Interface:

‑Harting heavy duty input connector for vibration sensor

‑Harting heavy duty output connector for 4-20mA & HART

‑LED indicator for power,alarm and fault status

Circuit feature:High precision signal acquisition circuit,built-in sensor cable break/short circuit self-diagnosis,shock and oil resistant,anti-electromagnetic interference for harsh industrial site.

Feature:EPRO MMS3120 dual channel field vibration transmitter,model /022-000 version. Support HART protocol for remote parameter configuration. Common faults:input circuit burnout,connector pin corrosion,internal sampling chip failure. Confirm sensor type and measuring range before replacement.

Diagnostic:Transmitter fault leads to bearing vibration signal loss,abnormal 4-20mA output,trigger TSI machinery protection alarm.

Built‑in function

MMS3120/022-000 collects bearing vibration data for rotating machinery condition monitoring,widely used for power plant TSI spare replacement.

Product Brief

MMS3120/022-000 belongs to EPRO field vibration transmitter family,wall mounted dual channel unit with HART communication. Verify sensor model and measuring range before ordering. Check sensor input,4-20mA output and HART communication function during commissioning. Widely applied for steam turbine,compressor,fan and pump condition monitoring. ESD anti‑static protection shall be followed during installation.
