MB7574 SCXL-MaxSonar-WRST7

High Performance Ultrasonic Precision Rangefinder

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 MB7574 SCXL-MaxSonar-WRST7 self‑cleaning sensor is a cost-effective, rugged ultrasonic sensor that is designed for reliable snow-depth measurement. The MB7574 features a self-cleaning transducer to remove condensation and ice buildup when operating in cold conditions. The MB7374 self‑cleaning sensor is the recommended sensor for snow-depth measurement for users requiring TTL serial data. The MB7574 self‑cleaning sensor has an internal filter that is a recent biased exponential weighted average. This filter is limited to change a maximum of 1 mm per reading. 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.

MB7554 is the RS232 version of this sensor.

Models with additional chemical resistance are available

The F-Option (IP-68) design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option (IP-68) when ordering.
