Bently Nevada 200350-00-00-00 100 mV/g Industrial Accelerometer
A Bently Nevada piezoelectric accelerometer for bearing-housing and machine-casing vibration measurement.
Product Profile
200350-00-00-00 is intended for industrial casing-vibration measurement with compatible constant-current signal conditioning. Mounting quality and input-excitation polarity directly affect the validity of the measurement.
Its complete order code defines the supplied stud, sensitivity tolerance and approval selection, so each field should remain visible in procurement records.

System Role
- Welded hermetic stainless-steel housing for industrial machinery environments.
- Shear-mode ceramic sensing element for casing-vibration measurement.
- Top-exit two-pin connector supports the documented moisture-resistant cable family.
- Broad measurement bandwidth supports general machinery condition monitoring.
Compatibility
- Use an input that provides the documented constant-current excitation and accepts the sensor bias voltage.
- Match the 1/4-28 mounting interface and two-pin connector cable.
- Do not substitute a 200355 when tolerance, bandwidth, physical size or approvals are part of the channel design.
Applications
- Bearing-housing vibration monitoring on pumps, motors and rotating machinery.
- Portable or permanently wired condition-monitoring measurements with compatible input electronics.
- Replacement of an identical mounted sensor where the existing stud and cable system are documented.
FAQ
What distinguishes 200350-00-00-00 from other 200350 order codes?
Its suffix selects the standard 1/4-28 stud, the documented ±20% sensitivity tolerance and no agency approval option.
Can 200350-00-00-00 use a negative-excitation monitoring input?
No. Bently Nevada specifically warns not to use the 200350 sensor with negative excitation voltage.
What should be checked before replacing 200350-00-00-00?
Confirm mounting surface, stud thread, cable connector, constant-current excitation, bias monitoring and channel scaling.
Is a magnetic base suitable for permanent 200350-00-00-00 protection service?
Use the mounting method defined by the measurement plan; temporary magnetic mounting can change response and should not be assumed equivalent to the specified stud installation.
What installation issue most affects 200350-00-00-00 signal quality?
Poor mounting on the bearing housing or casing can reduce amplitude and frequency response or introduce false signals.
Which approval status applies to 200350-00-00-00?
The final 00 code means no approvals; select and document the appropriate approved variant where the area classification requires it.
