FAQ

Q1. Is “330500-06-02” a proximity probe (eddy-current) or a vibration sensor?

Despite “proximity” sometimes being used loosely, the 330500 series is a piezoelectric

 velocity / vibration sensor (Velomitor). It senses casing vibration

rather than shaft displacement.

Q2. What does the “-06-02” suffix mean?

The “-06” often refers to the mounting thread / adapter, e.g. “-06: 5/8-18 UNF thread” in some listings. 

The “-02” may denote a particular agency approval / certification (for e.g. ATEX /

hazardous area compatibility) in that variant. 

Q3. How do I mount the sensor?

Use a rigid, clean, smooth mounting surface on the bearing housing or structural casing.

Improper mounting can degrade amplitude and frequency response. 

Torque the mounting properly (24–40 in-lb). 

Q4. What range of vibration signals can it detect?

Useful within ~4.5 Hz to 5 kHz (±3 dB) band. 

Up to ~1270 mm/s (50 in/s) peak velocity.
