Introduction
1.Function
This is a compact signal conditioning transmitter integrated with proximitor circuit.plcva.com
- Receive displacement signal from Bently 3300 NSv non-contact eddy current proximity probe.
- Convert shaft peak-to-peak vibration displacement into standard 4–20mA analog current signal.
- Two-wire loop-powered design, powered via the same 4–20mA signal cable.
- Built-in Not OK / Signal Defeat circuit: automatically outputs low current (<3.6mA) when probe failure or cable disconnection occurs, to avoid false high vibration alarms.
- Provide auxiliary dynamic PROX OUT and gap voltage output for on-site diagnosis and waveform inspection.
- Equipped with zero & span trimming potentiometers for on-site calibration; test input pin supports quick function verification.
- Potted sealed construction, suitable for high humidity and condensing industrial environments.

2. Application
Main Application
Designed for OEM and industrial rotating machinery monitoring: Centrifugal air compressors, small pumps, fans, motors and other medium-speed rotating equipment.plcva.com
It is widely adopted in equipment control systems (DCS / PLC) where simple vibration monitoring is required, instead of large rack-based monitoring systems.plcva.com
Purpose
- Real-time shaft vibration measurement: continuously monitor rotor relative vibration of rotating machines.
- Standardized signal transmission: send 4–20mA vibration value to DCS/PLC for display, trend recording and threshold alarm.
- Machinery protection: trigger alarm or interlock shutdown when vibration exceeds preset limit, prevent rotor rubbing and equipment damage.
- Fault diagnosis: reserved dynamic gap voltage and vibration signal interface for troubleshooting during commissioning or maintenance.
- Predictive maintenance: track vibration trend to discover early rotor faults such as unbalance and misalignment.
