Selection Guide

Use the following criteria to select the correct thrust transmitter for your application:

Step 1 – Confirm chassis: Verify your 3500 system chassis model and available slot type.
Step 2 – Check MOD number: MOD:284318-01 indicates a specific hardware revision. Confirm your system accepts this revision.
Step 3 – Output range: Confirm 4–20 mA output is compatible with your DCS/PLC analog input card.
Step 4 – Probe compatibility: Ensure the proximity probe and extension cable are matched to this transmitter’s input impedance.
Step 5 – Safety rating: If installed in a SIL loop, confirm the SIL rating of the replacement matches the original.
Step 6 – Contact Konmask: Send us your existing part number, MOD number, and system model for a verified cross-reference.

Replacement & Compatibility FAQ

Q: Can I replace 991-01-XX-01-05 with a 990-series transmitter?: A: The 990 and 991 series share similar proximity measurement principles but differ in output conditioning and chassis compatibility. A direct swap requires engineering verification. Contact us for a cross-reference analysis.
Q: What does the “XX” in the part number mean?: A: The “XX” is a wildcard placeholder representing a specific sub-variant code (e.g., gap voltage range or cable length option). Always confirm the exact two-digit code from your existing unit’s label before ordering.
Q: Is MOD:284318-01 the latest hardware revision?: A: MOD numbers indicate hardware revisions managed by Bently Nevada. Contact our team or the OEM to confirm whether a newer MOD revision is backward compatible with your installation.
Q: Can this transmitter work with non-Bently Nevada probes?: A: It is designed for Bently Nevada proximity probe systems. Using third-party probes may affect measurement accuracy and void warranty. Engineering review is required for any non-OEM probe substitution.
Q: Do you provide a warranty on replacement units?: A: Yes. We offer a standard 90-day warranty on all units shipped. Extended warranty and on-site support can be arranged for large orders or critical applications.
