Mid Range Ultrasonic Level Sensor With Data Logging: 30 Feet

IRU-6429

DESCRIPTION
Features

Excitation for Data Logging

The IRU-6429 Ultrasonic Level Sensor offers accurate, real-time level measurement with built-in data logging capabilities. Featuring autosense software, this sensor enables quick and easy programming. Designed for tank monitoring and water/wastewater applications, it delivers a high-accuracy measurement of ±0.25% of the detected range.

This mid-range ultrasonic level sensor provides flexible output options, allowing users to select 0-2.5V or 0-5V during setup. With an operating range of 1 to 30 feet, it ensures precise level measurement in diverse environments. Built with a durable polycarbonate/PET housing, it withstands harsh conditions and features internal temperature compensation for reliable performance.
