SICK UP56-214178 Series Ultrasonic Level Sensor

Selection Notes

• Confirm the required measurement range, as UP56 models support various ranges up to several meters.
• Verify the output type needed — available options include analog (4–20 mA), 0–10 V, PNP switching or IO‑Link.
• Choose the correct process connection such as threaded G1 or immersion tube mount.
• Check the operating temperature and pressure limits of the chosen variant. Most models handle -25 °C to +70 °C and pressures up to 6 bar.
• In addition, ensure the body material matches the process media, with stainless steel or plastic/TPU options available.

Why Choose the Sick UP56 Series

• Non‑Contact Ultrasonic Measurement
Ultrasonic technology measures level without contacting the process medium. This reduces wear and maintenance compared to contacting probes.

• Pressure‑Resistant and Durable Transducer
The transducer features PTFE protection and can withstand pressures up to 6 bar, making it suitable for pressurized tanks and vessels.

• Versatile Outputs and Interfaces
The UP56 series supports a range of outputs, including 4–20 mA, 0–10 V and switching signals. Certain variants also feature IO‑Link for easy parameterization and diagnostics.

• Wide Application Range
Suitable for liquids, viscous media and abrasive bulk solids, the series addresses many process environments.

• Integral Display Option
Some models include a local display, enabling direct visual feedback of level values without external devices.

FAQ

Q: What measurement principle does the UP56 series use?
A: The series uses ultrasonic non‑contact sensing, transmitting sound waves and measuring time‑of‑flight to determine level.

Q: What outputs are available on these sensors?
A: Outputs include analog (4–20 mA and 0–10 V) and switching (PNP), and some variants support IO‑Link parameterization.

Q: Can UP56 handle pressurized tanks?
A: Yes. The PTFE‑protected transducer is designed to withstand pressures up to 6 bar, enabling use in pressurised systems.

Q: Where is this series commonly used?
A: It is widely used for continuous level measurement in tanks, reservoirs, process vessels and bulk storage, especially in chemical, water and manufacturing industries.
