Conductivity level switches for water and wastewater applications
|On this page:||Downloads (PDF):|
Global Waters WL200 Conductivity Level Controllers provide reliable, cost effective, 2-point level control in applications where a mechanical switch would foul and an ultrasonic device could be inaccurate. The Conductivity Level Controller has no moving parts and may be used in water, wastewater and even slurries or other heavy bodied conductive liquids.
The WL200 Conductivity Level Controllers durable polypropylene sensing head with its integral junction box includes a standard 1 NPT fitting that allows for quick installation just about anywhere. The Conductivity Level Controller’s three 24 inch long 316 stainless steel electrodes are easily cut to length for accurate on/off or high/low point level settings.
The WL200 Conductivity Level Controller includes a sensitivity adjustment for reliable operation in a variety of conductive liquids. The Conductivity Level Controllers may be DIN rail or surface mounted and operate on standard 115 VAC current, which is stepped down to 12 volts at the electrodes. Only an extremely small amount of current is necessary for the unit to perform. As with any device, a properly installed and grounded system poses no electrical hazard.
The WL200 Conductivity Level Controller comes complete with sensing head, three 24 electrodes, controller with adjustable sensitivity, 8-pin socket, and 10 ft cable. For deeper applications use the WL200-EXT Conductivity Level Controller extension kit which includes three 24 inch probes, couplers and spacers.
