JRS Float Level Switch


  • Parker float Level Switch.pngDetection balls and detection rods are completely enclosed and thus the products are not affected by pressure, vacuum, or gases
  • The lead switch is enclosed in a glass tube containing inert gas and thus the products operate safely in combustible gases
  • When the detection ball moves up and down due to buoyancy, the lead switches fixed to the upper/lower limit contact point positions are sensed.
  • Can be used for simultaneous control of water supply/drainage or alarms for water shortage/full water by additionally installing electrode type level switches (21F-G)
  • In particular, types with the control unit not built in the products can be used in regions with the risk of explosion or cases where the location of detection is far away from the location of control by installing the power supply part and the amplification part separately
  • Depending on connections, either N.C or N.O can be used or both can be used.
