30000-00-23-36-02 is a factory pre-calibrated flush-type eddy-current proximity probe from Bently Nevada 30000 series, designed and produced per API670 industry standard for turbomachinery supervisory instrumentation and safety protection systems. Assembled with factory-certified matched extension cable and compatible proximitor transducer, the probe forms a complete closed-loop non-contact displacement measurement circuit following eddy-current induction principle. It converts real-time clearance fluctuations between flush sensing end face and metallic rotor surface into stable linear DC voltage signals to continuously monitor radial shaft vibration, axial thrust displacement and Keyphasor rotational speed. The product is extensively used on critical high-speed rotating equipment including steam turbines, centrifugal compressors, turbo-generator sets, boiler feedwater pumps and industrial blowers in thermal power, petrochemical refining and metallurgical industries. Each finished probe undergoes full-loop capacitance matching test, wiring continuity inspection, alternating high-low temperature cyclic aging test and connector sealing durability verification before delivery, ensuring stable measurement accuracy under harsh industrial environments with drastic temperature variation, heavy lubricant mist and complex electromagnetic interference. All analog output signals are transmitted to Bently 3500 monitoring rack, on-site DCS or PLC system to trigger pre-alarm and emergency trip interlock, preventing severe mechanical failure induced by excessive rotor offset and over-limit vibration.
