Dayu Electronics: Case Study on Frequency Testing of Clamp-On Level Gauge Transducer
Recently, the company received a clamp-on level gauge product of another brand sent by a customer, hoping to use the Dayu Electronics M33 clamp-on level sensor to professionally measure the working frequency of its core component—the ultrasonic transducer. This is not only a trust in Dayu Electronics' testing technical capabilities, but also a recognition of the M33 sensor's professional depth in the level detection field.
The M33 clamp-on level sensor operates on the ultrasonic reflection measurement principle. The sensor (transducer) emits ultrasonic signals, which penetrate the container wall and propagate through the internal medium. When the ultrasonic wave encounters a gas-liquid or liquid-liquid interface, a strong reflected echo is generated due to significant changes in acoustic impedance. The sensor determines the level state by analyzing the characteristics of the echo signal. This product is mainly used for oil level detection in transformer oil tanks. The sensor is mounted on the external wall of the oil tank, requiring no drilling or hot work, completely eliminating the oil leakage and contamination risks common with invasive instruments, while also reducing operator exposure to high-voltage equipment, effectively enhancing operational safety.
In the demanding scenarios of intelligent transformer operation and maintenance, the M33 sensor can continuously output liquid level data with millimeter-level accuracy. Combined with intelligent echo algorithms, it can filter out wall interference and operational fluctuations, achieving measurement accuracy of ±1mm to ±2mm. The sensor is suitable for stable operation in a wide temperature range from -40°C to +80°C, and features strong vibration resistance, adapting to various complex industrial sites.
The transducer is the core component of the clamp-on level gauge, and its working frequency directly determines the penetration depth of the ultrasonic signal and the detection resolution. In this test, the customer hoped to use the M33 ultrasonic testing platform to precisely calibrate the transducer frequency of their product, verifying whether the equipment performance matches the design specifications, providing a reliable basis for subsequent product optimization and field applications. After professional instrument testing, the frequency of this type of transducer is typically set around 2MHz, offering good signal penetration and stable echo reception capability in scenarios such as installation on the bottom of metal containers and oil level detection in tanks.
Going forward, Dayu Electronics will leverage its technical expertise in ultrasonic level (liquid level) detection to continuously support industry customers in achieving accurate, safe, and stable industrial measurements.
