GN 848 Float Switch for Level Monitoring

Float switches GN 848 can be used to monitor fluid levels by activating an electrical switching contact as soon as a defined filling level is exceeded or falls below a defined mark. The desired level at which the switching point is to be reached is determined by the length of the float rod. With the float removed, this rod can be shortened; a scale for oil or water facilitates determining the exact length. The top end of the float rod features a magnet which activates a reed contact when the appropriate position is reached, irrespective of the medium to be monitored.Depending on the installation position of the magnet in the float rod, either the make contact (NO) or the break contact (NC) may be operated. When delivered, the magnet is set for operating the make contact (NO).
