MB7092 XL-MaxSonar-WRMA1

High Performance Ultrasonic Precision Rangefinder

Product Description

The XL-MaxSonar-WRMA1 ignores smaller targets and only reports the range to target with the largest acoustic return. This is our most advanced weather resistant sensor designed for target detection and ranging outdoors or in tank or bin applications.

The weather resistant XL-MaxSonar-WRMA1 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.

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 XL‑MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long range detection zones.

MB7052 is the pulse width output version of this sensor.
MB7070 is the standard version of this sensor.

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.
