General information

The VEGAPULS C 21, C 22, C 23 in ignition protection type encapsulation "m" are used for detec-
tion of the distance between medium surface and sensor by means of high frequency, electromag-
netic waves in the GHz range.
The electronics uses the running time of the signals reflected by the medium surface to calculate
the distance to the medium surface.
The VEGAPULS C 21, C 22, C 23 consist of an electronics housing, a process connection element
and a sensor or an antenna.
The VEGAPULS C 21, C 22, C 23 are suitable for applications in hazardous atmospheres of all
