Product information "MaxBotix MB7789 4-20SC-MaxSonar-WRMI"

Features of the weather resistant MB7789, 4-20SC-MaxSonar-WRMI, include reduced impact of condensation and frost when ran continuously in closed or high-moisture environments, millimeter resolution, short to long distance detection, range information from 500mm to 5000mm to the target with the largest acoustic return, a 0.6Hz read rate, and the industry standard 20-4mA output where 20mA is minimum range and 4mA is maximum range.

The MB7789 from the 4-20SC-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 4-20SC-MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

The MB7789 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 MB7789 will switch to the target that gives the next largest detectable return. This filtering makes the MB7789 one of our most advanced sensors for outdoor tank and bin applications.

In addition, the MB7789 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.

Intended for applications requiring the resistance of condensation in high moisture environments, our self-cleaning function is designed to run continuously in order for the self-cleaning feature to be active.
