200355-00-00-00 is a Bently Nevada low-frequency accelerometer for casing vibration measurements that need response down to 0.2 Hz. The exact order code specifies the standard 1/4-28 stainless-steel stud with brass tip, 100 mV/g sensitivity and no approval option.

Its two-pin MIL-C-5015 top-exit connector and IEPE-style constant-current excitation differ from the three-wire, negative-supply arrangement used by the 330400 and 330425 family.

• Measures low-frequency through high-frequency casing acceleration from 0.2 Hz to 10 kHz.
• Provides a 100 mV/g signal with a ±50 g measurement range.
• Supports condition monitoring on machinery where slow structural vibration must be retained.
• Uses a two-wire constant-current interface with an 8–12 V DC output bias.

• Prepare a rigid 1/4-28 mounting location and follow the documented surface and torque requirements for 200355-00-00-00.
• Use a compatible two-pin MIL-C-5015 cable and a monitor channel that supplies the specified constant current.
• Keep high-energy and variable-frequency-drive cables separated from the sensor route.
• Confirm output bias, sensitivity scaling and low-frequency alarm filtering before service.

• Low-speed machinery casing vibration
• Fans, pumps and structural monitoring
• Condition-monitoring acceleration channels
