Below is a comprehensive overview of Lumenite® Control Technology, Inc.—a U.S.-based manufacturer (est. 1934) of precision instrumentation for level, temperature, pressure, conductivity, timing, and pasteurization control.

🏭 Company Overview

Founded in 1934 and proudly Made in the U.S.A., Lumenite® designs, engineers, and manufactures rugged control instruments for sanitary, industrial, and hazardous environments ebay.com+14lumenite.com+14dasenic.com+14lumenite.com.

1. Conductivity Level Controls

Ideal for detecting liquid level using conductivity principles, available in multiple configurations:

• Octal Socket Mount – single relay for simple on/off or fill/empty control

• DIN-Rail Modules

  • Model 201: 1 relay

  • 401: 2 relays

  • 601: 3 relays

• 3″ Snap‑Track – compact form factor for panel installations

• Industrialeveline™ – customizable standalone solutions

These UL‑353 certified controllers are intrinsically safe and suitable for explosive atmospheres, boiler systems, and sanitary/industrial environments lumenite.com+1digikey.com+1lumenite.com+5lumenite.com+5digikey.com+5.

2. Capacitance Level Transmitters (4220 Series)

The 4220 Series RF Capacitance Transmitters deliver continuous analog outputs (4–20 mA, voltage) proportional to material level in any shaped tank. They work with conductive and non‑conductive liquids, plus moist granular solids raptorsupplies.com.

3. Conductive & Non‑Conductive Level Probes

Lumenite offers a wide range of single and dual-level stainless steel probes (e.g., PHST38QUN) compatible with their transmitters and suitable for sanitary configurations sigmasurplus.com+14dasenic.com+14digikey.com+14.

4. Temperature Transmitters & Thermowells

Sanitary/industrial RTD and thermocouple temperature transmitters convert temperature readings into 4–20 mA output. They come in rugged enclosures for plant and washdown settings raptorsupplies.com.

5. Pressure Transmitters & Gauges

Continuous 4–20 mA pressure transmitters with tri‑clamp sanitary fittings, and analog/digital gauges ideal for fluid pressure monitoring in hygienic processes .

6. Digital Timing Controls & Universal Meters

• Digital Timing Controls: Weekly/yearly programmable timers with astronomical functions and Li-ion backup—used for lighting, generators, etc. Accessories and PC integration available lumenite.com+2lumenite.com+2lumenite.com+2.

• LDM-4-LSP-2 Universal Process Meter: 4-digit display, input compatibility with current/voltage/RTD/TC, Modbus® RTU, and USB/RS‑232/RS‑485 communications .

7. H.T.S.T. Pasteurization Test Systems

Portable MTC‑4000 pasteurization test timer with 0.01 s accuracy, used for milk, juice, beer. Includes tri‑clamp probes, saline injector, USB interface, and rugged carry case lumenite.com.

8. Boiler Probes

High-integrity brazed probes (e.g., HP‑PHST38Q) used for steam/water detection in boilers, compatible with Clark‑Reliance® standards. Rated to 3,000 psi at 1200 °F, hydro‑tested and gas‑tight lumenite.com+1digikey.com+1.
