I. Model Disassembly

7200: 7200 series platform

EIP: Eccentricity Input Panel (Panel with eccentricity input)

P: Panel/Pointer (with pointer display)

Full name: 7200-EIPP (Part number: 72992-09)

II. Core Functions and Parameters

Purpose: Monitor rotor eccentricity (bending), determine thermal bending, dynamic and static friction, for use in steam turbines.

Channels: 1 channel of electrical eddy current probe input (commonly 8mm probe + 18745 preamplifier).

Range: 0–2 mils (0–50.8 μm), high-resolution small range.

Display: Panel analog pointer display + alarm LED, local direct reading of eccentricity value.

Output:

4–20mA analog quantity (into DCS)

Alarm / Hazard Relay Dry Contact

Power supply: -24VDC (backplane of 7200 rack)

Status: Original factory completely discontinued, only second-hand / refurbished spare parts circulated. 

III. Differences from 7200‑RVR/RVDP‑R

7200‑EIPP: ** eccentric (bent) ** monitoring, small range, high resolution, for turbine applications.

7200‑RVR/RVDP‑R: Radial vibration monitoring, large range (0–15 mils), for general rotating machinery.

IV. Upgrade Replacement (Corresponding to 3500 Series)

Direct replacement card: 3500/45 (7204574‑01) — General-purpose eccentric / axial displacement card, digital, with communication.

Sensor: Original 7200 probe + preamplifier can be directly used (electrical compatibility 3500).

V. Summary

7200‑EIPP = 72992‑09: This is the 7200 series analog eccentric monitoring card from Bently, with a pointer display, used for turbine rotor thermal bending protection; it has been deeply discontinued, spare parts for old units can be used, and new projects should be uniformly upgraded to 3500/45.
