Frequently Asked Questions (FAQ)

What makes this 8mm probe more robust?

The 8mm design provides thicker encapsulation for the coil and a stronger stainless steel case. It better resists physical abuse.

What is the FluidLoc cable feature?

It prevents oil or other liquids from traveling through the cable's interior and leaking out of the machine casing.

What is the recommended gap voltage for vibration measurement?

Set the probe gap to achieve approximately -9 Vdc output, which is about 1.27 mm (50 mils) from the target.

Is this probe pressure sealed?

Yes, it uses a Viton® O-ring to seal differential pressure between the tip and case. For tested seals, please contact custom design.

What cable length is this model?

The suffix 10 indicates a total probe and cable length of 1.0 meter (3.3 feet).
