The 126623-01 is a 3500/44M Aeroderivative Gas Turbine Vibration Monitor for monitoring vibration in aeroderivative gas turbine applications. It supports multiple vibration measurement methods, interfaces with velocity transducers, Velomitor sensors, and accelerometers, and provides continuous machinery protection by monitoring critical vibration parameters and generating alarms when preset limits are exceeded.
Flexible Monitoring: Supports signal integration, 1X tracking, and band-pass filtering
Reliable Protection: Compares values with alarm setpoints for early warnings
High Availability: Supports TMR configurations and multimode operation
The 3500/44M Aeroderivative Gas Turbine Vibration Monitor is developed for aeroderivative gas turbines used in critical industrial processes. It is compatible with vibration monitoring systems for Rolls-Royce (RB211, Avon), GE (LM1600, LM2500, LM5000, LM6000), and United Technologies (GG3, G44, FT4, FT8) gas turbines.
The monitor accepts dual Keyphasor® inputs, allowing different tracking filters for each channel pair, and can be configured with multiple alarm parameter sets to automatically adapt to different operating modes. In Triple Modular Redundant (TMR) systems, three adjacent monitors operate with voting logic to improve system integrity and eliminate single-point failures, making the module well suited for high-reliability gas turbine monitoring and machinery protection systems.

Natural Gas Pipeline Transmission
Monitors casing vibration of aeroderivative gas turbine-driven centrifugal compressors in long-distance pipeline boosting stations.
Offshore Oil & Gas Platforms
Provides continuous protection for gas turbines driving main power generators and high-pressure water injection pumps on space-constrained offshore platforms.
Thermal Power Plants
Used for critical bearing vibration monitoring of gas turbines in peaking power plants or steam turbines in combined-cycle units.
Petrochemical & Oil Refineries
Protects large catalytic cracking air blowers driven by high-reliability gas turbines in heavy oil fcc or ethylene plants.
Mining & Ore Smelting
Monitors gas turbines in captive power plants of remote mining areas supplying electricity for heavy crushers and smelting furnaces.
Aviation Engine Test Cells
Receives and records vibration signals under high-speed rotation during performance testing of overhauled aeroderivative gas turbines or commercial aircraft engines.
When using the 126623-01 module, the rack power must be turned off during installation or removal to prevent hardware damage. External terminal and cable connections must remain securely tightened to withstand field vibrations, and the sensor cable shield must be grounded at a single end to eliminate electromagnetic interference.
Additionally, channel parameters must be synchronized via configuration software after installation to ensure monitoring accuracy.
