ABOUT oUR INSTRUMENTATION & CONTROLS SERVICES
If your process can't be measured or monitored, it can't be Trusted
Southern Industrial Service installs, calibrates, and commissions the instruments, control panels, security, and network systems that keep your process connected, visible, and running to spec.
Bad electrical work doesn't show up until it fails.

Power problems stop everything at once
A tripped MCC or a failed transformer doesn't just take out one piece of equipment — it can take the whole area, or the whole plant, off-line with it.
Electrical risk is people risk
Arc flash, improper grounding, and unlabeled panels put your crews at risk every time someone opens a cabinet. This isn't work to hand to the lowest bidder.
An inspection will find shortcuts
NEC code, insurance audits, and your own safety team all catch what was installed wrong the first time — usually at the worst possible moment.
field instrumentation
The instruments that tell you what your process is actually doing.
Instrumentation Installation
Field instruments mounted, wired, and connected to spec.
Calibration
Instruments calibrated and documented against process requirements.
Loop Check
End-to-end verification that a signal reads correctly from the field to the control system.
Start-Up Assistance & Troubleshooting
Installation of motor control centers and switchgear that control and protect the loads across your plant.
Control Panel, DCS & PLC Installation, Programming & Testing
Setting and connecting transformers sized and rated for your facility's load.
Tubing Installation & Testing
Process tubing installed and pressure-tested for instrument air and sensing lines.
Analyzer Installation & Testing
Process analyzers installed, connected, and verified for accurate readings
Instrument Stand Fabrication & Installation
Custom stands fabricated and set to mount instruments securely in the field.
Beyond individual instruments, we design, build, and retrofit the panels and skids that house your automation — fabricated to fit your process and your footprint.
Built and integrated panels for automated process control
Marshalling Cabinets
Cabinets organizing field wiring before it reaches the control system.
Insulated enclosures
Climate-protected enclosures for sensitive equipment in harsh environments.
Electrical control panels
Custom-built panels housing the controls for a specific process or piece of equipment.
Retrofit Solutions
Upgrading existing panels and systems to current standards without a full replacement.
HMI enclosures
Enclosures housing operator interface hardware in the field.
PLC & DCS systems
Integration of programmable logic controllers and distributed control systems into your automation architecture.
Process system skids
Pre-built skids integrating instrumentation and controls for a self-contained process package.
Physical security is part of process control
knowing who's on-site, where, and when. We design and install the systems that give you that visibility.
Security technology that covers who and what moves through your site.
Video Survelliance
Camera systems covering critical areas, perimeters, and points of access.
Access Control
Credentialed entry systems managing who can get into a building or area.
Gates, Turnstiles & Barriers
Physical access points controlling vehicle and pedestrian entry to the site.
Intrusion Detection
Sensors and alarms that flag unauthorized entry to a protected area.
Specializing in IP-based systems and applications, we design and install the network infrastructure that carries your automation, security, and communications data across the site.
The IP Network Tying Your Systems Together
Industrial automation
Networked infrastructure supporting plant-wide automation systems.
IP Telephony
Voice communications carried over the same IP network as your data.
LAN/WAN design & configuration
Local and wide-area network design and configuration for site-wide connectivity.
Structured cabling & fiber optics
Cabling infrastructure built to carry data reliably across the facility.
Public address & general alarm (PAGA)
Site-wide notification systems for operational and emergency communications.
Wireless (Wi-Fi, microwave, mesh)
Wireless network coverage for areas where running cable isn't practical.
SOUTHERN INDUSTRIAL SERVICE
A contractor that connects your process, not just your panels.
SAFETY-FIRST CREWS
Every job runs under the same safety discipline, whether it's a routine install or an emergency callout.
ONE CONTRACTOR, EVERY DISCIPLINE
Electrical work coordinates directly with our mechanical, civil, and instrumentation crews — no gaps between contractors to manage.
BUILT FOR URGENCY
Corrective and emergency repair crews are staffed to respond fast when a failure can't wait for a scheduled visit.
Whether it's a planned commissioning project or a loop that just failed, the process is the same three steps.
Getting instrumentation & controls work done, without the back-and-forth.
TELL US WHAT'S GOING ON
Call or request a quote with the scope, the systems involved, and any constraints — a live process, a shutdown window, a hard start-up date.
WE SCOPE IT ON-SITE
Our team reviews your P&IDs and loop lists, walks the job, and gives you a clear plan and schedule before anyone touches an instrument.
OUR CREWS EXECUTE
Installation, calibration, programming, or repair — done to spec, on schedule, with documentation so your data can be trusted.
