This ultrasonic tank level sensor features a 1mm resolution with a 5-meter maximum range. The sensor has the following outputs: RS232 & TTL Serial, analog voltage, and analog envelope.
Features of the weather-resistant MB7851, Tank Sensor, includes millimeter resolution, short to long-distance detection, range information from 50 mm to 5000 mm for liquid level detection, a ~2Hz read rate, and three simultaneously available outputs: a real-time analog voltage envelope, a scaled analog voltage, and serial communication in either RS232 or TTL format.
The MB7851 Tank Sensor is a low‑cost liquid-level monitoring sensor that uses ultrasonic technology for non-contact sensing. The MB7851 is designed to be an easy-to-use sensor for applications where liquid-level detection is desired. This sensor is great for use in containers that are typically difficult for ultrasonic devices such as tanks, barrels, and bins. This is because the MB7851 has a teach feature (only available if using serial communication), that can train the sensor to what an empty container looks like. This helps allow the sensor to range properly even in the presence of otherwise detectable obstructions like corrugation.
The MB7851 is factory calibrated to match sensor beam patterns and provide reliable long-range detection zones.
In addition, the MB7851 offers virtually noise-free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.
