Why must 990-10-70-03-00 use a different controller span from a 0-5 mil transmitter?

Its 0-10 mil peak-to-peak range is twice that span. A receiver left at 0-5 mil would under-report the same 4-20 mA fraction of full scale.

What is the nominal current at half scale for 990-10-70-03-00?

For the proportional 4-20 mA loop, half scale corresponds to 12 mA and 5 mils peak-to-peak. Confirm the actual calibrated endpoints during loop verification.

How should 990-10-70-03-00 be mounted when both clips and screws are supplied?

The 03 mounting option provides DIN clips and screws. Use the arrangement selected for the installation while keeping adjustment and wiring access clear.

Can shortening the probe cable preserve the calibration of 990-10-70-03-00?

No. Its 7.0 m electrical length depends on the matched probe and extension cable. Altering that chain changes the transducer relationship.

What is the typical current limit of 990-10-70-03-00?

The typical current limit is 23 mA. This overload behavior is distinct from the normal 20 mA full-scale measurement and the below-3.6 mA Not OK state.

How quickly does 990-10-70-03-00 recover after a corrected transducer fault?

Once the Not OK condition is removed, the signal is restored in approximately 2-3 seconds. Verify a stable recovery before restoring protection logic.

Which target conditions underlie the performance values for 990-10-70-03-00?

Unless specified otherwise, performance is based on a matched 3300 NSv probe and extension cable, an AISI 4140 steel target and +22 degrees Celsius.

Where are alarms generated when 990-10-70-03-00 is installed?

Alarm thresholds and protective logic belong to the receiving control system. Check its 0-10 mil scaling, fault-current handling and configured setpoints together.

Information

Overview Downloads Applications / Compatibility Product Precautions

Bently Nevada 990-10-70-03-00 brings radial shaft motion into the machinery controller through a powered current loop, while retaining a separate diagnostic connection for the probe signal.

Measurement span: 0-10 mils peak-to-peak
Transducer system: 7.0 m, compatible 3300 NSv probe and cable
Mounting: DIN clips and screws

The selected configuration combines a 0-10 mils peak-to-peak measurement span, a 7.0 m transducer system and din clips and screws. The integrated proximity conditioner accepts one compatible 3300 NSv probe with its matched extension cable; the probe lead and extension together establish the calibrated length.

The two-wire loop supplies power and transmits peak-to-peak shaft vibration amplitude as 4-20 mA. The receiving control system supplies the alarm and protection logic. Non-interacting zero and span adjustments support loop calibration, while the TEST input accepts a AC signal generator for controlled output checks.

The separate PROX OUT/COM and coaxial connection provide the dynamic and gap signal for diagnosis. This output is non-isolated and must be used with the specified test arrangement. Not OK/Signal Defeat drives the loop below 3.6 mA on a faulty transducer connection; power-up and fault recovery require approximately 2-3 seconds.

Controller platform reference: 3300 NSv transmitter system. Retain the calibrated chain and receiver scale.

The original technical excerpt for Bently Nevada 990-10-70-03-00 covers transmitter operation, electrical limits and diagnostic connections. The separate installation guide covers measurement scaling, loop burden, cable matching and controlled loop tests.

Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.

System and supply context: 990-10-70-03-00 connects a matched NSv probe and extension to a powered current-loop receiver. Probe, cable, test adapter and receiving control equipment are separate unless included in the quotation.

Application scope: Use the 0-10 mils peak-to-peak scale for shaft-vibration supervision of the assigned machine point. Protective alarm logic remains in the receiving system.

Machine-point signal conditioning
Convert one radial vibration measurement into a 4-20 mA input for the controller.
Calibrated loop renewal
Retain the 0-10 mils peak-to-peak receiver range and 7.0 m electrical chain when replacing the transmitter.
Probe-signal diagnosis
Observe the dynamic and gap signal with the specified diagnostic connection and instrument isolation.
Protection-loop verification
Use the TEST input with a AC signal generator to compare signal output and receiving indication.

Prepare Bently Nevada 990-10-70-03-00 for its configured installation using these checks.

Retain the measurement scale

Keep 0-10 mils peak-to-peak and its units in the receiver configuration.

Match the calibrated chain

The probe and extension together must equal 7.0 m.

Check loop burden

Provide the required terminal voltage after wiring and receiver losses.

Keep test grounding controlled

The diagnostic connection is non-isolated.

Recognize Not OK

Distinguish below-3.6 mA fault and startup states from valid measurements.

Restore protection deliberately

Remove test inputs and verify stable measurement before clearing the approved bypass.

Technical notes

Controller scaling: Retain the 0–10 mil peak-to-peak engineering span when testing loop current. A half-span test is meaningful only with the same range configured in the controller.

Fault recovery: Wait for the transducer fault-recovery interval before evaluating a restored signal. Confirm that the controller distinguishes a Not OK current from a valid low vibration value.
