The APG MNU IS Modbus ultrasonic level sensor offers depth, level and volume measurement in hazardous locations requiring intrinsic safety ratings. The MNU IS carries cCSAus, ATEX and IECEx approvals and its optional lightning protection can also make it IEC 61000-4-5 compliant. APG's QuickMode gives this ultrasonic level sensor the ability to be ready to read in as little as 250 milliseconds for power-saving, on-demand measurements. With a measurement range from 1 to 25 feet, the MNU IS features a ±0.25% accuracy of the detected range and a 0.1 inch resolution.
The RS-485 Modbus RTU output makes the APG MNU IS Modbus ultrasonic level sensor fully programmable including setting a user-defined units of measure, response rate, volume calculations and more. The IP68 housing of this APG ultrasonic level sensor allows the unit to be submerged in up to 3 meters of liquid for up to 48 hours. Lastly, the standard temperature range for the MNU IS is -22° to 140°F (-30 to 60°C) but this can be upgraded to -4 to 122°F (-20 to 54°C) for more demanding applications.
