990 Vibration TransmitterPrice:
AskA 0-5 mil peak-to-peak vibration transmitter for a 7.0 m NSv system, with bulkhead mounting and CSA Division 2 approval option.
This 990 transmitter provides a simple route from a 3300 NSv proximity chain to a plant 4-20 mA vibration channel. Its buffered Prox Out connection gives maintenance a direct view of the proximity signal during setup and troubleshooting. For this loop, 990-05-70-02-01 combines the specified vibration range, system length and mounting method.
The configured range is 0-5 mil peak-to-peak, with a 7.0 m total probe-and-extension-cable path. Bulkhead screws suit panel mounting, and approval code 01 identifies the CSA Division 2 option. Those four option fields distinguish 990-05-70-02-01 from other 990 transmitter configurations.
Before energizing the loop, confirm power, mounting clearance, coaxial connections and the DCS scale. Gap the probe within range, prove the 4 mA and 20 mA points, and keep a machine-state baseline for future comparisons. Saving the 990-05-70-02-01 baseline with the machine state makes future loop diagnosis more decisive.
Add the NSv probe lead and the correct extension cable so the electrical total is 7.0 m. Use the component part numbers for this decision because routed distance alone does not identify calibrated length.
Allow room for the mounting hole, rear terminals, grounding, coaxial bend radius and access to zero, span, test and Prox Out. The bulkhead face can fit while the enclosure remains too shallow for service access.
Map 4 mA to zero vibration and 20 mA to 5 mil peak-to-peak, then verify at least one intermediate point with the approved loop-test method. This prevents a healthy transmitter from appearing incorrect in the DCS.
Set the probe inside the published 0.5 to 1.75 mm gap range and check that the output remains above the Not OK threshold. A marginal gap can drive the loop below 3.6 mA even when field wiring is intact.
The supplied unit should carry the CSA Division 2 marking that matches the project classification. The bulkhead installation method and local enclosure requirements still determine whether the completed loop is acceptable.
Compare the buffered Prox Out signal with the 4-20 mA current. A credible Prox Out signal with an incorrect DCS value points toward bulkhead wiring or scaling, while an abnormal Prox Out signal keeps attention on the 7.0 m probe chain.
