The Leveltrak can be used as a replacement for mechanical float switches. It detects level without any moving parts. Using patented capacitive sensing technology, the sensor determines level by measuring the point of dielectric contrast that occurs at the level height. Priced from $295 to $395, the Leveltrak features an enhanced software algorithm that scans 16 sensing fields along the length of its probe to determine the point at which the change in dielectric occurs. Upon startup, the sensing fields are evaluated every 8 msec to provide continuous level indication. Fluid level is indicated on a three-digit numeric LED display that can be programmed to read level in inches or centimeters. Output functions and fluid type can be set via two simple pushbuttons without removing the sensor from the process. Leveltrak models are available with two or four switching outputs, as well as an analog and switching output model. One Leveltrak can replace up to four binary switches. All models feature independent overflow protection that operated an additional output, independent of the sensor's scanning function to ensure protection from spillage.
