IRU-5320 Series Ultrasonic Sensors

The APG IRU-5320 series ultrasonic sensors use ultrasonic technology to provide a non-contact method of detecting level, presence/absence, volume, proximity and distance measurements. This versatility makes ultrasonics ideal for a variety of applications.

Ultrasonic sensors transmit pulsed waves of high frequency sound. If the sound wave meets a reflective object, such as liquid, it bounces back toward the sensor. The sensor records the time required for the sound wave to travel to the target and return. Using the speed of sound, which is a well-known variable, the sensor calculates the distance to the object.

Until recently, the many factors that influence the speed of sound created inaccurate readings. Now with low cost microprocessor technology, many of these variables can be factored into the equation and eliminated. Temperature change is one such variable. The IRU-5320 sensors use internal temperature compensation to offset the effects of these changes. The IRU-5320 can also compensate for other variables, such as wave action, agitators, and humidity. Sensor adjustments are made via a computer USB interface using an RST module* and Windows™ compatible software.
