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.

Air Pressure Switches

Air Pressure Switches

A mechanical device called an air pressure switch uses pressure to regulate how an electric air compressor operates. The device's air pressure circuit mechanism supplies the motor with electricity. A pressure switch relief valve is a...

Differential Pressure Switch

Differential Pressure Switch

Differential pressure is the difference in pressure between two points that is measured using different types of pressure sensing devices. An essential part of differential pressure measurement are gauges and switches that are...

Pressure Switches

Pressure Switches

A pressure switch is a mechanical or electronic device activated by the pressure of fluids, air, or gas when the fluids, air, or gasses reach a threshold or setpoint. The designs of pressure switches include bourdon tubes, pistons, diaphragms, or...

Pressure Gauges

Pressure Gauges

A pressure gauge is a method of measuring fluid, gas, water, or steam intensity in a pressure powered machine to ensure there are no leaks or pressure changes that would affect the performance of the system. Pressure systems are designed to operate within a specific pressure range...

Level Switches

Level Switches

A level switch is an electrical or mechanical method for measuring the level of a liquid, powder, or granule material. It is designed to activate an alarm if the material level in a container passes a predetermined height or depth...

Pressure Transducers

Pressure Transducers

A pressure transducer is a mechanical device that converts applied pressure, a physical quantity, into a measurable and industry-standard electrical signal which is linearly and proportionally related to the applied pressure...
