This standard is essential for engineers, technicians, and operators involved in performance testing, troubleshooting, or benchmarking equipment performance. 3. Core Components of the Standard
A key strength of PTC 19.2 is its detailed guidance on setting up instrumentation and rigorously determining the uncertainty of the pressure measurement itself, which is critical for calculating the overall uncertainty of key performance indicators like power and heat rate. The standard typically covers a broad range of topics, including the selection of appropriate pressure instruments, proper installation techniques, calibration procedures against recognized standards, and protocols for accurate data transmission.

If you are using a remote seal with capillary tubing, the standard still applies to the hydraulic system between the diaphragm and the sensor.
It isn't just a manual for buying a gauge; it’s a deep dive into the methodology, selection, and application of pressure-sensing technology in industrial environments. This standard is essential for engineers, technicians, and
| Type | Definition | Typical Instrument | |------|-------------|--------------------| | | Pressure of a fluid at rest relative to the measuring instrument, measured perpendicular to flow direction. | Wall tap, static pressure probe | | Stagnation (Total) Pressure | Pressure measured when the fluid is brought to rest isentropically. | Pitot tube, impact probe | | Differential Pressure | Difference between two static pressures (e.g., across an orifice plate, filter, or heat exchanger). | Differential pressure transmitter, manometer |
Consistent errors caused by improper calibration or environmental effects. The standard typically covers a broad range of
It is highly probable that the intended designation was (Pressure Measurement), which is part of the fundamental "PTC 19" series used to support other performance test codes.
