Datasheet
The IRU-2420 provides a non-contact method of detecting level, presence/absence detection, volume, proximity and distance. With built in technology to compensate for unpredictable variables such as humidity, temperature and agitators, the IRU is the right sensor for your application.
Hazardous Location Certified
IRU-2420 ultrasonic sensors are suitable for hazardous locations classified under CSA Class 1, Div. 2.
Flexible Programming
This series of ultrasonics was designed with flexibility in mind. It features our AutoSense software for quick and easy programming in a variety of application settings.
A Good Fit
With a 25 ft. range, a 2 in. NPT fitting, and a 4-20mA output, the IRU-2420 sensors work well for many tank level applications.
