Ultrasonic Sensor for Snow Depth - MB7334
HRXL-MaxSonar®-WRS3Ultrasonic snow depth sensors from MaxBotix Inc., feature high range stability during outdoor operation. We believe that our sensor's performance meet or exceed that of our competitors, yet feature a much lower cost.

Presented is our ultrasonic sensor's performance, from the MB7354, compared with the performance of the Judd Ultrasonic Snow Depth Sensor and Campbell Scientific SR-50 sensor.

MaxBotix Inc., has released another iteration of the HRXL‑MaxSonar‑WRS ultrasonic snow depth sensors. The new MB7334, MB7344, MB7354, and MB7374 are joining the MB7364 and MB7384 for snow depth measurement applications.

This article communicates the new features, filters, and accuracy in the newly released HRXL‑MaxSonar‑WRS product line. With this communication, performance graphs are shown with data from the MB7354 and our competitors for user comparison. We hope that that this shows that the HRXL‑MaxSonar‑WRS ultrasonic sensors performance meet or exceed that of our competitors, with a much lower cost.

The image below shows the distance, measured by the the MB7354, to the target, over five days. Presented are three million continuous readings, with rain, wind, and typical temperature swings of 15C per day.

Below is a comparison chart of the Judd Ultrasonic Snow Depth Sensor and the Campbell Scientific SR-50 sensor. This chart was created from data taken during a snow-free period in Milwaukee WI.
Judd Snow Sensor Accuracy, Campbell Snow Sensor Accuracy
This comparison chart was created by Wendy Ann Brazenec in 2005 as a thesis project to compare the accuracy of the snow depth measurement sensors manufactured by Judd and Campbell Scientific in 2005. For the full thesis please view this pdf.


The data speaks for itself. Even so, we believe that our ultrasonic sensor's performance is functionally equivalent to that of our competitors, yet feature a much lower cost.

We invite you to look at our new MB7334, MB7344, MB7354, and MB7374 (and our original MB7364 and MB7384 sensors). For more information regarding the HRXL-MaxSonar-WRS sensors, please see this web page.

Typical Wall Pipe Many customers have requested the option to mount an ultrasonic sensor in a pipe. During the testing and development cycle, we discovered a number of considerations and requirements that must be met for the application to be successful. When all of these are met, a user may be able to achieve the desired level of success for measuring the liquid level inside of a pipe.
