MB7368 HRXL-MaxSonar-WRML

High Performance Ultrasonic Precision Rangefinder

Product Description

Features of the weather resistant MB7368, HRXL-MaxSonar-WRML, include millimeter resolution, short to long distance detection, range information from 300mm to 9999mm to the target with the largest acoustic return, a 6.7Hz read rate, and various output options: pulse-width, analog voltage, and RS232 serial.

The MB7369 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 which meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings (this product has multiple housing options available).

The HRXL-MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.
The MB7368 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 MB7368 will switch to the target that gives the next largest detectable return. This filtering makes the MB7368 one of our most advanced sensors for outdoor tank and bin applications.

In addition, the MB7368 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
MB7388 is the TTL version of this sensor.
MB7369 is the base level version of this sensor.

Models with additional chemical resistance are available

The F-Option (IP68) design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option (IP68) when ordering.
