| Pitfall | Consequence | Free Fix |
| :--- | :--- | :--- |
| Mixing AC/DC in same conduit | Electrical noise on 4-20mA loop | Run separate conduits or use shielded cable |
| Mounting transmitter above hot pipe | Oil migration from diaphragm | Remote mount with capillary |
| No grounding on mag meter | Zero flow reading | Install grounding rings upstream/downstream |
| Using PTFE gasket on steam | Blowout at 400°F | Use spiral-wound graphite |
| Over-lubricating valve stem | Attracts dust, damages packing | Dry film lubricant (never grease) |
Instrumentation work often places technicians in proximity to hazardous processes. | Pitfall | Consequence | Free Fix |
Actuators
Digital Valve Controllers (DVC) – enable stroke monitoring, friction detection, and partial stroke testing for ESD valves.
Smart positioners (e.g., Fisher DVC, Siemens PS2, Samson 373x) enable: Actuators
