Do you develop custom process control systems?

Yes. We are a full service automation and instrumentation supplier. Our engineering team can design, program, install, integrate and startup control systems, SCADA, HMI’s and all other custom types of process automation. We work with all the common process controls platforms, including Siemens, Rockwell, Wonderware, Intellulation and more.

We’ve been developing process controls and instrumentation for over half a century. Contact Durkin today to discuss your automation needs or being planning your next automation project.

Do you only carry the brands listed?

We carry a wide-range of process instrumentation and solutions. You can see our full supplier list here, but we may be able to source brands or point you the right distributor. More importantly, we can help you determine the appropriate instrumentation and controls solutions needed to solve your process issues. Talk to one of our experts today: (314) 432-2040 or fill out a contact form.

Which controls strategy or recorder is best for my situation?

  • What automation currently exists in your plant?
  • What is your flow rate, your chemical composition, and other physical product qualities?
  • What is your goal in adding process automation or recorders?
  • What kind of instruments are already on your line?

The answers to these and other questions will help us determine the right recorder or controls strategy for your line. Every situation is unique, and a one-size fits all solution does not exist.

Durkin’s process specialists can help you determine the specific recorder and/or controls strategy appropriate for your situation. We evaluate your line and existing equipment, then design a quote and plan around your process goals. Call (314) 432-2040 or contact us to begin this process today.

What is a process recorder?

Process recorders measure, monitor and register tasks, process parameters, maintenance, optimization, troubleshooting, and other process line information. Recorders communicate this information with controllers, which allows for visualization of line data for line operations, plant managers, and other personnel.

We carry several different process recorders and controllers and offer full integration and automation services for integrating these into your lines. Contact Durkin (314) 432-2040 to get started.

What are process controllers?

Process controllers monitor and control aspects of process systems inside manufacturing plants, including temperature, flow rates, pressure, and other operating inputs. They are key to automating industrial processes and providing remote control of processing equipment.

Durkin carries a full selection of process controllers and we offer full integration and automation services for integrating these into your plant. Contact us (314) 432-2040 to get started.
