990 Approved Bulkhead-Mount Vibration Transmitter

A 5 mil full-scale, 7.0 m bulkhead vibration transmitter with the multi-agency approval option.

Product Overview

This approved 990 transmitter is intended for machinery packages that need a simple 4–20 mA shaft-vibration signal and a 7.0 m NSv transducer path. The bulkhead arrangement keeps the electronics accessible at an enclosure or panel while the probe remains at the machine.

Its suffix combines a 0–5 mil peak-to-peak range, 7.0 m system length, bulkhead mounting screws and the multi-approval option. Those approvals must still be matched to the markings on the supplied unit and to the site’s barriers, wiring method and area-classification drawing.

For a useful handover, commission both outputs: prove the control-system loop across the full scale and capture the Prox Out bias and waveform at a known machine state. The two records make later fault-finding much faster than a loop value alone.

Selection, Installation & Diagnostics

Selection

  • Match the 7 m NSv chain, 5 mil range and bulkhead hardware.
  • Confirm code 05 markings against the approved area and marine documentation.

Installation

  • Follow the certified wiring and barrier arrangement for the specific site.
  • Leave safe access to terminals and the diagnostic output after bulkhead mounting.

Diagnostics

  • Check loop current and Prox Out together when the control-system trend shifts.
  • Do not bypass approved wiring methods while testing a suspected fault.

Frequently Asked Questions

Which approval details must match the site design before 990-05-70-02-05 is used in a classified area?

The supplied-unit approval markings, area classification, barrier schedule, wiring method and grounding arrangement should all agree with the approved installation design.

How should the 7.0 m NSv signal chain be assembled for 990-05-70-02-05?

The probe lead and extension-cable lengths should add up to 7.0 m so the installed chain matches the transmitter calibration.

What enclosure access should remain available after 990-05-70-02-05 is bulkhead mounted?

The installation should leave safe access to the terminals and diagnostic point while providing suitable cable-entry space, grounding and wire bend clearance.

How is the 5 mil range of 990-05-70-02-05 represented at the DCS?

The normal mapping is 4 mA at zero vibration and 20 mA at 5 mil peak-to-peak; verify the site configuration and units during the loop test.

What does a healthy loop test still fail to prove about 990-05-70-02-05?

It does not prove probe gap, target condition, waveform quality or correct system length. Check Prox Out and the complete NSv chain as well.

When readings from 990-05-70-02-05 become intermittent, what should be investigated first?

Inspect supply headroom, bulkhead terminals, shield and ground treatment, probe gap, connectors and cable damage before changing the transmitter or DCS scaling.
