Planar Ultrasonic Level/Ranging Sensor

Main Features:

This series comprises planar ultrasonic level and distance sensors specially designed for space-constrained applications. Featuring an ultra-thin stainless-steel flat probe and an M12 aviation‑grade connector, the devices integrate a high‑precision ultrasonic transmit/receive module and an RS485 signal‑processing circuit. By measuring the time of flight of the ultrasonic echo, they deliver non‑contact, highly accurate distance and level measurements. These sensors are widely suited for applications such as level monitoring in small storage tanks, internal positioning in automated equipment, and distance sensing in tight spaces, offering a compact and reliable non‑contact measurement solution for various industrial systems.

Core Features

Ultra-thin flat probe, ideal for tight spaces. It employs an ultra-thin stainless steel flat probe, which is lightweight and requires minimal installation space, allowing it to be embedded within equipment or mounted in tight spaces without compromising the overall structure—making it ideal for applications with constrained mounting environments.
Stainless steel probe and aviation connector, with a high degree of protection. The probe is made of stainless steel, offering corrosion resistance and wear protection. Paired with an IP67‑rated M12 aviation connector, it provides dustproof and waterproof performance, enabling reliable long-term operation in humid and dusty environments and enhancing overall equipment reliability.
RS485 digital signal output, compatible with industrial systems. : Built-in RS485 signal processing circuit, supporting the Modbus protocol, enabling direct connection to PLCs and industrial controllers for remote data transmission and centralized monitoring, and compatible with industrial automation systems.
Strong anti-interference capability and stable measurement. : Built-in digital filtering algorithms effectively suppress electromagnetic interference and environmental noise, ensuring stable echo signals, excellent measurement repeatability, and high accuracy, thereby meeting the demands of industrial‑grade applications.

Typical application scenarios

Level monitoring and control for small storage tanks, reactors, and process vessels
