What is the blanking distance, and why is it important?

The IRU-5000 has a 4-inch blanking distance, which is the minimum distance from the sensor face where measurements cannot be taken. This ultra-short blanking distance allows for more accurate level measurement in compact spaces.

This sensor provides multiple output options, including:

  • 4-20mA isolated output
  • 4-20mA with NPN trip points
  • Programmable voltage output (0-2.5V or 0-5V selectable)

Autosense software enables quick, hassle-free programming by automatically adjusting the sensor’s parameters based on its environment, reducing installation time and ensuring accurate readings.

The sensor offers flexible mounting options with both 1-inch NPT and 2-inch NPT threads, making it compatible with various tank and tote installations.

Yes, the IRU-5000 is compatible with the RST-5003 for internet connectivity and remote monitoring applications.
