Product Description
-
The 177989-01 PAV Module is an input module for the 3701/44 ADAPT Aeroderivative Monitor.
-
It accepts inputs from proximity probes (“Proximitor”), accelerometers, and Velomitor velocity sensors.
-
It provides six dynamic sensor-channels plus one dedicated Keyphasor / speed input channel.
-
Supports both high-frequency acceleration measurements and velocity measurements with configurable bandwidths and signal conditioning.
-
Designed for protection and condition monitoring on aeroderivative gas turbines and associated rotating equipment.
