Frequently Asked Questions

Does the 16699-02-05-03 seismoprobe require an external power supply?

No, the moving-coil design generates its own voltage signal proportional to velocity.

What is the primary benefit of the 500 mV/in/sec sensitivity rating?

It provides a high signal-to-noise ratio for accurate low-frequency machinery vibration measurements.

Can I mount this velocity sensor in any orientation?

You must verify the specific orientation option code to ensure proper internal spring alignment.
