330500-02-00 is a Bently Nevada Velomitor Piezo-velocity Sensor. The 02 option selects an M8 × 1 mounting-thread adapter and the 00 suffix specifies that no agency approval is required.

The sensor is a rugged two-pin integrating piezo-accelerometer intended for absolute vibration measurement on bearing housings, machine casings and structures. The paired 9571-54 identifier denotes the associated cable selection.

• Sensitivity is 3.94 mV per mm/s, equivalent to 100 mV per in/s, with a ±5% tolerance.
• The broad response is 4.5 Hz to 5 kHz within ±3 dB, with a tighter 6 Hz to 2.5 kHz band within ±0.9 dB.
• Velocity range reaches 1270 mm/s peak for high-amplitude machine vibration.
• Transverse sensitivity is less than 5%, and amplitude linearity is ±2% to 152 mm/s peak.
• The hermetically sealed, case-isolated construction supports demanding industrial environments.

• Mount the sensor on a prepared machine surface using the supplied M8 × 1 adapter and the documented installation practice.
• Connect the two-pin sensor to a compatible Bently Nevada vibration monitor and preserve cable shielding and polarity.
• The 9571-54 identifier denotes a 54 ft two-conductor shielded cable selection with the compatible female sensor connector.
• Cable runs up to 305 m are documented with the specified cable type without signal degradation.
• Confirm monitor input type, measurement units and alarm levels before commissioning.

• Absolute bearing-housing vibration on machines with rolling-element bearings.
• Casing and structural vibration measurements expressed in velocity units.
• Machine-condition monitoring where a rugged, case-isolated industrial sensor is required.
• Retrofit replacement of an M8-adapter 330500 sensor and matching field cable.
