Ultrasonic level sensor ULS Series

Image ULS

The ULS Series level transmitter is a ultrasonic sensor designed to measure distances up to 9 meters.

The working principle of the ultrasonic sensors is based on a sound emission from the sensor and its reflection by an obstacle. Depending on the speed of propagation and time elapsed since the emission, the distance between the sending and the receiving is calculated proportionally. It can be used in liquids and in solids evironments. It also can be used even in very thin structures.

Available with 0-10VDC, 0-5V, 0.5-5V, 0-20mA, 4-20mA, RS485, RS232, CANOpen and switch output options.
