Bently Nevada 330425-01-00 Accelerometer Acceleration Transducer

The 330425-01-00 acceleration transducer provides reliable vibration monitoring for heavy industrial machinery.

It uses a hermetically sealed 316L stainless steel case to withstand tough operating environments.

This sensor features a 100 mV/g sensitivity level for accurate and consistent acceleration measurement.

Its wide frequency response supports dynamic vibration analysis across many mechanical applications.

The unit works with -24 Vdc power and maintains stable output under varying thermal conditions.

Strong shock resistance and high immunity to magnetic interference ensure long service life.

you install it properly, the sensor delivers precise data without signal distortion or noise interference.

The 330425-01-00 accepts mounting in any orientation to fit different equipment layouts.

The 330425-01-00 has a sensitivity of 10.2 mV/m/s² (100 mV/g) with a ±5% tolerance range.

It measures acceleration up to 490 m/s² (50 g) peak within a 10 Hz to 15 kHz frequency span.

Vibration above 15 kHz may reduce the effective measurement range near the transducer’s resonance.

Amplitude linearity stays within ±1% up to the full 490 m/s² peak acceleration rating.

Broadband noise floor measures 0.039 m/s² (0.004 g) rms from 10 Hz to 15 kHz.

Frequency response reaches ±3 dB from 10 Hz to 15 kHz and ±10% from 30 Hz to 10 kHz.

Temperature sensitivity varies -11% to +3% over the full operating temperature range.

Transverse sensitivity remains below 5% of the axial sensitivity value during normal operation.

Mounted resonant frequency exceeds 30 kHz with a maximum resonant peak of 20 dB.

Base strain sensitivity differs based on serial number and the use of a mounting base.

Maximum supported cable length extends to 305 meters with no signal quality loss.

The sensor uses -24 ±0.5 Vdc input voltage with a nominal 2 mA bias current.

Output bias voltage stabilizes at -8.5 ±0.5 Vdc with an isolated case design.

Operating and storage temperature spans -55°C to +121°C for extreme industrial environments.

Shock survivability reaches 49,050 m/s² (5000 g) peak without permanent damage.

Relative humidity tolerance is 100% condensing, as the case is fully hermetically sealed.

Magnetic field susceptibility stays below 2.21 mm/s²/gauss at 50 gauss and 50–60 Hz.

The sensor body carries an IP68 rating for dust-tight and watertight performance.

The 330425-01-00 weighs 99 g without a cable and uses 316L stainless steel construction.

It has a diameter of 23 mm and a total height of 59 mm including the mounting stud.

A 3-pin MIL-C-5015 connector provides secure and reliable electrical connection.

Mounting thread uses a ¼-28 UNF integral stud with a required torque of 4.1 N·m.

Mounting surface finish must be 32 micro-inch rms for optimal mounting stability.

Select a clean, flat mounting surface on the equipment you want to monitor.

Prepare the surface to a 32 micro-inch rms finish for proper sensor seating.

Mount the 330425-01-00 using the ¼-28 UNF integral stud at 4.1 N·m torque.

For older units without a “G” serial prefix, use the mounting base to lower strain sensitivity.

Connect the 3-pin MIL connector to the matching cable and secure all connections.

Apply -24 ±0.5 Vdc power and confirm the bias voltage reads -8.5 ±0.5 Vdc.

Mount the sensor in any orientation that fits your equipment layout and monitoring needs.

Route the cable away from high-noise sources to preserve clean vibration signals.

Do not exceed the rated temperature or shock limits during operation and handling.
