Product Overview

The 990-04-70-01-05 converts the vibration signal from a matched 3300 NSv proximity system into a two-wire 4-20 mA loop signal. This exact suffix selects a 0-4 mil pp measurement span, 7.0 m system length, 35 mm DIN-rail mounting clips and a combined approval option. It is suited to machinery packages that use conventional loop-powered monitoring and control inputs. Before ordering, confirm the existing transmitter label, loop voltage and resistance, NSv probe and extension-cable length, mounting method, approval requirement and desired full-scale range.

Loop accuracy
+/-1.5% of full scale
Frequency response
5 Hz to 6 kHz, +0/-3 dB
Not OK signal
Less than 3.6 mA
Current limiting
23 mA typical

Signal and Loop Engineering

The transmitter accepts +12 to +35 Vdc. Maximum loop resistance is 1000 ohms at 35 Vdc. The buffered Prox Out has a 1.4 mm linear range and a typical scale factor of 7.87 mV per micrometre (200 mV per mil). A minimum 9.5 mm target is specified for the proximity system. Verify receiving-card scaling and loop burden before commissioning.

Applications

  • Centrifugal air-compressor packages
  • Small pumps, motors and fans
  • OEM machinery protection interfaces
  • 4-20 mA vibration trending
  • Maintenance replacement of an exact 990 suffix

Environment and Mounting

Transmitter operating temperature is -35 to +85 C; storage temperature is -52 to +100 C. The system supports 100% condensing humidity when non-submerged and connectors are protected. Install on the specified 35 mm DIN rail, maintain accessible terminals, keep probe wiring separate from noisy power conductors and follow the applicable approval installation requirements.

Compatibility and Revision Notice

Confirm the complete 990-04-70-01-05 suffix, full-scale range, 7.0 m matched NSv system, loop supply, load resistance, DIN-rail format, approval marking and receiving-card scaling. Please contact us to confirm the exact revision, firmware version, condition and availability before ordering.

Inspection, Shipping and Warranty

Condition is established in the written quotation. Inspection can cover label and suffix verification, enclosure and terminal review, serial-number recording and an applicable loop-output check. Worldwide shipping can be arranged with protected terminals and export packaging. Warranty is 12 months under written quotation terms.

FAQ

What measurement range does 990-04-70-01-05 use?

The 04 range code specifies 0-4 mils pp, equivalent to 0-100 micrometres pp.

What NSv system length is required?

The 70 code specifies a 7.0 m matched probe-and-extension-cable system.

Can the transmitter connect directly to a 4-20 mA input?

It provides a two-wire 4-20 mA output, but the loop supply, receiving-card scaling and resistance must be checked.

Which approvals are included in option 05?

The option covers CSA Division 2, ATEX Zone 0, ATEX Zone 2 and ABS maritime approval; confirm the delivered marking.

Can you provide label photos before shipment?

Yes. Ask for available product and label photos when requesting the quotation.
