MB7389 HRXL-MaxSonar-WRMT Outdoor Ultrasonic Sensors from MaxBotix

Maxbotix manufacture many sensors which can withstand harsh outdoor conditions. When dust, moisture, or harsh handling of the ultrasonic sensor is unavoidable, then this Maxbotix MB7389 HRXL-MaxSonar-WRMT Outdoor Ultrasonic Sensor is ideal for your application.

Features of the weather resistant MB7389, HRXL-MaxSonar-WRMT, include millimeter resolution, short to long distance detection, range information from 300mm to 5000mm to the target with the largest acoustic return, a 6.7Hz read rate, and various output options: pulse-width, analog voltage, and TTL serial.

The MB7389 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 MB7389 is reports the distance to the largest acoustic return while ignoring smaller targets. When targets are of similar amplitude reflections, it gives preference to close targets. 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 MB7389 will switch to the target that gives the next largest detectable return. This filtering makes the MB7389 one of our most advanced sensors for the outdoor tank and bin applications.

In addition, the MB7389 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.

Note: This module doesn’t come with F-option(equips chemically inert material’s covering to the sensor) or P-option(applies Parylene coating on the Aluminum transducer) protection. To buy MB7389 HRXL-MaxSonar-WRMT Outdoor ultrasonic sensor with F-option or P-option please contact us at Robu.in support channel.
