Capacitive sensors for use down to -230° C

EGE capacitive sensors for use down to -230°C reliably detect deep-frozen liquid gases or granulates for cryogenic grinding, for example. The sensors are based on the proven capacitive principle. The measuring element of the sensor designed as a cylindrical capacitor. The medium to be detected functions as dielectric. The medium in touch with the sensor generates a capacity change. This is converted into a switching signal or an analogue 4...20 mA output signal. This applies both to conductive and on-conductive media. The sensors reliably record super-cooled liquid gases or granulate, for example for cryogenic milling. With their compact design the sensors of this series are well suited for installation in tight spaces.
