Features of the weather resistant MB7489, 4-20HR-MaxSonar-WRMI, include millimeter resolution, short to long distance detection, range information from 500mm to 5000mm to the target with the largest acoustic return, a 7.5Hz read rate, and the industry standard 20-4mA output where 20mA is minimum range and 4mA is maximum range.
The MB7489 from the 4-20HR-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 4-20HR-MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.
The MB7489 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 MB7489 will switch to the target that gives the next largest detectable return. This filtering makes the MB7489 one of our most advanced sensors for outdoor tank and bin applications.
In addition, the MB7489 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.

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.
The MaxBotix F-Option (IP68) provides additional protection necessary in a few hazardous chemical environments. Extremely corrosive gases or liquids can degrade or compromise the operation of the sensing unit. As a result, we offer a more chemically inert seal which allows our sensors to operate in all but the harshest of chemical environments. In addition to the chemical resistance, the sensor has improved performance in wet or dust environments.
Please Note: Our sensors are designed for operation in normal atmosphere (air). Please be aware that the speed of sound and atmospheric attenuation may change as a result of the transmission properties of different chemical/air mediums. Users are strongly encouraged to characterize and test the operation of the sensor in the new medium to verify operation, and properly scale the outputted range information.
