FIELDS OF APPLICATION
· Vehicle climate control system with alternative drives
· Heat pump
DESCRIPTION
The CCT pressure temperature sensor is installed in climate control systems, particularly
in vehicles with alternative drives, and heat pumps. The specially developed thermo-
receptors permit a fast response time in flowing media and guarantee high temperature
accuracy. The design excels due to its compact size and minimal weight, which makes
it easy to integrate and ideal for lightweight systems. The specific evaluation electronics
make the pressure and temperature signal available via a digital single wire interface
(LIN). High quantities can be realised at an affordable price thanks to fully automated
production.
