Description

The MB7480-101 HR-MaxSonar-WRI sensor utilizes advanced ultrasonic time-of-flight (ToF) technology to deliver precise, non-contact distance measurements. Its 4-20mA analog output provides a robust, noise-resistant signal ideal for long-distance transmission in industrial automation and process control systems, where voltage drop or EMI can be a concern.

Engineered for durability, the sensor features an IP67 enclosure, protecting its internal electronics from dust ingress and temporary immersion in water. This makes it suitable for outdoor applications, tank level monitoring, and other challenging environments. The sensor’s internal filtering algorithms ensure reliable and stable range readings even in the presence of acoustic noise or electrical interference.

Key Features

  • Industrial 4-20mA current loop output for robust, noise-immune signal transmission.
  • IP67-rated weatherproof and dust-tight housing for harsh environment deployment.
  • Wide supply voltage range (10-32V DC) for flexible system integration.
  • High-resolution ultrasonic ranging with excellent repeatability.
  • Compact, threaded barrel design for easy mounting and installation.
  • High Mean Time Between Failures (MTBF) exceeding 200,000 hours for reliable long-term operation.
  • Internal temperature compensation for stable performance across the full operating range.

Applications

  • Industrial tank and silo level measurement for liquids and solids.
  • Process control and automation for distance-based triggering.
  • Bin level monitoring in agricultural and material handling systems.
  • Obstacle detection and positioning in rugged mobile equipment.
  • Water level monitoring in weather stations and environmental systems.

Frequently Asked Questions

What is the output signal of the MB7480 sensor and how do I interface with it?

The MB7480 outputs a standard industrial 4-20mA current loop signal. To read it, you need a precision resistor (typically 250 ohms) to convert the current to a voltage (1-5V) that can be measured by a PLC analog input module, data acquisition system, or microcontroller with an ADC. Ensure your control system is configured for a 4-20mA input.

What power supply is required for the MB7480 sensor?

The sensor requires a DC power supply between 10V and 32V. The supply must be capable of sourcing sufficient current for the loop; at 20mA output, the sensor's internal circuitry will drop the remaining voltage. A common 24V DC industrial supply is perfectly suitable and recommended for most applications.

How do I mount and calibrate the MB7480 for accurate level measurement?

Mount the sensor vertically above the target surface, ensuring a clear acoustic path free of obstructions. The sensor is factory-calibrated. For level measurement, you map the 4-20mA output linearly to the 50 cm to 5 meter range (e.g., 4mA = 5m, 20mA = 0.5m). No user calibration is typically required, but you should verify readings against a known reference in your specific installation.
