Piezo / Pirani, absolute pressure 1200 - 1.0e-4 mbar and relative pressure -1260 ... +940 mbar, metal sealed, DN16KF, Display

VSL53DL

The vacuum transducer VSL has been developed especially for loadlocks. The metal sealed gauge uses a multi sensor technology and combines two piezos with a Pirani sensor. Therefore, the vacuum transducer measures absolute pressure in the range of 1200 …1e-4 mbar as well as relative pressure in relation to the environment in the range of -1060 … +340 mbar.
The VSL is available in KF and CF variations and with different interfaces.
