Product Description
Bently Nevada 3701/44 (Part No.:177896-01) is the ADAPT Aeroderivative Monitor module, a high-end machinery condition monitoring unit from Baker Hughes. It is specially designed for aeroderivative gas turbines and their driven equipment. It supports multi-sensor signal acquisition, order tracking filters and combustion dynamic pressure pulsation measurement for machine protection and online diagnostics. It can be skid-mounted close to machinery to reduce sensor wiring length. It works with System 1 diagnostic software and BNMC configuration software, serving as a critical spare part for gas turbines and high-speed rotating machinery.
