Core Signal Processing Function
The EPRO MMS6410 is a high-performance, dual-channel measuring amplifier for precise signal conditioning. This unit processes signals from inductive displacement sensors and differential transformers. It provides accurate measurements of displacement, position, and velocity for machinery monitoring. Consequently, it is a critical component in predictive maintenance and protection systems for rotating equipment.
Independent and Protected Channel Design
Each of the two channels features differential, galvanically isolated inputs for superior noise immunity. The inputs are also open-circuit and short-circuit proof for enhanced reliability in harsh environments. The MMS6410 provides a separate, buffered power supply for each connected sensor. Furthermore, its measuring frequency range of 0 to 100 Hz covers both slow trends and dynamic events.
Detailed Technical Specifications
This amplifier offers versatile configuration with common logical binary control inputs for both channels. It supports a key pulse input for per-revolution referencing in speed or phase analysis. The following table details its comprehensive electrical and performance parameters.
