Bently Nevada 330525-01 Ruggedized Piezo Velocity Sensor

Product Description

The Bently Nevada 330525-01, also cataloged as the 330525 piezo velocity sensor, converts machine-housing vibration into a conditioned velocity output for vibration monitoring. The sensor uses a specified sensitivity, frequency response, bias supply, and output impedance to interface with the receiving monitoring channel.

Hardware Specifications

Piezo Velocity Signal Characteristics

The 330525-01 measures absolute machine vibration at its mounting location and produces a velocity-related electrical output. The nominal sensitivity of 3.94 mV per mm/s defines the relationship between vibration velocity and sensor output.

The specified 4.5 Hz to 2 kHz frequency response defines the stated measurement band. Therefore, the receiving monitoring channel should use scaling and filtering that match this documented response.

Transverse sensitivity remains below 5%, while amplitude linearity remains within +/-2% through 152 mm/s peak. These specifications define the sensor response under the stated measurement conditions.

Frequently Asked Questions

Q: What supply voltage does the 330525-01 require?
A: The supplied specification lists a -22 to -30 VDC supply range with a 2.5 to 6.0 mA bias current.

Q: What output bias does the sensor provide?
A: The output bias is -12 +/-3 VDC, referenced to pin A. The receiving input should accommodate this electrical operating point.

Q: Can the 330525-01 directly replace another Velomitor sensor?
A: Not solely based on physical similarity. Verify sensitivity, supply requirements, frequency response, connector and cable arrangement, and the exact approval marking before substitution.

Field Installation Guidelines

Mount the sensor at a machine location that mechanically transmits the vibration being monitored. The mounting surface should provide firm mechanical coupling without introducing unnecessary movement between the sensor and machine housing.

Route the mating cable separately from sources of strong electrical interference where practical. Maintain the specified connector and cable arrangement, and inspect the connector interface before energizing the circuit.

Connect the receiving channel according to the documented sensor pin assignment. Verify the input scaling against the 3.94 mV per mm/s nominal sensitivity and confirm that the input circuit accommodates the -22 to -30 VDC supply range, bias current, and output bias.

For machinery monitoring, check the sensor orientation and mounting direction against the measurement point definition. Also verify that the selected sensor approval matches the installation area. The CSA/NRTL/C option listed for this model does not by itself establish approval for every hazardous-area classification.

Do not infer missing dimensions, weight, operating temperature, or power-consumption values from similar Bently Nevada sensors. Use the delivered product documentation when those parameters are required for installation or enclosure calculations.
