Capacitive measurement controller with integrated Profinet interface

Precision sensor manufacturer Micro-Epsilon has further expanded its capaNCDT 62xx range of multi-channel capacitive controllers with the addition of the DT6240 controller with integrated Profinet interface.

This means users benefit from real-time measurement data without any time delays, as well as reduced installation and wiring effort. Capacitive systems from Micro-Epsilon offer some of the highest precision measurements available to industry.

The new DT6240-PROFINET controller enables direct integration of the full capacitive sensor performance directly into PLCs and other control systems via Profinet without requiring additional separate interface modules. The controller is configured and parameterised directly via Industrial Ethernet.

As well as an attractive price-performance ratio, the DT6240-PROFINET controller has a modular design that allows it to be expanded at any time by up to four measuring channels. The controller is compatible with all sensors and cables from the capaNCDT series of capacitive displacement sensors from Micro-Epsilon.

Like the DT6220 and DT6230 capacitive controllers, the DT6240-PROFINET also uses the DL6220 and DL6230 demodulators for operation. The DT6240-PROFINET can be used as a benchtop unit, wall-mounted unit or DIN rail-mounted via an adapter.

Capacitive controller range

The capaNCDT 62xx range of controllers from Micro-Epsilon is an entirely modular, multi-channel measuring system. Based on the basic single-channel system, the user can autonomously expand the system by up to four measuring channels. The range now comprises of four basic controller models:

• DT6220 – Ethernet, 5 kHz
• DT6230 – Ethernet/EtherCAT + external synchronisation, 5 kHz
• DT6222 – Ethernet, 20kHz
• DT6240 – Profinet, 5 kHz

Depending on user requirements, the controller can be combined and expanded with different demodulators. Each demodulator can have its own set of characteristics for extended cable length and/or adjustment of the connected sensors measurement range to either increase or decrease the range by factor 2.

In terms of modularity, interfaces and precision, the DT62xx range is the most innovative capacitive measuring system available on the market. Customers come from a range of industries including semiconductors, laboratories and research, automation and medical engineering, with applications ranging from thickness measurement to oscillation measurement, coordinate measurement, evenness and brake test stands.
