Ultrasonic Range Finder - HRXL-MaxSonar-WRST7(MB7374)
Description:
The weather resistant MB7374 HRXL-MaxSonar-WRST7 has millimeter resolution and a 6Hz read rate, and provides short to long distance detection and range information from 500mm to 5000mm for the nearest detectable target. It comes with heightened sensitivity over our standard sensors, and includes various output options: pulse-width, analog voltage, and TTL serial.
耐候性 MB7374 HRXL-MaxSonar-WRST7 具有毫米分辨率和 6Hz 讀取率，並為最近的可探測目標提供從 500 毫米到 5000 毫米的短距離到長距離檢測和距離信息。它比我們的標準傳感器具有更高的靈敏度，並包括各種輸出選項：脈衝寬度、模擬電壓和 TTL 串行。
The MB7374 from the HRXL-MaxSonar-WRS line of outdoor sensors is a rugged ultrasonic sensor component module. This sensor comes in a compact and robust PVC housing which meets the IP67 water intrusion standard and matches standard electrical 3/4 inch PVC pipe fittings.
HRXL-MaxSonar-WRS 系列室外傳感器中的 MB7374 是一款堅固耐用的超聲波傳感器組件模塊。該傳感器採用緊湊而堅固的 PVC 外殼，符合 IP67 防水標準並與標準的 3/4 英寸 PVC 電氣管件匹配。
The HRXL-MaxSonar-WRS sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.
HRXL-MaxSonar-WRS 傳感器經過工廠校準，以匹配窄傳感器光束模式並提供可靠的遠程檢測區域。
The MB7374 has an internal filter that is a recent biased exponential weighted average. This filter is limited to change a maximum of 7mm per second. The sensor accurately applies temperature compensation to every reading, using either the integrated temperature sensor or the optional external temperature sensor, HR-MaxTemp.
MB7374 有一個內部濾波器，它是最近的偏置指數加權平均值。此過濾器每秒最多可更改 7 毫米。該傳感器使用集成溫度傳感器或可選的外部溫度傳感器 HR-MaxTemp，準確地對每個讀數應用溫度補償。
In addition, the MB7374 offers virtually noise free distance readings through the use of high-output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.
此外，MB7374 通過使用高輸出聲功率與連續可變增益、實時背景自動校準、實時波形特徵分析和噪聲抑制算法相結合，提供幾乎無噪聲的距離讀數。即使存在許多不同的聲學或電噪聲源，這也是正確的。
