MB7369 HRXL-MaxSonar-WRM

High Performance Ultrasonic Precision Rangefinder

Product Description

The HRXL-MaxSonar-WRM ignores smaller targets and only reports the range to target with the largest acoustic return. This is our most advanced weather resistant sensor designed for target detection and ranging outdoors or in tank or bin applications.

The HRXL-MaxSonar-WRM sensors are equipped with filtering firmware which allows the sensor to ignore smaller targets and noise, and still report the target that gives the largest acoustic return. (The sensor will also reject periodic noise, even noise that has a higher amplitude than the acoustic return from the target.) This gives users the flexibility to consistently range larger targets in the presence of clutter and noise. If the largest target is removed from the field of view, the HRXL-MaxSonar-WRM will switch to the target that gives the next largest detectable return.

The Most-Likely filter is designed to report the distance to the largest acoustic return while ignoring smaller targets. When targets are of similar amplitude reflections, preference is given to the closest target.

MB7360 is the standard RS232 version of this sensor line.

Models with additional chemical resistance are available

The F-Option (IP-68) design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option (IP-68) when ordering.
