991 Thrust Transmitter

A ±0.6 mm thrust transmitter for a 5.0 m 3300 NSv measurement chain, with DIN-rail mounting and no agency approval option.

Product Overview

Used for axial-position and thrust monitoring, this transmitter turns a matched 3300 NSv proximity signal into a 4-20 mA loop that a PLC or DCS can trend and alarm. Prox Out remains available for local signal-chain checks. In this application, 991-06-50-01-00 provides the defined axial-position range and loop interface.

The selected range is 0.6-0-0.6 mm, paired with a 5.0 m probe-plus-extension-cable path. DIN-rail clips support cabinet installation, and the 00 suffix means no agency approval option is specified. The combination of range, length and mounting options is what makes 991-06-50-01-00 the exact configuration.

Good thrust data begins with a documented mechanical reference. Confirm probe orientation and gap, establish zero at the known rotor position, prove the 4 mA and 20 mA points and retain the commissioning values for later diagnosis. Keeping 991-06-50-01-00 in the calibration record makes later thrust diagnosis much faster.

Selection, Installation & Diagnostics

Selection

  • Confirm the ±0.6 mm range and a 5.0 m total NSv chain from the loop documentation.
  • Verify DIN mounting, power budget and the absence of an agency approval option are acceptable.

Installation

  • Establish the rotor reference and correct direction before adjusting zero and span.
  • Keep shield and common wiring consistent with the cabinet grounding plan.

Diagnostics

  • Use Prox Out to check the analog sensing signal separately from the 4-20 mA channel.
  • Treat a current below 3.6 mA as a Not OK condition and inspect the whole sensing chain.

Frequently Asked Questions

Does the probe lead and extension cable used with 991-06-50-01-00 need to total exactly 5.0 m?

Yes. The probe lead plus the selected extension cable must equal the 5.0 m calibrated length used by this transmitter. Extra cable is not spare routing allowance and can change the proximity-system response.

How should the 0.6-0-0.6 mm span of 991-06-50-01-00 be centered on the rotor reference?

Set the rotor at the documented mechanical center, establish a valid probe gap and then adjust zero and span so the full axial travel fits the published 0.6-0-0.6 mm range without reversing direction.

Can the DIN-rail clips of 991-06-50-01-00 be reused without rechecking cabinet clearance?

The clips are part of the 35 mm DIN installation, but cabinet depth, terminal access and cable bend space still need to suit the actual panel. Reusing the rail does not prove the transmitter will remain accessible.

What does the 1,000 ohm maximum loop resistance of 991-06-50-01-00 mean at a 35 Vdc supply?

At 35 Vdc, the field cable and receiving input may total up to 1,000 ohms. A higher burden can prevent the loop from reaching its intended current even when the sensing chain is healthy.

How can Prox Out on 991-06-50-01-00 support zero-and-span setup before DCS handover?

Use Prox Out to observe the buffered proximity signal while zero and span are adjusted, then compare it with the 4-20 mA value. Agreement at the reference position exposes polarity or DCS scaling mistakes before handover.

Which commissioning values demonstrate that 991-06-50-01-00 is working with the intended 5.0 m chain?

Retain the 5.0 m component list, mechanical reference, gap voltage, Prox Out value, 4 mA and 20 mA points, thrust direction and machine condition. Together they prove both the calibrated chain and control-loop mapping.
