Temperature conditioning systems for water-cooled pressure sensors / 2621G

The new systems of Type 2621G are used for temperature conditioning of water-cooled pressure sensors and ensure constant thermal conditions at the sensor – irrespective of the varying operating conditions of the combustion engine. It ensures stable and reproducible measurements avoiding overheating of the sensor or excessive steam condensation on the sensor diaphragm when the engine is stopped. The temperature conditioning system consists of a refrigera- ting set, water hoses for inlet, outlet and manifold. The sensor tubes are connected to the distributor through quick couplings. The temperature conditioning system has an automatic monitor of temperature, pressure, flow and level. The signal output of the automatic monitor can be used for controlling an electrical alarm device. The Kistler temperature conditioning system ensures that the sensors are supplied with the optimal water quantity. Note that experience has shown that the heat flow of a cooled engine sensor is about 200...400 W, depending on the application and the engine
