Vibro-Meter GSI127 244-127-000-017-A2-B01 Mechanical Vibration Monitor Module

Product Description

Vibro-Meter GSI127, Part No. 244-127-000-017-A2-B01, is a galvanic separation unit of Meggitt Vibro-Meter S3960 series. It is a signal isolation and conditioning module for rotating machinery vibration monitoring chains. It supplies power and galvanic isolation for vibration sensors and signal conditioners, with 4kV RMS reinforced isolation between sensor side and monitoring side to eliminate ground loop interference and realize long-distance high-precision transmission of high-frequency vibration signals. It supports intrinsically safe explosion-proof applications, compatible with piezoelectric accelerometers, IEPE sensors and eddy current probe preamplifiers. DIN rail mounted, widely used in vibration protection loops of turbines and compressors. Suitable for SIL safety-related systems and supplied as spare parts for industrial rotating machinery monitoring systems.

Application

Used for vibration monitoring and protection systems of steam turbines, gas turbines, centrifugal compressors, hydro turbines and large fans. Widely applied in power plants, petrochemical, oil & gas and offshore platforms. Serving as isolation safety unit in vibration measurement chain, it supplies power for field sensors, isolates ground potential difference and suppress common-mode interference to ensure stable long-distance transmission of vibration and shaft displacement signals. Used for maintenance replacement of legacy Vibro-Meter online vibration monitoring systems.
