Product Description
The Epro MMS3120/022-100 is a dual-channel vibration transmitter that converts the signals from electrodynamic vibration transducers into independent output signals proportional to vibration velocity or amplitude. It features self-diagnostic functions, redundant power supply, and configurable settings using DIP switches and jumpers.
It is suitable for use in large-scale industrial systems with programmable logic controllers (PLCs) and host computers, commonly found in power plants, refineries, and chemical plants. The transmitter provides limit supervision and ensures continuous monitoring of machine health.
Applications
The MMS3120/022-100 is primarily used for the monitoring and protection of rotating machinery, including:
- Turbomachinery (Steam and gas turbines)
- Compressors
- Fans & Blowers
- Gearboxes
- Pumps
It is especially suited for industries that require continuous machine monitoring, such as power generation, oil & gas, chemical processing, and heavy manufacturing.
Product Advantages
- Dual-Channel Measurement – Monitors two independent vibration signals simultaneously.
- Highly Configurable – DIP switches allow flexible measurement settings.
- Industrial-Grade Durability – IP65-rated aluminium housing for harsh environments.
- Self-Test & Diagnostics – Detects faults in the sensor and electronic module.
- High Accuracy & Stability – Linearity error of 0.25%, stable over time and temperature.
- Redundant Power Supply – Ensures reliability in industrial environments.
- Seamless Integration – Works with Epro PR 9268 vibration sensors and other standard electrodynamic transducers.
- Alarm & Limit Supervision – Configurable alerts for preventive maintenance.
