Controlled duty
Review sensing principle, insertion, diaphragm, branch geometry, orientation, seal, calibration access, drainability, cleaning exposure and failure containment for each product-contact instrument connection. The review must also reconcile measured variable and response-time requirement with process and cleaning pressure-temperature range across normal, transition and fault conditions.
- Measured variable and response-time requirement
- Process and cleaning pressure-temperature range
- Required result and acceptable operating range
