+86 15359408275Low-Frequency 100 mV/g Accelerometer with M8 Mounting Stud · Bently Nevada 200155 Accelerometer
Bently Nevada 200155-18-CN is a low-frequency 100 mV/g accelerometer configured for fin-fan and slow-rotating-shaft vibration monitoring.
Mounting option 18 supplies a 3/8-24 to M8 x 1 hex plate stud, while the sensor supports a 2 to 10,000 Hz response and +/-20 g measurement range.
Confirm the CN country execution, M8 mounting surface and torque, five-pin cable, low-frequency monitor channel, output bias and approvals before replacement.

Bently Nevada 200155-18-CN is a low-frequency accelerometer for fin-fan and slow-rotating-shaft casing-vibration applications using a compatible low-frequency acceleration-to-velocity channel.
Bently Nevada 200155-18-CN has nominal 100 mV/g sensitivity, a +/-20 g measurement range and a documented 2 to 10,000 Hz sensor response.
Bently Nevada 200155-18-CN uses a 3/8-24 to M8 x 1 hex plate stud under option 18; the mounting surface, thread engagement and torque must match the installed machine.
Bently Nevada 200155-18-CN has a low-frequency response and longer settling time, so replacing it with a 200150 can produce incorrect system behavior unless the monitor channel and application are re-evaluated.
Bently Nevada 200155-18-CN requires the documented 4.7 to 5.5 VDC excitation, five-pin connection, compatible cable and a low-frequency ProTIM, DSM or System 1 channel.
Verify mounting torque, cable sealing, output bias, noise, polarity and controlled low-frequency response before accepting Bently Nevada 200155-18-CN.
Provide the complete Bently Nevada 200155-18-CN label, mounting and connector photos, monitor channel, country requirement, quantity and destination.
Send the complete 200155-18-CN catalog number, revision, quantity, destination and nameplate photo. Identification details will be checked before quotation.
