KSonic Micro

The KSonic Micro is a compact, low-cost, ultrasonic level transmitter/ switch that is designed for liquid and bulk solids level applications. Ultrasonic measurements are based on the time of flight (TOF) of an acoustic wave that is emitted from a transducer and directed toward the product being measured. This wave is reflected back toward the transducer and then converted to an electric signal. Its variable GAP (gain, amplitude and power) technology provides a very narrow beam angle of less than 4 deg., which allows the transmitter to take accurate measurements in narrow vessels, and function in the presence of dust, vapor or foam. It measures liquid levels to 32.8 ft (10 m) and bulk solids to 16 ft (5 m). Its 4–20-mA output is standard for remote indication or remote control, and it has a single-pole/double-throw (SPDT) relay that can be used to activate alarms and pumps. The unit is housed in an IP65 polycarbonate enclosure and the transducer has polyvinylidene fluoride (PVDF) wetted parts for corrosive environments.
