Description

The MB7369 from MaxBotix’s HRXL-MaxSonar-WR series is engineered for robust, long-distance ranging in challenging conditions. Its 42kHz ultrasonic transducer, combined with real-time waveform analysis and variable gain control, delivers stable, noise-resistant distance readings even in the presence of acoustic interference. The sensor is factory-calibrated for a narrow beam pattern, enhancing target discrimination.

This module employs sophisticated signal processing to report the distance to the largest acoustic return, effectively ignoring smaller targets and clutter. If the primary target is removed, it seamlessly switches to the next largest detectable object. This makes it exceptionally reliable for continuous monitoring applications where consistent detection of a primary object is critical, such as in bulk material level sensing.

Key Features

  • Advanced Ranging Logic: Selectively reports distance to the largest target return, providing stability in environments with multiple reflectors or obstructions.
  • Multi-Interface Output: Simultaneously provides RS232 serial data, analog voltage (scaleable with distance), and a pulse-width output for maximum compatibility with various controllers and data acquisition systems.
  • Environmental Durability: Housed in a sealed PVC enclosure rated IP67 for protection against dust and temporary water immersion, suited for outdoor and industrial installations.
  • High Precision: Delivers 1mm resolution distance measurements, enabling precise monitoring and control applications.
  • Low Power Design: Operates from a wide 2.7V to 5.5V supply with an average current consumption of only 2.9mA, ideal for battery-powered or energy-conscious systems.
  • Integrated Signal Conditioning: Features real-time automatic calibration and noise rejection algorithms to ensure reliable data in electrically or acoustically noisy settings.

Applications

  • Outdoor tank and bin level measurement for liquids and bulk solids in agriculture, water treatment, and industrial storage.
  • Obstacle detection and ranging for autonomous mobile robots (AMRs) and guided vehicles in warehouse and outdoor settings.
  • Distance monitoring in harsh environmental conditions, such as construction site equipment positioning or marine vessel docking aids.
  • Process control and inventory management systems requiring reliable, non-contact level sensing of primary materials behind grating or partial obstructions.

Frequently Asked Questions

What are the available output interfaces on the MB7369 sensor?

The MB7369 provides three simultaneous output options: RS232 serial data (TTL-level), an analog voltage that scales linearly with distance, and a pulse-width (PWM) output where the pulse length corresponds to the measured range. This allows direct integration with microcontrollers via serial, ADC pins, or pulse-in functions, as well as with PLCs using analog or serial inputs.

How does the 'largest target' detection feature work?

The sensor's firmware analyzes the acoustic return waveform and selects the largest amplitude reflection as the primary target. This filters out smaller objects, clutter, or false echoes. If the largest target moves out of view, the sensor automatically switches to reporting the distance of the next largest detectable target, providing stable readings in complex environments like bins with internal structures.

Is the MB7369 suitable for outdoor use, and what is its IP rating?

Yes, it is specifically designed for outdoor and industrial environments. It features an IP67-rated PVC housing, meaning it is dust-tight and can withstand temporary immersion in water up to 1 meter for 30 minutes. Its housing is also threaded to match standard 3/4-inch PVC pipe fittings for easy mounting.

What is the power requirement and current consumption?

The sensor operates from a wide voltage range of 2.7V to 5.5V DC, making it compatible with both 3.3V and 5V logic systems. Its average current draw is very low at 2.9mA, which is ideal for battery-powered, solar-powered, or other low-energy applications where continuous monitoring is required.
