Weather Resistant (IP67) Sensors, and Optional Chemical Resistance

The industrial outdoor HRXL-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 HRXL‑MaxSonar‑WR outdoor ultrasonic sensors have high power output, noise rejection, auto calibration, and factory calibrated beam patterns. Users should select a sensor with their outputs of choice and reading filtering that matches their application. Models are available with analog voltage output, pulse width output, & serial digital output (RS232 or TTL).

In addition to the standard HRXL-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 HRXL-MaxSonar-WR sensor are: Aluminum (oxidized surface), PVC, & silicone rubber (VMQ).

F-Option

The exposed materials of a properly mounted HRXL-MaxSonar-WR sensor with the F-Option added are: Aluminum (oxidized surface), PVC, & Flourosilicone (with an additional back up FEP Teflon® seal).

Additional Considerations

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 (3/4" National Pipe Thread Straight)  MB7950 Mounting hardware can be purchased along with your sensor.

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.

Rugged & Reliable Outdoor Ultrasonic Sensors

The industrial HRXL‑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 HRXL-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.

Internal Temperature Compensation

The speed of sound in air increases about 0.6 meters per second, per degree centigrade. Because of this, each HRXL‑MaxSonar‑WR is equipped with an internal temperature sensor which allows the sensor to apply a compensation for speed of sound changes.

With the internal temperature sensor, range readings immediately (within twenty seconds) after power up are the most accurate, and this is ideal for battery applications where the sensor is powered off most of the time. The self heating (15mW at 5V, or 8mW at 3.3V) will change the temperature of the sensor by 3 degrees C or so. (The amount of self heating is also slightly dependent upon user mounting). As such, self heating will cause the sensor to read the actual air temperature inaccurately.

External Temperature Sensor

With the HR‑MaxTemp connected to the HRXL‑MaxSonar‑WR line of sensors, realtime automatic temperature compensation is available. The HR-MaxTemp allows the HRXL‑MaxSonar‑WR sensor to monitor the changes to air temperature while ignoring self-heating.

The HRXL‑MaxSonar‑WR is designed to used alongside the HR‑MaxTemp temperature sensor. On power-up the HRXL‑MaxSonar‑WR will automatically detect an attached temperature sensor and begin to apply temperature compensation for the speed of sound changes to all range outputs.

The Interface

The HRXL‑MaxSonar‑WR interface was designed to be very easy and intuitive to use. The interface output formats included are pulse width output, analog voltage output, and RS232 or TTL serial output. All interfaces work without user code or complicated setup strings.

The Power Requirements

The HRXL‑MaxSonar‑WR functions throughout a 2.7V 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 HRXL‑MaxSonar‑WR sensors have a 3.1mA 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 HRXL‑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.

The Calibration

Each HRXL‑MaxSonar‑WR is made and tested for proper operation at our facility in the USA and comes with a factory calibrated narrow beam pattern to help ensure consistent operation of the sensor even from part to part.

The HRXL‑MaxSonar‑WR automatically calibrates to its environment before every range reading. This calibration includes compensation for temperature, voltage, humidity, acoustic noise, and electrical noise conditions.

The Price

This sensor is designed to be sold in volume. As a result, our customers benefit from our large production volumes and distributed engineering expenses.

Typical Wall Pipe Many customers have requested the option to mount an ultrasonic sensor in a pipe. During the testing and development cycle, we discovered a number of considerations and requirements that must be met for the application to be successful. When all of these are met, a user may be able to achieve the desired level of success for measuring the liquid level inside of a pipe.
