MB7388 HRXL-MaxSonar-WRMLT

Features of the weather-resistant MB7388, HRXL-MaxSonar-WRMLT, include millimeter resolution, short to long-distance detection, range information from 500mm to 9999mm for the largest target, a 6Hz read rate, and various output options: pulse-width, analog voltage, and TTL serial.

The MB7388 from the HRXL-MaxSonar-WR line of outdoor sensors is a rugged ultrasonic sensor component module. This sensor comes in a compact and robust PVC housing that meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings.

The HRXL-MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

The MB7388 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. This gives users the flexibility to consistently detect larger targets in the presence of clutter and noise.

If the largest target is removed from the field of view, the MB7388 will switch to the target that gives the next largest detectable return. This filtering makes the MB7388 one of our most advanced sensors for outdoor tank and bin applications.

In addition, the MB7388 offers virtually noise-free distance readings through the use of high-output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.

Variations on this sensor model
