A case-mounted seismic transducer that converts machine-casing acceleration into a differential voltage signal for the connected monitoring input.

Overview

Product Description

Bently Nevada 200350-00-00-00 is a general-purpose, case-mounted seismic accelerometer in the 200350/200355 accelerometer family. Installed on a bearing housing or machine casing, Bently Nevada 200350-00-00-00 converts vibration parallel to its sensitive axis into a differential voltage signal for the connected monitoring input.

Case mountedCeramic shearDifferential output

Inside the welded stainless-steel case, the ceramic shear element of Bently Nevada 200350-00-00-00 generates charge when the mounting surface accelerates. Integrated electronics convert that charge into the 100 mV/g nominal output, keeping the sensing element and signal conversion together in one hermetically sealed body.

Power and signal for Bently Nevada 200350-00-00-00 share pin A of the top-mounted two-pin connector, while pin B is ground. A positive 18 to 28 VDC, 2 to 20 mA constant-current supply operates the electronics, and the returned signal rides on an 8 to 12 VDC output bias.

Electrical path

Piezoelectric Signal Conversion

Bently Nevada 200350-00-00-00 combines the vibration-sensitive element and its conversion electronics in one case. The three stages below describe how mounting-surface acceleration reaches the monitoring input without treating a raw charge signal as the final output.

01 / SENSE

Ceramic shear response

Acceleration parallel to the sensitive axis loads the ceramic shear element in Bently Nevada 200350-00-00-00. The element produces charge in proportion to that mechanical motion.

02 / CONVERT

Integrated electronics

The internal circuit of Bently Nevada 200350-00-00-00 converts element charge into a differential voltage response. This conversion occurs inside the welded sensor case before the signal reaches the external cable.

03 / TRANSMIT

Constant-current interface

Through its two-pin connector, Bently Nevada 200350-00-00-00 receives positive constant-current excitation and returns the acceleration signal on the shared signal/power conductor relative to ground.

Mechanical fit

Mounting Geometry and Environmental Protection

The body dimensions, connector orientation and machine-side thread define how Bently Nevada 200350-00-00-00 fits its measurement point. The mounting interface transfers casing motion into the shear element, while the sealed housing keeps that mechanical path separate from the external electrical connection.

Machine-side interfaceBently Nevada 200350-00-00-00 uses a 1/4-28 female mounting hole and the option-00 0.5-inch stainless-steel stud with brass tip. Maximum mounting torque is 2 to 5 ft-lb.

Body and connector envelopeThe Bently Nevada 200350-00-00-00 body is 1.65 inches high with an 11/16-inch hex; its two-pin MIL-C-5015 connector exits from the top of the stainless-steel case.

Sealed operating rangeWelded hermetic construction gives Bently Nevada 200350-00-00-00 an IP68 enclosure rating, with a specified operating range from -54 to +121 °C and 5,000 g peak shock survivability.

Frequently Asked Questions

Q01

Can Bently Nevada 200350-00-00-00 be powered from a negative excitation supply?

No. Bently Nevada 200350-00-00-00 must not be used with negative excitation voltage. Use the specified positive 18 to 28 VDC constant-current supply and verify the 2 to 20 mA excitation path before connecting the monitoring input.

Q02

What mounting checks are required before installing Bently Nevada 200350-00-00-00?

Confirm that the machine surface provides the intended bearing-housing or casing measurement location, then check the 1/4-28 mounting interface and the 2 to 5 ft-lb torque limit. Bently Nevada 200350-00-00-00 includes the option-00 1/4-28 stainless-steel stud with a brass tip, so the mating hole and available 1.65-inch body height must suit that arrangement.

Q03

Which signal cable arrangement should be used with Bently Nevada 200350-00-00-00?

Use a standard or armored cable with the matching two-socket moisture-resistant female connector and monitor-end terminal lugs. The splash-proof cable is not recommended for Bently Nevada 200350-00-00-00; cable length must also remain within the electrical loading permitted by the installation.

Q04

How should an unexpectedly low or unstable reading from Bently Nevada 200350-00-00-00 be investigated?

Start at the mounting point: confirm that Bently Nevada 200350-00-00-00 is fixed to the bearing housing or machine casing at the intended location and that the surface and torque have not reduced the mechanical response. Then inspect the 2-pin connector, cable continuity, positive excitation and 8 to 12 VDC output bias before treating the accelerometer as the failed component.

Q05

Does the 00 approval suffix on Bently Nevada 200350-00-00-00 cover hazardous-area installation?

No. The final 00 in Bently Nevada 200350-00-00-00 identifies the no-approvals configuration. An installation that requires CSA, ATEX or IECEx approval must use the corresponding officially coded version and its stated entity parameters.

Q06

Can a 200355 accelerometer be installed as a direct replacement for Bently Nevada 200350-00-00-00?

Do not treat the two base models as automatically interchangeable. Bently Nevada 200350-00-00-00 has a +/-20% sensitivity tolerance, a 0.5 Hz lower frequency limit and its own noise, settling-time, impedance and physical values, while the 200355 values differ; the monitoring setup and mechanical fit must be checked against the exact model.
