pressure difference
Thread Content
I would like to ask fellow sailors: is the pressure difference an analog or digital value?
The pressure difference referred to in general is an analog value, which is the difference between two pressure transducers or the difference in pressure between the positive and negative chambers of a differential pressure transmitter.
But isn’t the pressure difference value a quantity that changes continuously over time?
If you want an analog value, then the pressure difference will be in analog form; if you want a digital value, then the pressure difference will be in digital form. You’re the boss here – everyone looks to you for guidance. Trying to deceive you is like acting like a dog {:3_51:}
The differential pressure value changes as it should; it has nothing to do with time at all. You’re lying – do you need me to issue a certificate? Bro, go to the police station.

Are you asking what signal the differential pressure sensor outputs? It seems I’ve never seen a differential pressure transmitter that outputs digital values
May I ask, how long have you been working in the instrumentation field?
The pressure difference is a quantity that changes continuously over time, and there is a conversion relationship between the displayed flow rate and the liquid level and pressure.
On our instruments, only electrical signals have analog and digital forms; it’s just a difference in the type of signal
Whether it’s pressure difference or differential pressure – once the pressure signal reaches the DCS, it’s up to you to decide how to process it
