Description
The ULS-301-S ultrasonic level transmitter provides a continuous level indication in applications up to 14 feet. The rugged housing is made of all 316 stainless steel and is rated Nema 4x. It has 4-20Ma and 0-10v outputs for convenient hook up to digital displays and PLC’s. The sensor is push-button “teachable” so it can be calibrated in the field without the need for a computer or software. It requires 24vdc power and comes standard with 6ft of cable.
Operating Principle
The sensor sends out a sound wave toward the media in a pulsed fashion. The sound wave hits the media and reflects that sound back to the sensor. The sensor calculates the time it took for the sound to travel to determine the distance from the sensor to the media.
