MTN/EP480

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

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
