Note 1 All of the MaxSonar range finders will detect an object from the minimum reported distance to the front face of the sensor. The sensors will typically report the distance to objects closer than the minimum reported range as the minimum reported range.

Note 2 There are 2 different stability filter variations. The 'Stability Filter' reads the range to the target and verifies the range to the target. The MB70XX series sensors have a 3 read stability filter that compares recent range readings to determine if the target is valid. This filter is best for applications with slow moving targets such as tanks or water levels. The 'Best Target' filter ranges to the largest amplitude reflection and ignores the small target reflections.

Note 3 The MB7300 series sensors have an advanced internal noise filter that provides reading to reading stability. This filter is able to handle the presence of random noise and other ultrasonic sensors with little, to no interference. These sensors are designed to operate in free‑run mode for best stability and accuracy.

Note 4 The MB7334, MB7344, MB7354, and MB7374 have a heavily filtered output that designed to provide more accurate information in real-world environments. This filter improves sensor accuracy and stability by reducing the influence of wind, acoustic noise, thermal pockets, and other effects on the sensor output. These sensors are designed for snow, grain level measurement, or any high accuracy requirement. For a complete description please reference the HRXL-MaxSonar-WRS Datasheet.

UCXL-MaxSonar-WR
The condensation issue in tanks and other moisture-prone environments is solved!
The SCXL‑MaxSonar sensor series, based on our popular HRXL-MaxSonar-WR product line, features a self-cleaning protocol gently heats the face of the transducer, atomizing any condensation to prevent moisture buildup.
