Description

RS485 750cm Ultrasonic Level Sensor uses ultrasonic sensing technology for distance measurement. Equipped with bell-mouth, the detection range can be up to 750 cm, and the resolution can reach 1mm. With an IP67 waterproof ultrasonic transducer, it has strong adaptability to the working environment.

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
