Technical FAQs

Q1: What does the PR6426/010-130 measure?
It measures shaft vibration, radial displacement, axial position, and eccentricity.

Q2: Is this a contact or non-contact sensor?
It is a non-contact eddy current displacement sensor.

Q3: What type of machinery is it used for?
It is commonly used in turbines, compressors, pumps, and large rotating industrial equipment.

Q4: Does it require a signal conditioner?
Yes, it is typically used with EPRO signal conditioning modules such as CON021 or equivalent systems.

Q5: What is the measurement principle?
