It is not too much to say that the managing partners of Principal Technology have a passion for instrumentation and control systems. The best reactor, pump, heater, burner, filter, or separator will not work without properly designed and integrated controls.

Our instrument engineers have decades of experience designing and specifying the right tool for the job in terms of field end devices ranging from standard flow, temperature, and pressure sensors to complex CEMS and Process Analyzer Systems.

Our control system engineers are well versed in most major Control and Automation platforms and can integrate your equipment or plant into an efficient ergonomic control system.

Our experience includes basic process control for continuous and batch plants, process safety systems including ISA S84 Safety Instrumented Systems, burner management systems, reactor control systems, SCADA remote monitoring, and satellite, radio, and cellular mobile platforms.

Continuous Emissions Monitoring Analyzer System

Continuous Emissions Monitoring Analyzer System

Principal Technology Instrument Engineers have experience providing turn-key design and integration services for a variety of process gas analyzer systems including Continuous Emissions Monitoring, process analyzers, flue gas, flare systems, sulfur recovery tail gas, and thermal oxidizers using analyzer technology from Horiba, Honeywell, Ametek, Rosemount Analytical, and Siemens.  

Our typical system can include outdoor rack mount structures or fully enclosed modular analyzer shelters complete with HVAC, purge, and pressurization systems ready to drop in place at your plant. 

Modular Process Control and Safety Control System

Modular Process Control and Safety Control System

PTI engineers and system integration group have the experience to tackle small stand-alone packaged control systems to large-scale plant-wide automation systems.  This project included both the safety shutdown system and the process control system integrated into a single modular e-house that housed the unit’s motor control center.  The system was designed and fabricated in Plano, Texas, and shipped to the end-user.  

The pre-shipment Factory Acceptance Testing (FAT) included a fully hardwired function test and design review with our client’s engineering, operations, and maintenance stakeholders.  The extensive design review and off-site function test reduced the installation and commissioning time by over 50% and minimized the on-site congestion during the project’s construction phase.

Safety PLC Based Burner Management System

Modern Safety PLCs provide a unique combination of flexibility to interact with a plant’s DCS or Process Control System while maintaining the security and safety functions required for Burner Management and Flame Safeguarding traditionally provided by stand-alone control units.  

National Fire Protection Association (NFPA) standards for Fluid Heaters (NFPA 87) and Ovens and Furnaces (NFPA 86) include requirements for Safety PLCs used in these systems.  

PTI’s project portfolio includes numerous projects for applying these standards to new equipment construction as well as control system upgrades of legacy heaters and furnaces.
