Product Overview

991-06-70-03-05 is a two-wire loop-powered Bently Nevada 991 thrust transmitter for axial displacement measurements with a matched 3300 NSv probe and extension cable.

The complete code specifies a 0.6-0-0.6 mm full-scale range, 7.0 m system length, DIN clips and bulkhead screws, plus CSA Division 2, ATEX Zone 0 and Zone 2, and ABS maritime approvals.

It provides a proportional 4-20 mA loop signal, a buffered ProxOut signal and an immediate Not OK current indication below 3.6 mA.

Applications & Features

Loop-powered output

A two-wire 4-20 mA signal transmits thrust position to a control or monitoring system.

Buffered ProxOut

A buffered proximity signal supports setup and diagnostic measurements.

Rapid Not OK response

The loop current drops below 3.6 mA within 100 microseconds when the transducer system is Not OK.

Flexible mounting

The selected 03 option includes both 35 mm DIN clips and bulkhead mounting screws.

Connections

Power and signal	Two-wire +12 to +35 Vdc loop with 4-20 mA output
Probe input	Matched 3300 NSv probe and extension cable, 7.0 m total system length
Buffered output	ProxOut connection for setup and diagnostics
Mounting hardware	DIN clips and bulkhead screws supplied by option 03
Loop loading	Maximum 1000 ohm at 35 Vdc; calculate allowable resistance for the actual supply voltage

Installation

01 - Verify the complete code

Match 991-06-70-03-05 on the label, quotation, packaging and order record.

02 - Install the transmitter

Use the supplied DIN clips or bulkhead screws and observe the published mounting dimensions.

03 - Connect the transducer

Use the selected 7.0 m matched NSv probe and extension-cable system.

04 - Wire the loop

Provide +12 to +35 Vdc and keep total loop resistance within the published limit.

05 - Commission the range

Verify the 0.6-0-0.6 mm scale, 4-20 mA output, ProxOut response and Not OK indication.

Maritime approval

Selected suffix includes ABS maritime approval.

FAQ

Q1. How can the exact quoted 991-06-70-03-05 be verified?

Match the complete code on the label and documents. Confirm 0.6-0-0.6 mm range, 7.0 m system, DIN clips, bulkhead screws and approval suffix 05.

Q2. How can New, Used or Refurbished condition be distinguished?

Request date-marked photos of the label, housing, terminal block, DIN clips, screws, seals and packaging. Look for terminal marks, corrosion, opened fasteners or replaced labels.

Q3. How should supplier legality and reliability be checked?

Verify the legal entity, registered address, payment beneficiary and traceable contact. The written offer must name Bently Nevada and complete model 991-06-70-03-05.

Q4. Which specifications must engineering confirm before purchase?

Confirm the 0.6-0-0.6 mm range, 7.0 m NSv system, +12 to +35 Vdc supply, loop resistance, 4-20 mA input compatibility, mounting method and required approvals.

Q5. What physical evidence should be requested before payment?

Ask for dated photos showing the complete label, terminal area, housing, DIN clips, bulkhead hardware and approval markings, plus a powered loop test showing normal 4-20 mA response.

Q6. Can another 991 suffix replace 991-06-70-03-05?

Not automatically. Suffixes change full-scale range, system length, mounting hardware and approvals. Engineering must approve all four code positions before substitution.
