Object Detection Ultrasonic Sensor


Designed For Detecting Solids And Moving Objects

The IRU-2000 ultrasonic sensor has a surface mount for flat surfaces and is ideal for absence/presence detecting, object profiling, and a variety of other applications.

Product Description

Built to mount on walls, ceilings, and other flat surfaces. The IRU-2000 transducers are often used for absence/presence detection, object profiling, and more.

Programming Options

The IRU-2000 ultrasonic sensors are designed for a variety of applications, and therefore have ample programming options to accommodate many needs.

Surface Mount

These ultrasonic sensors are built for use outside of the tank environment. Instead of a threaded fitting, they simply bolt onto a flat surface. The IRU-2000 transducers are often used for absence/presence detection, object profiling, and more.

Variety of Available Outputs

Outputs determine compatibility, so it’s nice to have options. From relays and trip points to 4-20mA and RS-485, the IRU-2000 ultrasonic sensors have you covered. Pick from our standard offerings or contact us about custom outputs.
