Handheld Vibration reading device

Handheld Vibration reading device

Handheld Vibration reading device

Hello everyone,

Can anyone recommend a make & model of a handheld device that we can purchase to take vibration readings on process piping in the refinery that I work in? We need something that can read low enough for typical low frequency pipe vibrations, I see that some Fluke models are limited to 10hz which doesn't seem low enough.

RE: Handheld Vibration reading device

So how low in frequency do you need? Guessing games don't appeal. If you want to find out get a scope and look at the waveform from a strain gage accelerometer with DC coupling. Piezos often have a 3 Hz high pass.

RE: Handheld Vibration reading device

Do you want overall vibration levels only?
What unit do you want acceleration, velocity, displacement?
Do you need spectrum?
What is minimum frequency?
What is maximum frequency?
What sensor type: accelerometer, velometer, other?
What are sensor temperature limits, mounting type, and access (thermal insulation)?
Do you need just single axis sensor or triaxial?
How will data be recorded: time series recording, spectra, overall levels?
What is final data format: spreadsheet, plots, other?

This job may not be as easy as you or your boss thinks it is or should be!


RE: Handheld Vibration reading device

How low do you need to go?

Can you set your device to have a long sample time and review the waveform? Is your device using the right sensor for low frequencies?

If you want a simple handheld that gives overall readings only, we've used Balmac handheld and they are quite sensitive to lower frequencies.

Avoid any/all of the newer devices that run on the ultra low power accelerometers. They are great devices for some things but only detect vibration above 20Hz.

RE: Handheld Vibration reading device

What problem are you in search of?
- Pipe failures?
- Noise?
- Some pipes' vibration looks frighteningly high ?

RE: Handheld Vibration reading device

Are you proceeding with this project?
If yes, then what are you doing?

RE: Handheld Vibration reading device

Good luck on finding something affordable that can measure less than 10 Hz. That's where it gets expensive.

On the other hand: greater than 10 Hz opens the door to some affordable models. I have one by M&A Instruments.....and it's pretty good. (For something that was about $300.)
