Key Features & Engineering Advantages
Parallel Dynamic Sampling:Unlike multiplexed systems, the 2155/40-01 samples all 24 dynamic channels simultaneously. This is critical for cross-channel phase analysis, which is essential for identifying complex faults like shaft cracks or hydrodynamic instability.
High-Bandwidth Capability:With a DC to 30 kHz range, the processor captures everything from low-speed structural movements to high-frequency gear mesh and aero-derivative turbine signatures.
Unified Process & Dynamic Data:By integrating 24 process inputs (temperature, pressure, flow) alongside vibration data, the TDiSecure allows operators to see how process conditions directly impact mechanical vibration levels.
Secure Infrastructure:As the "Secure" name implies, this processor is designed with robust internal architecture to safeguard critical machine data during transmission over plant networks.
Flexible Signal Conditioning:The process input groups are highly versatile, supporting multiple industrial standards including 4-20 mA and various voltage ranges (0-5V, 0-10V, etc.), making it a "one-box" solution for diverse instrumentation.
