The measurement process of the LevelCheck 510M is based on the newest
microwave technology, whereby the transmitter sends out a microwave
signal which is analysed by the opposite receiver. Material which builds
up within this field attenuates its signal effect, and this is then
converted into a switching procedure. The measurement is contactless. The sensitivity, signal attenuation and signal hysteresis of the
microwave barrier can easily be set continuously and precisely using the
bar graph display. This allows for a variable determination of the
switching point or a switching process for different process parameters.
