Large turbine generators
The CIDE arrangement is used on large steam-turbine generators to measure rotor-to-casing growth where differential or rotor expansion must be tracked.

Product facts
Product Description
Bently Nevada 330879-03-00 is the two-clamp option in the 3300 XL 50 mm sliding probe bracket and clamp family. The set supplies one right-exit and one left-exit clamp so both probe cables can leave from the same side of a complementary-input differential-expansion arrangement.
The 00 field in Bently Nevada 330879-03-00 specifies no DE mounting bracket, leaving the order as the dual clamp set rather than a complete sliding bracket assembly. The clamp geometry holds the 50 mm probes while the separately selected machine-side bracket provides positioning and travel.
Bently Nevada 330879-03-00 uses T6061-T6 aluminum clamp/bracket construction within the family. The clamp faces, securing fasteners and cable exits must be aligned as a pair so the two transducers can observe the common differential-expansion target without cable interference.

Complementary-input DE projects
Product Applications: Steam-Turbine Differential Expansion
Bently Nevada 330879-03-00 is the paired clamp set used when two 3300 XL 50 mm probes are arranged on opposite sides of a differential-expansion collar.
Extended DE range
Opposing probes on the collar support complementary-input measurement when the required total range is approximately 28 to 56 mm, beyond the single 27.9 mm probe range.
Paired cable routing
One left-exit and one right-exit clamp place both probe cables on the same side of the CIDE bracket so the measurement opening remains clear.
Three-step installation
Installation & Integration: CIDE Sliding Bracket
Because Bently Nevada 330879-03-00 contains the clamp pair only, installation requires a separately selected short or long CIDE bracket and its sliding base assembly.
01
1. Install the bracket base
Select the short 131030-01 or long 131031-01 CIDE bracket for the turbine geometry and fasten its base plate to the inner turbine case near the differential-expansion collar.
02
2. Fit clamps and probes
Attach the left- and right-exit clamps to the sliding carriage, install the two 50 mm probes and keep both cable exits on the intended side of the bracket.
03
3. Gap, verify and secure
Loosen the carriage bolts, slide the probes through the required range to set and verify the gaps, then tighten the bolts and install the safety wire; a spindle-micrometer verification kit can provide the travel reference.
Practical selection and use
Common Questions
What exactly is included in Bently Nevada 330879-03-00?
Bently Nevada 330879-03-00 includes two probe clamps: one right exit and one left exit. The 00 field means no DE mounting bracket is included with the clamp set.
Why are opposite-hand clamps used in Bently Nevada 330879-03-00?
The opposite hands in Bently Nevada 330879-03-00 let both 50 mm probe cables exit from the same side of the CIDE bracket. This avoids crossing the cables through the measurement opening.
Which bracket must be selected for Bently Nevada 330879-03-00?
Choose the separate short or long complementary-input differential-expansion bracket for Bently Nevada 330879-03-00 based on the machine geometry. The clamp-only order does not define that bracket length.
How should the paired probes be aligned in Bently Nevada 330879-03-00?
With Bently Nevada 330879-03-00, align both clamps to the common target and preserve the required probe spacing. Set the sliding bracket position before securing its bolts and safety wire.
What material is used for the bracket family around Bently Nevada 330879-03-00?
The clamp and associated bracket family for Bently Nevada 330879-03-00 uses T6061-T6 aluminum. Inspect contact faces and fasteners separately from the stainless-steel probe cases.
What should be checked if one cable route is obstructed on Bently Nevada 330879-03-00?
For Bently Nevada 330879-03-00, confirm that the left- and right-exit clamps have not been swapped or rotated against the intended cable side. The two cables should leave the CIDE bracket together without a sharp bend.
