Products

We serve the oil and gas, power and nuclear industries with precision instruments that measure pressure, level, temperature and flow. No company builds a better product, and no company backs their products with better warranties or better customer service. SOR products are the standard for quality, reliability and durability.

One reason for our continued worldwide growth is the willingness to listen to our customers’ specific needs and develop customized solutions to meet those needs. In fact, a majority of the products SOR manufactures and delivers are specially engineered to order. New products continue to be engineered and developed that integrate features such as wireless and smart technologies.

There are SOR instruments built decades ago that are still in the field, in the harshest environments, doing their jobs every minute of every day. In 1993, SOR earned the highest level of quality registration – ISO:9001 – and we’ve continued to achieve that goal every year since. Quality is the hallmark of our products.

Products with Adaptability

Pressure

SOR pressure transmitters are designed for use in hazardous conditions and hostile environments. Their rugged and compact design provides an instrument perfect for use in tough locations where space is limited. The recently introduced 815PT smart pressure transmitter with HART®7 and ModBus® RTU is just one example from the 800 series of how SOR is bringing technology and durability together.

When it comes to pressure switches, one size does not fit all. SOR will engineer a pressure switch to meet your individual needs using components such as switching elements, diaphragm systems and pressure ports specifically selected for your application. The Mini-Hermet – explosion proof pressure/compound pressure switch provides the trusted SOR pressure sensing assembly hermetically sealed in an explosion proof steel capsule.

Known as one of the most flexible products, SOR differential pressure switches are available in weatherproof and explosion proof configurations to best match the application. Most models are safety certified to IEC 61508 (SIL) for non-redundant use.

Temperature

SOR manufactures a complete line of temperature sensors which includes thermocouple elements, Resistance Temperature Detector (RTD) sensors, thermowells, sample probes, industrial assemblies, and specialty temperature sensors. SOR has the industrial experience, technical expertise, and facilities to accommodate demanding temperature sensor requirements as well as general purpose requirements. With quality performance and durability in mind there is 100% testing of elements for accuracy, and assurance that includes a wide variety of NDE testing in-house abilities. High purity mineral oxide insulation and high temperature stainless steel sheaths are standard on thermocouples. SOR can engineer to order the best solution for your application. Tens of thousands of our high pressure sensor assemblies have been used in the oil and gas industry since their introduction.

SOR temperature switches are built to handle temperature extremes, corrosive process media and the most unfriendly environments. With all models featuring 316SS sensing bulbs, set point adjustment with calibration scale and a three-year warranty, these temperature switches are not only economical, but built for the long haul providing a low cost of ownership. They come calibrated to your set point at no extra charge and are ready to install with no special tools required. SOR products can be engineered to order with a multitude of options, accessories, and agency approvals, offering the best solution for your unique application.

Level

Adaptability is a good quality to have when it comes to measuring process level. SOR level switches can be engineered specifically for your application by varying the switch type and number, housing, chamber material, process connections and other accessories.

SOR also offers a comprehensive line of level transmitters. Whether you need a submersible level device, non-contact ultrasonic transmitter or continuous output RF probe, SOR has a solution.

Flow

SOR manufactures several distinct flow technologies to meet the needs of the specific application. Vane-operated switches work magnetically to sense the flow of liquid, while thermal differential switches offer a more flexible solution with no moving parts.

While a fluid is flowing through a pipe, the flow rate can be calculated by measuring the changes in fluid pressure. Applying a differential pressure transmitter, like the 815DT smart differential pressure transmitter, for flow rate measurement is one of the most common installations.

Nuclear Qualified

It’s a familiar situation at older nuclear power plants – the switch that was made years ago is no longer available. Relax. SOR can design and build 1E-qualified pressure, differential pressure or temperature switches that will get the job done.

Systems

SENSOR closed loop Sampling Systems are specially designed and manufactured for the chemical hydrocarbon processing industry to mitigate potential hazards that exist with extracting representative grab samples. They are designed and constructed to meet the industry requirements for environmental and emissions standards. Manufactured in Houston, the heart of the industrial Gulf Coast in Texas, Sampling Systems are required to manage quality, yield and other important aspects of chemical and hydrocarbon processes.
