750cm Ultrasonic Level Sensor (RS485)

The RS485 750cm Ultrasonic Level Sensor offers 1mm resolution, IP67 protection, and a bell-mouth design for long-range accuracy. With RS485 and LoRaWAN® support, it’s ideal for industrial and environmental monitoring.

---

The RS485 750cm Ultrasonic Level Sensor uses ultrasonic technology for accurate distance measurement. Equipped with a bell mouth, it offers a detection range of up to 750cm with a 1mm resolution. Its IP67-rated waterproof transducer ensures reliable performance even in harsh environments.

This high-precision, low-power sensor is designed for large-scale distance monitoring, providing stable and accurate readings across a wide range. It’s ideal for use in industrial or outdoor applications where durability and accuracy are essential.

Supporting the RS485 serial communication protocol, the sensor can be easily integrated with other devices. It’s also compatible with the SenseCAP LoRaWAN® Data Logger, enabling connection to a LoRaWAN® network for low-power, long-range data transmission.

Features

• Measuring ranges: With an intelligent signal processing circuit, and equipped with a bell-mouth, the measurement distance can be up to 750cm, and the blind zone is less than 28cm.
• High precision: Built-in high-precision ranging algorithm, measurement accuracy ±(1+S*0.3%)
• Strong robustness: IP67 protection, suitable for wet, harsh environments
• Low power consumption: Average current ＜10 mA
• Built-in on-board temperature compensation: Automatic correction of temperature deviation
