รุ่น SKL
คุณลักษณะ
The SKL is a high-temperature pressure transducer with a cooling section. It can be used with liquid and gaseous media in temperatures of up to 180°C. These media are cooled down before measuring by means of cooling ribs that have been placed outside the sensor. This makes the SKL fit for use in heating systems, automotive equipment and in the chemical industry as well as for hydraulic and pneumatic applications involving higher temperatures.
The SKL has a stainless-steel chip with a semi-conductor thin film has been installed inside the SKL. The stainless-steel membrane is absolutely vacuumtight and extremely burst-proof. Its robust design guarantees to be highly reliable even in very rugged environments. Its modular design offers a multitude of signaling, threading and connecting options. Further0is available on request.
