Approx. 3.0 kg (6.6 lb) (including 10 m cable).
• Standard cable length: 10 m (33 ft); extendable up to 300 m (984 ft) total length.

Environment
