Our industrial ultrasonic sensors and ultrasonic distance sensors achieve non-contact distance and displacement detection by measuring the time of flight of ultrasonic echoes. They are insensitive to the color, material, surface reflectivity, and transparency of the target object. These sensors are particularly suitable for tank level monitoring (including liquid surfaces, slurries, powders, and granular materials), warehouse and stacking height management, access control and barrier position control, as well as obstacle avoidance, deceleration, and docking for AGVs/AMRs, functioning perfectly as an ultrasonic sensor for robot applications.

This subcategory includes various models for liquid level measurement, acting as a reliable ultrasonic level sensor or ultrasonic water level sensor. They offer a versatile ultrasonic sensor range of approximately 0.5–6 m (multiple specifications available). The sensors feature a small blind zone, millimeter-level resolution (ideal when you need a high resolution ultrasonic sensor), and good repeatability. Both narrow and wide sound beams are available to accommodate long range distance sensor needs and short-distance obstacle avoidance, enabling reliable obstacle detection using ultrasonic sensing.

ISSR high accuracy ultrasonic sensor models incorporate built-in temperature compensation and adaptive gain/filtering, and support window detection, background suppression, and crosstalk immunity. Stable distance measuring sensor output is maintained even when multiple units operate simultaneously at close range. A variety of interfaces are available, including 4–20 mA / 0–10 V analog outputs (functioning as an ultrasonic level transmitter), PNP/NPN switching outputs, and digital outputs (such as TTL232), as well as a detection range learning function.

Featuring a compact housing with high protection and contamination resistance (e.g., optional IP67/IP68), they serve excellently as a waterproof ultrasonic sensor or water resistant ultrasonic sensor. Certain models are also available with chemically resistant surfaces, making them suitable for outdoor and corrosive environments, and can even be adapted as an underwater ultrasonic sensor in specific enclosures.

Overall, this product series offers broad ultrasonic sensor applications, helping users quickly build stable and traceable non-contact distance sensor and level measurement solutions under a wide range of operating conditions.
