SOR Inc.

SOR® manufactures a full line of pressure, differential pressure, temperature, vacuum and level switches that are certified fit for use in SIL (Safety Integrity Level) environments. We are one of only a few manufacturers to offer its entire range of switches certified to the IEC 61508 standard. Our fundamentals include superior quality, excellent service and quick delivery.

SOR® pressure switches have earned a long-time reputation for their high quality, rugged construction and reliable performance under the most demanding applications. We offer explosion proof, hermetically sealed, and weatherproof switches. We design our pressure switches with high performance in mind, crafting custom, durable pressure switches with the approval of multiple agencies. 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.
