Burkert – Type 8412 RTD Temperature Sensor with CANopen Interface

RTD temperature sensor with CANopen interface

Resistance thermometers are the preferred choice for measuring the temperature of liquids and gases. The design offers reliable tightness under negative and positive pressure.

The measuring insert is equipped with a Pt1000 temperature sensor according to DIN EN 60751, Class A. The measured temperature value is digitised, linearised and made available via the CANopen digital communication interface (CAN slave) for further processing.

Instead of an analogue output, this device offers the ­CANopen digital interface. This allows bidirectional data transfer, e.g. with a CAN/Ethernet gateway or directly to a PLC that is equipped with a CAN interface. CAN devices can also be connected to the Bürkert büS digital communication interface. A driver used for data exchange and settings of the 8412 is integrated in the Bürkert PC tool Communicator.

Several useful auxiliary functions have been implemented through the DS 404 device profile.
