TQ proximity probes
are eddy current transducers, for contactless measurements of relative vibration or axial displacement in turbines, alternators, turbo-compressors and centrifugal pumps. Our wide series of probes is API 670 compliant and available for high-pressure and watertight applications, with measuring ranges up to 12 mm.
