SST’s Alternative to Float Switch Technology

Float Switch Technology Alternative

Optical liquid level switches are a premium solution to level control but at a price which is comparable with other less reliable low cost solutions. We offer a full range from basic products with control outputs to high temperature, increased voltage and current outputs which allow customers to switch relays and equipment directly from the sensor and are a good alternative to float switch technology.
