RD 018 – Proximity Transducer

The RD 018 proximity transducer is designed to deliver accurate displacement measurement for rotating machinery. Using the eddy-current measuring principle, this sensor measures relative movement without contact, making it ideal for shaft vibration and displacement monitoring in industrial settings.

High Precision Proximity Transducer for Industrial Displacement Sensing

RD 018 has a measuring range of approximately 8 mm, and is built with an M24×1.5 thread. Cable outlet is axial or radial depending on installation needs. Because it operates via eddy currents it offers rapid response, robustness in harsh environments, and interchangeability among probes with matching cable lengths. It is suited for use with evaluation electronics like the TWW 101 M1, TWW 201, or TWW 201-8 for displacement or vibration monitoring.

Key Benefits

• Contactless displacement or vibration monitoring, reducing mechanical wear

• Wide measuring range of up to 8 mm for flexibility in monitoring gap or shaft movement

• Mounting flexibility: thread M24×1.5 with choice of axial or radial cable exit

• Compatibility with established evaluation electronics for easy integration

Application Areas

Useful wherever precise gap, shaft displacement, or relative movement need to be tracked, especially in:

• Industrial turbines and generators monitoring shaft vibration or displacement

• Rotating machinery in power plants or manufacturing plants

• Pumps and compressors where shaft misalignment or wear must be detected early

• Gearboxes or bearing housings where precise displacement measurement improves maintenance planning
