Uson-31 Ultrasonic Level Transducer for Hazardous Applications
Uson-31 ultrasonic level transducer is designed for continuous liquid level measurement in industrial applications that need safe operation, reliable performance, and flexible installation. It is especially useful in hazardous locations where users need non-contact level monitoring and stronger protection for field equipment.
A key feature of this model is its separate installation design. The transducer and transmitter can be installed apart from each other. This makes the system more flexible in harsh environments and helps protect the electronics in demanding field conditions. The transducer supports IP68 protection, while the transmitter supports IP65 protection.
Non-Contact Ultrasonic Measurement with Stable Performance
The transducer sends high-frequency ultrasonic pulses toward the liquid surface. When the signal reaches the surface, it reflects back to the transducer. The device then calculates the distance based on the travel time of the ultrasonic wave. This non-contact method helps avoid mechanical wear and reduces maintenance during long-term operation.
Uson-31 ultrasonic level transducer offers three selectable measuring ranges: 5 m, 10 m, and 15 m. It also includes temperature compensation, which helps improve measurement accuracy under changing ambient conditions. In addition, a special echo-processing algorithm helps reduce false echoes and improve signal stability in practical field applications.
Flexible Communication and Durable Field Design
The device supports RS-485 communication, which makes real-time monitoring and system integration easier. It also supports convenient multilingual operation for different installation environments. For corrosive applications, the transducer can use PVDF material to improve resistance and durability.
The product is certified for flameproof enclosure explosion protection with Ex d IIC T6 Gb. Its EMC design also complies with IEC61000-4 and GB/T 17626.2 requirements for EFT, ESD, and surge performance. These features help the device maintain stable operation in demanding electrical and industrial environments.
Typical Applications
This ultrasonic level transducer is widely used for remote real-time liquid level control in petroleum, chemical, environmental protection, metallurgy, and mining applications. It also works well in sewage treatment plants, waterworks, open tanks, rivers, lakes, and reservoirs. In addition, it is suitable for corrosive and hazardous areas such as drainage pumping stations, sump pits, biochemical reaction pools, and sedimentation tanks.
