E+H Turbimax CUS71D Smart Ultrasonic Sludge Level Sensor
CUS71D-AA1A
Engineered for precise continuous monitoring in municipal and industrial wastewater treatment, the CUS71D Smart Ultrasonic Sludge Level Sensor delivers highly accurate, real-time interface and sludge blanket measurement up to 10 meters. Featuring robust IP68 submersible construction, digital Memosens signal technology for noise-free transmission, and an optional automatic wiper system to eliminate biofouling, this sensor optimizes sludge pumping schedules, prevents solid carryover, and ensures uninterrupted, low-maintenance operation in settling tanks, clarifiers, and thickeners worldwide.
The CUS71D Ultrasonic Sludge Level Sensor represents an advanced digital solution designed for high-reliability continuous monitoring of sludge blankets, interface zones, and separation levels within primary, secondary, and tertiary clarification systems. Utilizing precise ultrasonic return-time measurement technology, this intelligent immersion sensor emits focused acoustic pulses downward through the liquid column to accurately locate the exact position of the sludge interface layer, enabling automated control of desludge pumps, optimizing coagulant dosing, and safeguarding downstream filtration processes against solid carryover.
Designed specifically for demanding industrial and municipal environments, the sensor body is constructed from durable ABS and epoxy resin enclosed in an IP68-rated housing that comfortably withstands continuous underwater immersion up to 6 bar pressure. Integrated Memosens digital architecture processes and converts raw acoustic data directly within the sensor head, eliminating analog signal loss, interference, and cable degradation while storing all calibration data directly on board for true plug-and-play field commissioning. To guarantee continuous measurement integrity in organic or heavy-fouling wastewater applications, the sensor can be equipped with an optional maintenance-free EPDM automatic wiper that systematically cleans the ultrasonic transducer face, preventing algae buildup, biological film accumulation, and gas bubble adhesion.
Whether installed in circular clarifiers, rectangular settling tanks, thickeners, or drinking water treatment sedimentation basins, the CUS71D seamlessly connects with multi-channel controllers and universal industrial fieldbuses, providing plant operators with an efficient, durable, and highly cost-effective instrumentation asset that drastically reduces manual maintenance requirements while maximizing operational process security.

Frequently Asked Questions
Q1: How does the automatic wiper system benefit my plant?
A: The auto-wiper periodically sweeps the piezoelectric transducer surface to remove algae, biological film, and air bubbles. This reduces routine manual maintenance by up to 90% and ensures accurate measurement even in heavy bio-fouling conditions.
Q2: Can the CUS71D sensor work with standard PLC systems directly?
A: The CUS71D uses a digital Memosens signal. It is connected to a multi-channel controller (such as the Liquiline CM442/CM444 transmitter), which then outputs 4-20mA, HART, Modbus RTU, Modbus TCP, or Profibus DP directly to your SCADA/PLC system.
Q3: Is field calibration required before operation?
A: No. The sensor comes pre-calibrated from the factory with calibration parameters stored directly in the sensor head. You only need to select the application profile on the controller during installation.
Q4: Do you offer OEM/ODM or compatible replacement models for system integrators?
A: Yes, as a professional industrial instrumentation manufacturer, we provide customized sensing solutions, alternative direct replacements, and full OEM services including custom cable lengths, mounting hardware, and branding.
