Introduction

The weather resistant 4-20SC‑MaxSonar‑WR is a rugged, ultrasonic sensor component module that features the industry standard 4-20mA analog current interface. This outdoor sensor provides very short- to long- distance detection and ranging in a compact, robust PVC housing. This ultrasonic sensor meets the IP67 water intrusion standard and is available in multiple packaging types. 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 4‑20SC‑MaxSonar‑WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones. The 4-20SC-MaxSonar-WRM sensors are equipped with filtering firmware which allows the sensor to ignore smaller targets and noise, and still report the target that gives the largest acoustic return. (The sensor will also reject periodic noise, even noise that has a higher amplitude than the acoustic return from the target.) This gives users the flexibility to consistently range larger targets in the presence of clutter and noise. If the largest target is removed from the field of view, the 4‑20SC‑MaxSonar‑WRM will switch to the target that gives the next largest detectable return. The Most‑Likely filter is designed to report the distance to the largest acoustic return while ignoring smaller targets. When targets are of similar amplitude reflections, preference is given to the closest target. The MB7769 features an effective self-cleaning capability designed to reduce the impact of condensation in closed or high-moisture (dew, frost, etc.) environments. This sensor is a cost-effective solution for applications where precision range-finding, low-voltage operation, space saving, low-cost, self-cleaning, and weather resistance (IP67) rating is needed.
