Our products are designed to be long-lasting, cost effective, and easy to use.All float level switches are individually built with strict attention to detail to meet the exact specifications of your process. Available as float level switches and displacer level switches, our product offering provides superior alarm and monitoring control for heavy industries such as power generation, refining, petrochemical and general manufacturing.Today’s high inventory costs plus the need for quick turnaround on plant maintenance projects or the routine replacement of thermocouples and RTDs dictates the need for standardization. Now you can standardize on one length sensor for all your temperature requirements. SOR® Type ATC, APO, and APH sensors are easily cut to length in the field to a minimum of 3 inches (7.62 cm) long. We produce our thermocouples with high quality construction in mind, using high pressure designs and a variety of metal options
