Emerson Epro|MMS3120/022-000|Dual-Channel Bearing Vibration Transmitter
EPRO MMS3120/022-000 Dual-Channel Bearing Vibration Transmitter
Description
The EPRO MMS3120/022-000 is a dual-channel bearing vibration transmitter for measuring absolute vibration using seismic sensors, compliant with VDI 2056 and API 670 standards.
Features
- Dual inputs for PR 9268 series seismic sensors
- Two 0/4–20 mA current outputs with system ground
- Five configurable function outputs (opto-coupler standard)
- Integrated sensor and module supervision
- Redundant 24 V DC power supply
- RS-232 interface; optional RS-485 or PROFIBUS DP
- Direct machine mounting, IP65-rated housing
Technical Specifications
- Compatible sensors: PR 9268/20, /30, /60, /70
- Measuring modes: Vibration velocity (VRMS), amplitude (S₀₋ₚ, Sₚ₋ₚ), MAX(x,y)
- Frequency range: High-pass 5/10/15 Hz; Low-pass 50–1500 Hz
- Current output: 0/4–20 mA or 20–4/0 mA, max. load 500 Ω
- Buffered signal output: ±5.0 V, error ±2.5%
- Linearity error: ≤0.2% (electronics only); <2.2% (with sensor)
- Output stability: <0.08%/10 K
- Long-term drift: ≤1% of full scale
- Power supply: 18–31.2 V DC, max. consumption 6 W
- Operating temperature: –20°C to +65°C (mounting surface ≤65°C)
- Protection: IP65, EMC per EN 55011 and EN 61326
