Product Description

The weather resistant SCXL-MaxSonar-WRS self‑cleaning sensor is a rugged ultrasonic sensor component module. This outdoor sensor provides very short to long distance detection and ranging in a compact, robust PVC housing. The ultrasonic sensor meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings.

The MB7584 SCXL-MaxSonar-WRST self‑cleaning sensor is a cost-effective, rugged ultrasonic sensor that is designed for reliable snow-depth measurement. The MB7584 features a self-cleaning transducer to remove condensation and ice buildup when operating in cold conditions. Internally, multiple sensor readings are analyzed using algorithms optimized for snow measurement. This is the base model for the SCXL‑MaxSonar‑WRST self‑cleaning snow-depth measurement sensors. The sensor accurately applies temperature compensation to every reading, using either the integrated temperature sensor or the optional external temperature sensor (HR-MaxTemp).

High output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms results in virtually noise free distance readings. This holds true even in the presence of many of the various acoustic or electrical noise sources. The SCXL‑MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

MB7564 is the RS232 version of this sensor.

Models with additional chemical resistance are available

The F-Option design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option when ordering.

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.
