Features:
- Sensor architecture: an integrating piezoelectric element and embedded electronics provide a native velocity signal.
- Measurement perspective: the sensor measures absolute vibration relative to free space at the machine surface.
- Machine fit: the 330500 family is designed for condition monitoring where velocity units are useful on rolling-element-bearing machinery.
Selection decision: Use the sensor where bearing-housing, casing, or structural motion provides a meaningful view of machine condition.
Interface decision: Evaluate the monitor input, signal bias, polarity, and cable as one measurement chain.
Application decision: Confirm that the chosen mounting point transmits the rotor behaviour that the monitoring strategy is intended to observe.

- Native measurement: embedded electronics convert the piezoelectric element response into a velocity output at the sensor.
- Bias reference: output bias is -12 +/-3 VDC over temperature, referenced to Pin A.
- Grounding: case-isolated construction helps separate the sensor body from the signal reference.
- Noise floor: broadband noise is 0.004 mm/s rms nominal over the 4.5 Hz to 5 kHz band.
- Adapter scope: the first 00 code means no mounting-thread adapter is supplied with this configuration.
- Mounting load: the manufacturer specifies 32-46 kg cm (24-40 in-lb) maximum mounting torque.
- Orientation: solid-state construction supports vertical, horizontal, or another suitable mounting angle.
- Environmental seal: the hermetically sealed case is rated for 100% relative humidity when not submerged.
- Connector polarity: motion toward the connector makes Pin A positive with respect to Pin B.
- Cable reach: up to 305 m of manufacturer cable 02173006 is specified without signal degradation.
- Recommended length: 63 m is the stated recommendation under the datasheet's 50 g, 10 kHz, and 200 pF/m cable assumptions.
- Channel setup: confirm the receiving input supports the sensor's negative bias and 100 mV/in/s velocity scale.
- Rolling-element machinery: supports velocity-based condition monitoring on machines with rolling-element bearings.
- Bearing housings: measures absolute vibration at rigid bearing-housing locations.
- Machine casings: provides casing-velocity data where the structure transmits useful rotor behaviour.
- Structural monitoring: suits fixed structural points where vibration in velocity units supports trending and protection decisions.
