Eddy Current Probes

Monitran eddy current probes are resistant to contamination from oil, dirt, dust and water and are used on a wide range of applications including:

Pumps
Turbines
DC gap machine tools
Gauges
Plain metal bearings
Centrifuges

As standard, each eddy current probe in our range will be supplied with 1 metre of integral cable; coaxial, ETFE insulation with an internal copper braid and stainless steel over braid. Extension cables (with the same characteristics) are available up to 8 metres in length.

MTN/EPHD080

MTN/EPHD80 This heavy-duty eddy current probe system is designed for the greatest protection from harsh industrial conditions. Rugged IP65 cast aluminum driver housing with integral probe. Stainless steel probe sleeve tailored to exact insertion depth required and the probe can be exchanged without recalibration. Unit can be based on any driver type highlighted in this guide. Particularly suited to thrust or vibration measurements on pumps and turbines.

Probe Diameter: 5mm
Operating Gap: 0 - 2mm
Insertion Length: As required
Protection: IP65
Entry: M20

MTN/EPHD080

Extension Cable

Eddy current probes are supplied with 1m of integral cable which can be extended to 9m (by the addition of up to 8m of extension cable). However, long cables will often give installation problems as they need to be rotated during the gap set-up process; in which case screw-on extension cables are recommended. However, once a system has been manufactured and calibrated with an extended cable it can only be exchanged or renewed with one of equal length and the system will require recalibration.

Type: Coaxial, ETFE insultaion, copper braid
Overbraid: Stainless steel
Maximum Length: 8 metres
Connectors: SMC to match probe and driver
