EPRO MMS 6410 MMS6410 Sistema de monitorização de máquinas

Overview:

• Part of the MMS 6000 machine monitoring system
• Designed for connecting inductive displacement sensors to measure absolute expansion, such as epro sensors PR 9350/.
• Signal frequency range up to 100 Hz
• Independent zero adjustment and zero shift for chosen measuring range
• Allows combining measuring results of both channels for calculations
• Sensor supply balanced to ground to reduce disturbances in industrial environments
• Equipped with RS 232 interface for configuration and reading measuring results
• RS 485 interface for connection to epro's MMS 6800 analysis and diagnosis system or host computers

Applications:

The MMS 6410 dual-channel measuring amplifier is suitable for measuring shaft displacements using inductive transducers in half- or full-bridge configurations or with differential transformers. Each measuring channel can operate independently or calculate sum or difference values of the measuring results from both channels. It can measure static and dynamic signals, including displacements, angles, forces, torsions, or other physical quantities measurable with inductive transducers. Displacement measurements are vital for constructing turbine protection systems and provide signals for analysis and diagnosis systems integrated into field bus systems and networks.
