The ULS-53 Ultrasonic Level Sensor is a compact and reliable device designed for limit level measurement of liquids and semi-solid materials in industrial environments. This advanced sensor uses non-contact ultrasonic technology to measure levels accurately without direct contact with the measured medium. As a result, it performs exceptionally well in applications involving wastewater, sludge, suspensions, adhesives, resins, mash, and paste materials.

Non-Contact Ultrasonic Measurement

The sensor operates by transmitting ultrasonic pulses toward the surface of the measured material. These sound waves reflect from the surface and return to the sensor. The integrated electronic module calculates the time taken for the signal to travel and return, converting this data into an accurate level measurement.

Temperature compensation and signal averaging improve measurement stability and precision. This intelligent processing ensures consistent performance even in challenging industrial environments.

Flexible Output and Control Options with Ultrasonic Level Sensor

The ULS-53 provides flexible output configurations to suit various control systems. The device supports a PNP transistor output with open collector, capable of handling switching currents up to 300 mA. It also offers a two-state current output of 4 mA / 20 mA, which integrates easily with modern monitoring and automation systems.

Users can configure the sensor using two onboard buttons or a magnetic pen. Certain versions also support remote configuration through Modbus RTU communication, allowing convenient system integration.

Ultrasonic level sensor ULS – 53 is Designed for Industrial Environments

This ultrasonic level sensor performs reliably in open and closed tanks, sumps, drains, and open channels. The contactless measurement principle prevents contamination and reduces maintenance requirements. Optical indicators on the device provide clear RUN and STATE status signals, allowing operators to quickly confirm operating conditions.

For applications requiring higher echo sensitivity, a horn adapter can improve signal reflection. This feature makes the device suitable for difficult media such as foaming liquids or loose materials.

Safety and Durability

The ULS-53 sensor is available in versions suitable for standard environments and explosive atmospheres (Xi). It offers high accuracy up to 0.15%, resolution below 1 mm, and an operating temperature range from -30°C to +70°C depending on the model.

The sensor also provides high environmental protection ratings up to IP68, ensuring durability in demanding industrial conditions.

With its precise ultrasonic technology, flexible outputs, and robust design, the ULS-53 Ultrasonic Level Sensor delivers dependable performance for industrial level monitoring and automation systems.
