Industrial WCC-1138 Liquid Level Sensor

The Auburn WCC-1138 Liquid Level Sensor is a replaceable liquid-level electrode used with Auburn control systems to detect liquid presence in tanks and process vessels. It features a 3/8-18 NPT threaded connection and measures 3.32 inches long, enabling installation through standard ports in steam boilers, water heaters, and chemical-processing tanks. In distributor listings, WCC-1138 appears under the Auburn part number CS13096 and is described as discontinued by the manufacturer, with related variants such as WCC-1138L and E5-WCC-1138L appearing in nearby Auburn product lines. This electrode/probe acts as the sensing element within Auburn’s level-detection ecosystem and is described in some catalogs as a liquid level electrode or probe, or as a sensor accessory within a probe-holder assembly. Retailers and service part catalogs also identify WCC-1138 as the Auburn liquid level control electrode and note its predecessor status in the Auburn lineup. Despite its discontinued status, the WCC-1138 remains a reference point for legacy equipment where Auburn-level sensing is specified, and distributors may offer compatible substitutes or refurbished stock to support ongoing installations.
