EPRO MMS3110/010-000 Dual-channel Shaft Vibration Monitoring Transmitter

EPRO MMS3110/010-000 Dual-channel Shaft Vibration Monitoring Transmitter (MMS3000 Series)
I. Product Basic Information
Brand: EPRO (Germany, now acquired by Schneider’s Prokon for industrial rotating machinery condition monitoring, a benchmark brand in this field)
Product Series: MMS3000 Online Mechanical Monitoring System
Full Model: MMS3110/010-000
Equipment Type: Dual-channel shaft vibration transmitter, specifically designed to handle eddy current probe signals, used for radial vibration monitoring of turbine, compressor, fan, pump, etc., compliant with API670 and VDI2059 international rotating machinery monitoring standards.
/010: Hardware configuration code, representing the basic standard version: built-in preamplifier, two channels of vibration input, two channels of 4-20mA analog output, photoelectric isolation switch quantity alarm; -000: basic factory configuration, no fieldbus expansion.
Companion Sensors
Must be paired with EPRO original PR6422 / PR6423 / PR6424 / PR6425 series eddy current displacement probes, Lemo aviation connectors for direct insertion modules, modules with preamplifiers, no additional external preamplifier units required.
Compared with your previous Bently 330180 preamplifier solution: This EPRO set is an integrated transmitter design, with on-site signal conversion and output of 4-20mA.

Core Technical Parameters
Measurement Channels: Dual-channel independent X/Y direction shaft vibration measurement, can output two vibration values separately, or output the maximum value Smax according to API670 rules
Frequency Response: 1Hz~1500Hz, covering the frequency and harmonic vibration monitoring requirements of turbine units
Measurement Accuracy: Linear error at 25℃ is less than 0.25%FS, excellent temperature drift and time drift indicators, suitable for long-term online monitoring
Analog Output: 2 isolated 4-20mA current outputs, can be directly connected to AB ControlLogix analog module; 4mA corresponds to the lower limit of the range, 20mA corresponds to the upper limit of the range; when the sensor is disconnected or short-circuited, output 0mA for PLC to identify the fault
Switching Output: 5 isolated alarm outputs, can be set as warning Alert, danger Danger, sensor fault OK signals, can be directly connected to SIS/Triconex ETS trip circuits
Power Supply: Supports redundant 24VDC direct current power supply, single power supply failure does not interrupt monitoring, commonly used in power plants
Communication and Configuration: Built-in RS232 interface, using dedicated software or onboard dip switch settings for range and alarm threshold; optional RS485/Profibus expansion (this model / 010-000 does not have bus expansion)
Self-Diagnosis Function: Real-time detection of probe disconnection, short circuit, abnormal signal, once a fault occurs, immediately cut off normal measurement output and trigger fault alarm
