The APG IRU-3430 Level Sensor is an ultrasonic level detector featuring both CSA Class 1, Div. 2 certification and increased power for better detection in difficult environments. The IRU-3430 series 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-3430 is the right sensor for your application.

The APG IRU-3430 includes a larger, more powerful transducer for level measurements from 1.25 to 50 feet for both liquids and solids. The basic accuracy is ±0.25% of detected range. The APG IRU-3630 features APG's AutoSense software for quick and easy programming in a variety of application settings making it hassle-free to set-up the system.

The IRU-3430 level sensors are designed for a variety of applications, and therefore have ample programming options to accommodate many needs. Output options include 4-20 mA or 4-20 mA with (2) NPN outputs.
