Ultrasonic Sensors

We offer a wide range of ultrasonic sensors using ultrasonictechnology used for Air bubble, point level, continuous level monitoring. Our ultrasonic sensors measure liquid level despite variations in transparency, viscosity, color or dielectric. These solutions include air bubble detection for medical pumps; point and continuous level sensors for the semiconductor and high purity markets; and point level sensors for a variety of process control applications. We off er high accuracy, high frequency, short range continuous measurement sensors through air for process control.

We also offer standard products that provide a system without moving parts, adjustments, or maintenance. By working closely with OEMs to off er custom sensors suited for temperature ranges of -30°C to 150°C, pressures to 1,000 psi, various input/output confi gurations and multiple sensing points.
