BENTLY 3500/44M 176449-03 is a high-performance multi-parameter monitoring module developed by Bently Nevada (now part of Baker Hughes, a GE company), belonging to the "M-Series" enhanced lineup of the 3500 Series Rotating Machinery Protection & Monitoring System. It is specifically engineered to simultaneously measure two critical safety parameters for large rotating equipment (e.g., steam turbines, gas turbines, and heavy-duty compressors): rotor thrust position (prevents rotor-stator rubs) and differential expansion (avoids thermal stress damage). Compared to the standard 3500/44 module, the "M-Series" variant adds advanced transient data capture and remote monitoring capabilities, making it ideal for safety-critical and complex industrial environments.
