Functional Features:
Dual-channel, 3U-sized, 1-slot plug-in modules cut cabinet space requirements in half compared to traditional four-channel 6U cards
API 670-compliant, hot-swappable modules
Pre/post buffered and proportional outputs, 0/4-20 mA outputs, 0 – 10V outputs
Self-test features include monitoring hardware, power inputs, hardware temperature, sensors and cables
Used to connect a displacement sensor and a seismic or piezoelectric sensor
or piezoelectric sensor so that the combined output is an absolute value of the axis relative to free space
For use with displacement transducers 6422. 6423. 6424. and 6425 as well as actuators CON 011/91. 021/91. 041/91. and case-mounted piezoelectric velocity sensors
The Shaft Absolute Vibration Monitor is designed for high reliability in the plant’s most critical rotating machinery.
This 1-slot monitor is used with other AMS 6500 monitors to form a complete API 670 machinery protection monitor.
Applications include steam, gas, compressor and hydraulic turbine machinery.
The primary function of the absolute shaft vibration monitoring module is to accurately monitor absolute shaft vibration, to
The main function of the shaft absolute vibration monitoring module is to accurately monitor shaft absolute vibration and reliably protect the machinery by comparing the vibration parameters to alarm setpoints and actuating alarms and relays.
The shaft absolute sensor system consists of a relative displacement sensor and a vibration sensor mounted in the same housing.
The displacement sensor is a non-contact sensor that measures shaft position and movement relative to the housing, the
while the vibration sensor mounted in the housing is used to measure the absolute position of the housing relative to free space.
The two sensors are phase compensated for different units and mathematically subtracted to obtain the absolute displacement of the shaft relative to free space.
Absolute shaft vibration is an important measurement used for prediction and protection monitoring on all sleeve bearing machines.
Absolute shaft vibration should be selected when the bearing box and rotor masses are closely matched, as the bearing box may move significantly during machine operation.
The AMS 6500 is an integral part of PlantWeb® and AMS software.
PlantWeb provides comprehensive machine health in conjunction with the Ovation® and DeltaV™ process control systems.
AMS software provides maintenance personnel with advanced predictive and performance diagnostic tools to accurately determine machine failures at an early stage.
