Limit Switches
Limit switches play a simple but important role in process instrumentation. Once contact is made with them, they automatically prevent a material or liquid from advancing any further. Limit switches are typically controlled by an actuator and are often encased in plastic to prevent damage from caustic materials. Because of the diversity of products available, limit switches are an essential component of a number of different industrial control processes.
As an authorized distributor of industrial controls by Dwyer, Westlock and more, SEMCOR has many options available for anyone in need of limit switches or related products.
Digital, Analog and Test Gauges
Industrial gauges measure temperature, pressure and other factors with accuracy and high degrees of repeatability. Gauges can be digital or analog, and either permanently installed in a specific location, internally with the fluid or external to the pipe, or used for testing purposes.
ReoTemp carries a full line of temperature and pressure gauges. Badger Meter is a well known manufacturer of flow meters for liquids, gas, or steam using a variety of technologies.
Dwyer Instruments has been a manufacturer of gauges for industrial processes since 1931. The company now controls the Love and Mercoid brands, too, making them one of most comprehensive gauge manufacturers on the market today. SEMCOR is proud to be a partner to all companies in the Dwyer family.
Transmitters and Transducers
Industrial transmitters/transducers convert pressure generated by a gas or a liquid into an electrical signal, allowing levels to be monitored remotely. This is a critical task in large industrial processes, where early intervention is essential to preventing downtime.
Various types of pressure transmitters are available, including instruments for measuring differential pressure and other sophisticated tools. Contact SEMCOR directly for more information about our current inventory of products by Dwyer, ReoTemp, Badger, and other leading manufacturers.
Industrial RTDs and Thermocouples
Resistance temperature detectors (RTDs)Â are sophisticated temperature gauges that provide accurate measurements with low drift across a wide operating range. Thermocouples are a similar technology that is generally less stable but is smaller, responds faster and is capable of operating in higher temperatures.
SEMCOR supplies both thermocouples and RTDs by SensorTec and ReoTemp, two of the most sophisticated manufacturers on the market today. Contact us for help choosing the right tool for the job.
Measurement Devices for Process Monitoring
Accurate measurement is the foundation of any control system. SEMCOR provides a wide selection of instruments designed to monitor temperature, pressure, flow, and other process variables. These devices are available in multiple configurations, including panel mounted, inline, and portable options. Whether a facility needs rugged field instruments or precision tools for controlled environments, we supply products that support consistent readings and dependable performance.
Switching and Actuation Components
Switching devices play an important role in automated process control. Components such as limit switches, position indicators, and mechanical triggers help operators maintain safe operating conditions by signaling when equipment reaches a defined point. These devices are built to withstand exposure to chemicals, vibration, and temperature fluctuations, making them suitable for a wide range of industrial settings.
Signal Conversion and Communication Tools
Transmitters and transducers convert physical measurements into electrical signals that can be monitored remotely or integrated into plant wide control systems. Options include models designed for differential pressure, temperature, and flow applications. SEMCOR supplies instruments that support analog and digital communication protocols, allowing seamless integration with PLCs, SCADA systems, and distributed control networks.
Temperature Sensing Technologies
Temperature measurement is a key requirement in many industrial processes. SEMCOR offers RTDs, thermocouples, and related accessories from leading manufacturers. RTDs provide stable, repeatable readings across a broad temperature range, while thermocouples offer fast response and compatibility with high temperature environments. Our team assists customers in selecting the right sensing technology based on accuracy needs, installation conditions, and material compatibility.
Control Devices and Calibration Equipment
Industrial controllers, indicators, and calibration tools help maintain process stability and verify instrument accuracy. SEMCOR supplies single loop controllers, handheld calibrators, flow indicators, and other devices used to fine tune system performance. These tools support commissioning, troubleshooting, and routine maintenance across a variety of industries.
Application Support and Product Selection
Every facility has unique process requirements, and instrumentation must be selected with those conditions in mind. SEMCOR provides guidance on product compatibility, installation considerations, and long term maintenance needs. Our team helps customers evaluate environmental exposure, signal requirements, mounting options, and system integration to ensure each component performs reliably within its application.
