Regarding the signals of vibration measuring instruments
Thread Content
Besides 4-20MA, are there any vibration measurement instruments with digital output as well?
Vibration is relatively complex; I’m not sure if you have a transmitter?
Reply 2# backhamm1982 There are some； But I think whether it’s there or not, in the end it’s not a big issue that the signal regulator outputs 4-20. I’m asking about those with HART, or in other words, those who have used them before. species
Check the manual – the vibration meter outputs a frequency signal, which must be converted into a standard signal using a transmitter! As for whether to use HART for debugging, I haven’t tried it yet! It should be adjusted using a micrometer and a multimeter!
What does it mean to output a ‘frequency signal’?
Vibration is a frequency signal; to check the installation position of the vibration probe, use a multimeter to measure the voltage signal, which is generally between 9 and 11 V
Are you referring to the HART strap with a 2-wire system?
