About LUMENITE

Lumenite Control Technology is a U.S.-based manufacturer of liquid level and conductivity sensing instruments, with a product history that spans several decades in industrial and sanitary process control. The company's core product families include conductivity level controls, capacitive level sensors, float switches, and sanitary transmitters. These instruments are used to detect and control the level of conductive and non-conductive liquids, slurries, and interfaces in tanks, vessels, and pipelines. Lumenite devices are commonly specified in food and beverage, pharmaceutical, water treatment, chemical processing, and general industrial applications where reliable point-level or continuous-level measurement is required.

3G Electric supplies Lumenite level probes and related components to technical buyers worldwide. The current selection includes Tri-Clamp connection probes constructed from stainless steel, with process connection sizes of 1 1/2 inches and 2 inches, and probe lengths of 12 inches or adjustable from 12 to 24 inches. These probes are designed for point-level detection in sanitary process environments, where hygienic fittings and clean-in-place compatibility are necessary. The probes are available in configurations with two or three probes, allowing integration with Lumenite conductivity level controls for high, low, or intermediate level alarm and pump-control functions. Stainless steel construction provides resistance to corrosion and is suitable for contact with many process fluids.

Lumenite level controls and probes are engineered for direct installation into tank walls or vessel tops using standard process connections. The Tri-Clamp design allows for quick removal without special tools, which simplifies inspection and maintenance. Conductivity-based level sensing relies on the electrical conductivity of the liquid to complete a circuit between probe elements; this method is well established for detecting conductive liquids such as water-based solutions, acids, caustics, and many food products. Capacitive sensors, by contrast, are used for non-conductive materials or where non-contact measurement is preferred. Lumenite's product range covers both principles, giving plant engineers options based on the specific dielectric properties and conductivity of the process media.

For procurement specialists and maintenance managers, 3G Electric provides access to Lumenite part numbers including DCFT2, DCFT-1-1/2, T-2DCFT-1-1/2, 2DCFT-1-1/2, T-DCFT-1-1/2, 3DCFT2, 2DCFT2, and T-2DCFT2. These part numbers correspond to specific probe lengths, connection sizes, and probe counts. When selecting a replacement or new installation, the key specifications to match are process connection type and size, probe length, number of probe elements, and the electrical characteristics required by the level control unit. 3G Electric supports the Lumenite line by stocking these probes and providing quotation and order fulfillment for customers requiring single units or volume quantities. Technical documentation, including wiring and installation instructions, is available from Lumenite for each model.

Lumenite instruments are typically used in applications where sanitary design, chemical compatibility, and dependable point-level detection are priorities. The Tri-Clamp probes supplied by 3G Electric are constructed from stainless steel, which is a common material for food, dairy, beverage, and pharmaceutical process equipment. The probes can be used with Lumenite conductivity level controls to provide relay outputs for alarms, pumps, or valves. Because the sensing principle depends on the conductivity of the liquid, these probes are not suitable for non-conductive fluids such as oils or hydrocarbons unless used with a capacitive sensor instead. For those cases, Lumenite offers capacitive level sensors that detect the presence of material by changes in capacitance rather than conductivity.

3G Electric's role is to make Lumenite components available to a global customer base, with the ability to quote specific part numbers and configurations. The product data provided for each SKU includes manufacturer part number, probe length, process connection size, and material, allowing buyers to cross-reference against existing installations or design specifications. For applications requiring sanitary connections, the Tri-Clamp probes are available in 1 1/2-inch and 2-inch sizes, with fixed or adjustable probe lengths. These options cover a range of tank depths and mounting arrangements. When ordering, customers should confirm the compatibility of the probe material with the process fluid and the temperature and pressure ratings of the connection.
