EPRO MMS3210/010-000 Dual Channel Axial Displacement Transmitter
MMS3210/010-000 belongs to Emerson/Epro MMS3000 rotating machinery monitoring system, which is a dual channel shaft displacement/axial position transmitter. MMS3210/010-000 is equipped with PR642x series eddy current probes, which use non-contact measurement methods to collect signals such as axial displacement, shaft position, and differential expansion of the shaft, and complete signal conditioning, filtering, and threshold judgment; Output 4-20mA analog signal connected to DCS/PLC, with built-in alarm relay. When the axial movement of the rotor exceeds the safety threshold, an alarm or interlock signal is output to protect the thrust bearing, prevent rotor rubbing and major equipment damage. It is the core state monitoring and protection unit of high-speed rotating units such as steam turbines and compressors.
Main function:
- Dual channel independent acquisition, two channel parameters can be configured separately, and two axis displacement measurement points can be collected simultaneously.
- Suitable for EPRO full series PR642X eddy current probes, non-contact measurement, no mechanical wear, suitable for high-speed rotor monitoring.
- Built in sensor fault diagnosis, real-time detection of probe wire breakage and short circuit faults, avoiding false alarms.
- Supports two independent 4-20mA analog outputs, which can be directly connected to the DCS system for real-time transmission of displacement measurement values.
- Each channel is equipped with two-level alarm relays, and the warning and danger trip thresholds can be freely set, supporting interlocking protection.
- Equipped with redundant power supply interfaces, it can provide dual 24VDC power supply, improving the operational reliability of key units such as power plants.
- The aluminum alloy shell has an IP65 protection level and can be directly installed near the unit body without the need to be placed in the control cabinet.
- Equipped with a voltage test output port, the probe signal can be detected on site without dismantling the wiring, making debugging and maintenance convenient.
- Meets the API670 standard for rotating machinery protection and is suitable for critical equipment safety protection circuits.
- Anti vibration and wide temperature design, capable of withstanding harsh working conditions such as high temperature, vibration, and humidity in power plants and petrochemical sites.
