A temperature sensor of type KTY11−5 from Infineon is used in the DFME. The manu−
facturer's characteristic curves and technical data can be found in the Internet.

BiSS interface measuring system
The BiSS interface is a 2−wire interface for interference−immune sensor connection.
In contrast to the SSI interface, data transmission is bidirectional, i.e. data can
also be written to the sensor, for example for parameterisation.
Data transmission takes place over a pulse wire and a data wire operated by the
sensor for serial transmission. Writing data to the slave is done via pulse−width mo
dulation of the clock in accordance with the BiSS B mode" protocol specification
http://www.biss−ic.de/files/BiSS_b3ds.pdf; a directional switch of the data trans
mission line does not take place. Pulse and data are transmitted in RS485 technology,
that is, a signal is not inverted and sent inverted and output at the receiver as a differ
