Are the pressure gauges connected to the inlet and outlet buffer tanks of the compressor and mounted on the dashboard classified as Class A gauges?

As the title suggests: Some say it counts as a Class A gauge during operation, while others say it doesn’t. Does a longer pressure transducer mean it is no longer considered a gauge of the main unit?
The classification into categories A, B, and C is primarily based on the parameter requirements of the pressure gauges used in the field. Generally, pressure gauges installed on boilers and pressure vessels related to production safety must undergo mandatory calibration according to category A standards. Category B is used in situations where accuracy of pressure parameters is required at the production site, while category C is generally used for rough indication of whether a system is under pressure or not; such gauges can be recalibrated during maintenance of the associated equipment.
Our company names its Class A tables by itself; those are the key and most important ones, while the rest fall under Class B
