990 Bulkhead-Mount Vibration Transmitter

A 5 mil full-scale vibration transmitter for a 7.0 m NSv system with bulkhead mounting and no agency approval option.

Product Overview

This 990 configuration turns shaft-relative vibration into a two-wire 4–20 mA signal for a PLC or DCS. Its 7.0 m NSv system length is useful when the probe-to-transmitter route exceeds the common 5 m arrangement, while the bulkhead hardware supports enclosure-wall mounting.

The model is scaled for 0–5 mil peak-to-peak vibration, code 70 sets the probe-and-extension-cable total to 7.0 m, and code 02 selects bulkhead mounting screws. The final code 00 means no agency approval option is specified.

The 4–20 mA output is well suited to trending and general protection, but commissioning should still include probe gap and Prox Out checks. That extra step prevents a wiring or mechanical problem from being hidden behind a plausible-looking loop current.

Selection, Installation & Diagnostics

Selection

  • Confirm that the existing NSv probe and cable total 7.0 m.
  • Check enclosure drilling and service access for the bulkhead mount.

Installation

  • Verify loop voltage at the transmitter after accounting for the receiving-device load.
  • Protect the Prox Out connection and follow the non-isolated test-equipment guidance.

Diagnostics

  • Use a below-3.6 mA reading as a fault clue rather than a negative vibration value.
  • Compare loop current, bias and waveform before replacing the transmitter.

Frequently Asked Questions

How should the 7.0 m NSv signal path be confirmed for 990-05-70-02-00?

Add the probe lead and extension-cable lengths and confirm that their documented total is 7.0 m. System length is part of the calibrated signal chain, not spare cable allowance.

What enclosure details should be checked before drilling for 990-05-70-02-00?

Confirm the mounting template, internal clearance, wire bend space, grounding plan and access to the terminals and diagnostic point.

Is 990-05-70-02-00 suitable for a hazardous area when code 00 specifies no approval option?

Code 00 means no agency approval option is specified. This configuration is appropriate only where the project classification and local requirements permit it.

Why can a stable loop from 990-05-70-02-00 still show the wrong vibration at the DCS?

Check that 4–20 mA is scaled to 0–5 mil peak-to-peak and that engineering units, range and channel type match at every receiving system.

If current from 990-05-70-02-00 falls below 3.6 mA, where should diagnosis begin?

Measure supply at the transmitter, inspect loop continuity, verify probe gap and NSv connectors, then use Prox Out to narrow the fault.

Which system-chain details should be recorded after commissioning 990-05-70-02-00?

Record probe model and lead length, extension-cable length, transmitter model, final gap, loop load and a stable running baseline.
