Robust Eddy Current Measurement System

N/A The eddyNCDT 3005 is a new, powerful eddy current measurement system for fast, high precision displacement measurements. The system comprises a compact controller, a sensor and an integrated cable and is factory-calibrated for ferromagnetic and non-ferromagnetic materials.

As sensor and controller are temperature-compensated, high measurement accuracies can be achieved even in fluctuating temperatures. The sensors are designed for ambient temperatures up to max. +125 ºC but can optionally be custom engineered for temperatures from -30 ºC to +180 ºC. The measurement system is pressure-resistant up to 10 bar and so is ideally suited to machine integration.

Ideal for Integration into Plant and Machinery

N/A The eddyNCDT 3005 provides ease of use and high measurement accuracy, offering an outstanding price/performance ratio. Therefore, the sensor is ideally suited to OEM integration and mechanical engineering applications. Particularly where pressure, dirt, oil and high temperatures are present, the eddyNCDT 3005 is suitable. Where high volume orders are required, customer-specific designs can be tailored to suit individual requirements.

Multi-Channel Operation without Mutual Interference

N/A If two or more systems operate next to one another, there is no need for synchronization. For operating several systems, a new frequency separation is provided, which enables to operate these systems in parallel without influencing one another. Tuning via synchronization cable is not necessary.
