Ultrasonic level transmitter uses loop power
The ABB LST300 ultrasonic level transmitter is an intelligent, compact level instrument applicable to a wide range of industries and applications. It offers the benefits of a remote device in a compact instrument and delivers enhanced reliability and performance, reducing the cost of ownership. The LST300 allows users to perform measurements and add features that required 4-wire power in the past. It measures up to 10 m range while powering a graphic HMI, and functions using only loop power without any special requirements. It constantly monitors measurement data, optimizing the system for the best signal at any tank size.
