LUMENITE

LUMENITE is a manufacturer of liquid level control and sensing instrumentation, with a product line that includes conductivity-based level controllers, capacitive level transmitters, resistance temperature detectors (RTDs), and sanitary temperature transmitters. The company's catalog covers both sensing elements (probes and transmitters) and control units (relay-based controllers with SPDT or DPDT contact forms), enabling end-to-end level and temperature monitoring in industrial processes. LUMENITE products are designed for applications requiring reliable detection of conductive or non-conductive liquids, as well as temperature measurement in hygienic or corrosive environments. Typical build standards include stainless steel probe construction (304 or 316 series), NPT, Tri-Clamp, and bevel seat process connections, and enclosures rated for DIN rail or octal socket mounting. Probe lengths range from 12 inches to custom dimensions, with process connection sizes from 1/2 inch to 2 inches. Controllers operate on AC supply voltages (24V, 110V, 240V) and provide relay outputs with LCD or no-display options. The MLXT-4220 series capacitive transmitters offer accuracy better than 0.1% with 4-20 mA two-wire output, suitable for continuous level measurement in tanks. The LSTT-4220 series sanitary transmitters cover temperature ranges from 0°F to 350°F with RTD sensing elements and Tri-Clamp connections. 3G Electric stocks over 100 SKUs of LUMENITE products, including probes, controllers, transmitters, and accessories, with datasheets and logistics support for global shipment. The range supports plant engineers and maintenance managers in specifying level and temperature instrumentation for water treatment, food and beverage processing, chemical storage, and HVAC systems. All products are sourced directly from LUMENITE or authorized channels, ensuring traceability and compliance with applicable industrial standards.

Frequently asked questions

Common questions about LUMENITE from 3G Electric.

What types of liquid level probes does LUMENITE offer?

LUMENITE offers liquid level probes in several connection styles: NPT (e.g., PHS41AST12" with 1 1/2" NPT), Tri-Clamp (e.g., T-2DCFT-1-1/2 with 1 1/2" Tri-Clamp), and bevel seat (e.g., T-DAFT2 with 2" bevel seat). Probes are constructed from stainless steel and are available in single or dual probe configurations. Probe lengths vary, with common options including 12 inches. These probes are designed for use with LUMENITE conductivity level controllers.

What is the difference between LUMENITE conductivity level controllers and capacitive level transmitters?

LUMENITE conductivity level controllers (e.g., WFLTV-DM-6011, WFLTV-SM-201(24)) use the electrical conductivity of the liquid to detect level and provide relay outputs for pump control or alarms. They require probes that contact the liquid. Capacitive level transmitters (e.g., MLXT-4220-P-3/4-24") measure changes in capacitance caused by the liquid's dielectric constant, offering continuous level output (4-20 mA) with accuracy better than 0.1%. Capacitive sensors can be used with non-conductive liquids and do not require direct contact with the liquid.

Can LUMENITE sanitary temperature transmitters be used in food processing applications?

Yes, LUMENITE sanitary temperature transmitters (e.g., LSTT-4220-C2-350F) feature a 2-inch Tri-Clamp connection and a 12-inch probe, making them suitable for hygienic applications such as food and beverage processing. They use an RTD sensing element and provide a 4-20 mA output over a temperature range of 0°F to 350°F. The stainless steel construction and sanitary connection comply with common industry requirements for clean-in-place (CIP) environments.

What mounting options are available for LUMENITE liquid level controllers?

LUMENITE liquid level controllers are available in DIN rail-mount (e.g., WFLTV-DM-6011) and octal socket-mount (e.g., WFLTV-SM-201(24)) configurations. DIN rail models are designed for snap-on mounting on standard 35 mm DIN rails, while octal socket models plug into an 8-pin octal base. Both types feature relay outputs with SPDT contact forms and operate on AC voltages (24V or 110V).

Does LUMENITE offer a combination liquid level and temperature controller?

Yes, LUMENITE offers combo controllers such as the LASD-401(24), which integrates liquid level and temperature control in a single unit. It features a 100 Ohm RTD temperature sensor, relay output with (2) SPDT contacts, LCD display, and snap-track mounting. It operates on 24V AC and is suitable for applications requiring both level and temperature monitoring in a compact package.

What is the accuracy of LUMENITE capacitive level transmitters?

LUMENITE capacitive level transmitters, such as the MLXT-4220-P-3/4-24", specify accuracy better than 0.1%. These transmitters use a rod probe made of 304 stainless steel and provide a 4-20 mA two-wire output. They are designed for continuous level measurement in tanks and vessels, suitable for both conductive and non-conductive liquids.
