Circuit 03
Process controls and calibration
Instrument calibration for temperature, pressure, flow and level, plus instrument installation, tubing and control system work.
DuCom calibrates instruments for temperature, pressure, flow and level. DuCom is certified, and all of our calibration instruments are NIST traceable.
Installation and tubing
We also install the instruments themselves, along with the impulse tubing and the pneumatic supply tubing to control valves, so the field side of a control loop comes from one contractor.
Controls work
- PLC and HMI systems
- Process instrumentation and field devices
- Control panel design and integration
- Controls troubleshooting
- Preventive and corrective maintenance
- Control system upgrades and changes
From the field instrument to the control panel and the operator screen, we look at how each part works within the process. That helps us design practical controls and find faults quickly.

Our work
What instruments do you calibrate?
We calibrate instruments for temperature, pressure, flow and level, and our calibration instruments are NIST traceable. We also install instruments, impulse tubing and the pneumatic supply tubing to control valves.
How do you test new electrical work before start-up?
Every conductor from 120 to 15,000 volts is megger tested after installation, and conductors over 600 volts are hi-pot tested before they are energized. Loop checks and simulations follow, so start-up holds no surprises.
