Weather Resistant (IP67) Sensors, and Optional Chemical Resistance
The industrial outdoor I2CXL-MaxSonar-WR sensors have a robust PVC housing designed to meet IP67 water intrusion. The sensors provide short to long distance detection and ranging with a narrow beam pattern. The I2CXL‑MaxSonar‑WR outdoor ultrasonic sensors have high power output, noise rejection, auto calibration, and factory calibrated beam patterns
In addition to the standard I2CXL‑MaxSonar‑WR, MaxBotix Inc., has developed the F‑Option for additional protection necessary in a few hazardous chemical environments. Extremely corrosive gases or liquids can degrade or compromise the operation of the sensing unit. As a result, we offer a more chemically inert seal which allows our sensors to operate in all but the harshest of chemical environments. In addition to the chemical resistance the sensor has improved performance in wet or dust environments.
Standard Weather Resistant Models
The exposed materials of a properly mounted I2CXL-MaxSonar-WR sensor are: Aluminum (oxidized surface), PVC, & silicone rubber (VMQ).
The exposed materials of a properly mounted XL-MaxSonar-WR sensor with the F-Option added are: Aluminum (oxidized surface), PVC, & Flourosilicone (with an additional back up FEP Teflon® seal).
To ensure long term operation of the sensor, terminal connections should not be exposed to water, dust, or other chemicals. Follow proper mounting when installing your sensor. This is easily accomplished using standard PVC pipe fittings which match the provided mounting threads. MB7950 Mounting hardware can be purchased along with your sensor for the 3/4 NPS threading.
Sensors are designed for operation in air, but may work well in many gases. Testing for proper operation is encouraged. Compensation for speed of sound changes in other gases should be applied to sensor output, this is often accomplished through a simple 2‑point linear calibration.
The industrial XL‑MaxSonar‑WR products are the highest quality for cost outdoor ultrasonic sensors on the market. They provide an industrial component module solution that offers easy to use outputs, weather & dust resistance, no sensor dead zone, calibrated narrow beam patterns, stable range readings, low power demands, and a host of other features detailed in the product datasheets.
The I2CXL-MaxSonar-WR sensors represent an industry revolution that has already found use in a number of advanced or industrial solutions where ultrasonic sensors have not been historically considered a viable solution due to unstable readings, high cost, and high power requirements.
The Noise Filtering
The sensor dynamically adjusts its sensitivity to compensate for outside electrical & acoustic noise sources.
The I2CXL‑MaxSonar‑WR interface was designed to be very easy and intuitive to use. Communication is provided over the I2C bus, featuring a very simple command set.
The Power Requirements
The I2CXL‑MaxSonar‑WR functions throughout a 3.0V to 5.5V operational voltage range. This allows for easy integration at either 3.3V or 5V and means that users of low voltage microcontrollers, or those who wish to operate in solar or battery based systems do not have to provide an extra power supply for the sensor.
The I2CXL‑MaxSonar‑WR sensors have a 4.4mA average current draw during free ranging operation.
The Controlled Narrow Beam Shape
Similar ultrasonic products may have frequent side lobe detection and can even falsely trigger on objects behind or to the sides of the sensor. The I2CXL‑MaxSonar‑WR offers a controlled narrow beam that is designed to reject small objects (clutter) outside of the central beam area and provides long-range sensitivity without detecting frivolous or unwanted targets
Each I2CXL‑MaxSonar‑WR is tested for proper operation at our facility and comes with a factory calibrated narrow beam pattern to help ensure consistent operation of the sensor even from part to part.
The I2CXL‑MaxSonar‑WR automatically calibrates to its environment before every range reading. This calibration includes compensation for voltage, humidity, acoustic noise, and electrical noise conditions. Temperature compensation for speed of sound changes are not applied.
This sensor is designed to be sold in volume. As a result, our customers benefit from our large production volumes and distributed engineering expenses.
