Now we offer direct replacements for the 3300 Series with added features of a Valox housing and BNC jacks for local data collection or analysis. Metrix proximity transducers are fully compliant with API 670 specifications and thrird party approvals are standard. The baseplate mounting holes are identical (requireing no field backplate drilling), DIN rail mounting is optional. Operating on the eddy current principle, these non-contact sensors sense shaft conditions with excellent resolution and stability. Motions as small as one micron (40 micro - inches) and up to 2.0 mm (80 mils) can be measured. A complete system consists of a probe, extension cable and solid state probe driver assembly. The 5533 Probe Driver has a convenient BNC signal jack for local analysis. The 10000 Series probes, cables and driver systems are certified for use in electrically hazardous areas. Others are pending by model number.
