Liquid Level Sensors

Auburn Liquid Level Sensor
Auburn liquid level control electrodes are used in control systems that rely on the electrical conductivity of fluids. These products are ideal for controlling liquids and moisture levels in foods, dairy, drug, and chemical processing. Additional applications include liquid level control in steam boilers, water heaters, supply tanks, and sewage disposal systems.

Three series of Auburn liquid level control electrodes are offered to meet specific application requirements. The WCT series with Teflon insulation, the WCC series with ceramic insulation, and the WCC-KH series with Teflon protected ceramic and Kovar center wire. All metal components, unless stated otherwise are 303 and 304 stainless steel.

Alumina Insulation WCC Series

Metal parts are 300 series non-magnetic stainless steel. Teflon insulation and seals are for applications up to 1,000 psi at 70Degrees F. and 400 deg F at 1 atmosphere, and will maintain their insulating properties when subjected to many corressive chemicals.

Observation Ports

Auburn Observation Ports
Auburn observation ports remain leak proof under high pressure and at high temperature because of unitized one-piece construction. Cico-weld eliminates the need for an organic gasket that can deteriorate under adverse pressure and temperature conditions. Pyrex viewing glass prevents cracking under rapidly changing operating temperatures.
