- Key Products/Technologies
- Spinning Rotor Gauge (SRG) Technology: A direct physical measurement principle determining pressure by measuring the deceleration rate of a magnetically levitated, freely rotating stainless steel ball [1, 4]. This method calculates pressure through momentum transfer from gas molecule collisions [1, 4]. It ensures non-contact measurement without any interference to the vacuum system [7, 14].Spinning Rotor Gauge (SRG) Technology: A direct physical measurement principle determining pressure by measuring the deceleration rate of a magnetically levitated, freely rotating stainless steel ball [1, 4].

- DosiTorr SRG Transducer: An autonomously operating process manometer based on SRG technology [2, 4]. It offers a measurement range from 10 mbar to 5x10^-7 mbar, with a high accuracy of 1% in the range of 0.1 to 1x10^-6 mbar [2, 4]. Key features include long-term stability with less than 1.5% drift per year and a stainless-steel sensor insensitive to corrosion and deposition [2]. Magnetic shielding and an integrated temperature sensor provide a stable measurement environment [2].DosiTorr SRG Transducer: An autonomously operating process manometer based on SRG technology [2, 4].
