DATA SHEET Economical level switch The B/W 6012/6013 conductivity switches offer an economical solution to measurement of most conductive liquids. Multiple switch points The B/W conductivity switch offers single point or up to 13 switch points mounted in one electrode holder. Various Electrodes Available Both rigid and wire suspended electrodes are available in a wide variety of materials and temperature/pressure specifications. Suitable for many Applications Applicable to conductive liquids for high or low level indication, pump control, and stop fill on storage vessels. A simple device that utilizes the conductive properties common to aqueous liquids to provide reliable point level measurement. The electrodes are suspended in the vessel and when the material being measured makes contact with the electrodes, a circuit is completed which actuates a B/W relay. Conductivity switches can be connected to B/W relay modules to provide control or alarm contacts. Relays are available for general purpose and with intrinsically safe outputs for hazardous areas. B/W Conductivity electrodes and holders are available in a variety of materials for use in many different process liquids. 6012 Electrode Holders Specifications Material of Construction: 316SS, Cast Iron, PVC, Brass Number of switch points: Up to 13 Operating Temperature: Up to 450°F Operating Pressure: Up to 2000 psi 6013 Electrodes Specifications Material of Construction: 316 SS, Brass (other materials available) Maximum Length of electrodes: Rigid up to 10 feet / Wire suspended up to 200 feet (longer lengths available) Operating Temperature: Up to 450 Degrees F Operating Pressure: Up to 2000 psi
