Temperature transmitter measures vibration

Theoretically, ordinary displacement or vibration probes generate millivolt signals, and temperature transmitters are capable of measuring such millivolt signals; therefore, if an appropriate range is selected, can a temperature transmitter be used to measure millivolt signals? An old master named Wang said that this would work.
……That’s such a wild idea – it makes me question the very foundations of reality. The liquid level is represented by an analog signal, and pressure and flow rate are also analog signals; so in that case, pressure, liquid level, and flow rate meters can all be used interchangeably
It is possible to measure millivolts, but it must be a temperature-sensitive type without linear compensation functionality; the cold junction temperature compensation circuit may also need to be modified in order to make it practical for use.
Vibration is a variable quantity; what is actually measured is the effective value of the alternating voltage, while temperature changes are measured as a stable direct-current millivolt voltage. What are you joking about?
It’s very certain that you are not a meter technician or an electrician. It can’t even be considered a regular job position
For liquid level and pressure, they are generally equipped with integrated gauges; their sensors and transmitters are inseparable, and there is no distinction between analog and digital signals. Flow rate can be classified by measurement type: differential pressure involves a pressure transmitter, electromagnetic flow meters rely on a small current value, while vortex flow meters typically generate a frequency signal. They can’t be compared; this is a discussion thread, so please keep a humble attitude when discussing. When it comes to imagination, it’s indeed quite extensive; I think the same.
Sorry, I’m a instrumentation technician with extensive on-site experience; my theoretical knowledge is passable. Thank you.
Right. It might be used to measure displacement. Maybe I made a mistake; when measuring displacement, it should logically be a fixed millivolt voltage. I wrote the title wrong. Sorry, let me change that.
It’s possible; I’ll take it apart and examine it when I have the chance to do maintenance later. The unit is currently running, so it’s not easy to check the parameters. It’s possible, but the manufacturing process doesn’t allow it: lol
No, I went to take a look again; it’s about vibration. I’m a bit confused about this too; logically speaking, vibration won’t work. Displacement is understandable, but vibration isn’t. I’ll ask the factory again about the original design – what was the underlying concept behind it. That’s quite imaginative.
The displacement of the compressor in my home is a DC voltage signal, not a voltage in the millivolt range. It’s a rather unconventional idea, so it’s not possible to conduct tests; please reply if you have tried it.
