Reed Chains

Reed Chains allow simple and effective continuous measuring of liquid levels.

Reed Switches and resistors are mounted onto a PCB. This PCB, now called Reed Chain, is inserted into a long stem and a matching Float is moving up and down the stem, according to the liquid level. With the Magnet inside the float switching the Reed Switches on and off the total resistance changes. This change in resistance gives easy, seamless and continuous level information.
