Features:
- Exact 330400-02-05 three-wire accelerometer with 100 mV/g sensitivity and 50 g peak range.
- M8 x 1 integral stud mounting option with a 3-pin MIL-C-5015 electrical connection.
- Multiple approvals (CSA, ATEX and IECEx) as encoded or retained by the complete order suffix.
The 330400-02-05 is a case-mounted 330400 accelerometer intended for critical rotating-machinery applications where casing acceleration is required, such as gear-mesh monitoring. Its 100 mV/g sensitivity, 50 g peak range, 10 Hz to 15 kHz ±3 dB response and isolated stainless-steel case must be matched to the configured monitoring channel.
This execution uses the M8 x 1 integral stud option. The approval suffix is Multiple approvals (CSA, ATEX and IECEx). Before replacement, confirm the complete nameplate, mounting thread and surface finish, 4.1 N·m torque requirement, three-pin connector, -24 V DC excitation, cable shielding and channel scale. After installation, verify output bias and measured response before returning protection or monitoring functions to service.
The 330400-02-05 Bently Nevada 330400 Three-Wire Piezoelectric Accelerometer may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: The official 141638 Rev. AB datasheet defines the 330400 accelerometer and 130539, 16925 and 16710 cable ordering families. Confirm the complete part number, supplied marking, receiving hardware and required accessories before replacement.
The 330400 converts casing acceleration into a nominal 100 mV/g signal across a 50 g peak range. Its published response is 10 Hz to 15 kHz ±3 dB, with a 30 Hz to 10 kHz ±10% band; preserve the receiving-channel scale and alarm configuration.
The 330400-02-05 uses a M8 x 1 integral stud. Prepare the mounting surface to the documented finish, apply the approved 4.1 N·m torque and position the case so the cable connection is protected from strain and moisture.
Use the three-pin MIL-C-5015 connection with -24 ±0.5 V DC excitation and nominal 2 mA bias current. Confirm the expected -8.5 ±0.5 V DC output bias, shield path and connector sealing before signal testing. The 05 code selects multiple approvals (csa, atex and iecex).
