IRU-9400 Self Contained Ultrasonic Level Sensor
Flexible by Design
The IRU-9400 series provides a versatile range from 6 inches to 35 feet along with a more sensative
transducer to detect difcult targets. This sensor is great for non-reective and/or soft surfaces.
With built in technology to compensate for temperature the IRU-9400 is well suited for object
detection and is recommended for indoor use.
Features
• Easily congured for obstacle detection applications
• Internal Temperature Compensation
• Works on solids and liquids
