Bentley piezoelectric vibration probe usage
Thread Content
I would like to ask the experts: Can the Bentley piezoelectric vibration probe be connected directly to the active AI channels of a PLC or DCS, without the need for Bentley’s dedicated analog I/O card? Thank you
What model? Bentley or some other model with a current transmitter?
330500 and 330530 piezoelectric velocity sensors
Of course this won’t work; the signal from the sensor at the site must be received by its transmitter, which then converts it into a 4-20mA signal or a communication signal. Is it similar to being able to connect the sensing element of an on-site split-type electromagnetic flowmeter directly to your control system? The principle is the same
Judging from this model of yours, it should be for measuring shell vibration
Well, is it appropriate to use piezoelectric vibration probes to measure the vibrations of the bearings in the horizontal and vertical directions of the power station fans? What about using an eddy current probe? Which one is better? Thank you
Yes, the same question about how to use this probe
No, it must be used in conjunction with the 42 series cards of the Bentley 3500 vibration analyzer; it can be configured to output either the amplitude or the velocity of the vibration values
It seems it doesn’t work; the signal is special
No, the operating voltage of the Bentley probe is +10V to -10V; it needs to go through a 3500 converter in order to produce a 4–20mA output, so it cannot be connected directly to the DCS card.
