Wilkerson Instrument Co.

What Wilkerson Instrument Co. does

Wilkerson Instrument Co., Inc. is a Lakeland, Florida-based privately held manufacturer of industrial signal conditioning and process control instrumentation, founded in 1983 and operating with 11–50 employees. The company designs and sells plug-in (Mighty Module), DIN-rail (DIN Mod and DR Series), and two-wire (TW3, SR2000, SF1302) signal conditioners that convert sensor inputs — DC, AC, RTD, thermocouple, frequency, potentiometer, and strain gauge — into standardized 4-20 mA current loop outputs compatible with PLCs, RTUs, and SCADA systems. It also produces water/wastewater-specific solutions (LM1000 level monitor, LS1000 submersible pressure sensor, DR6305 three-phase phase monitor, DR1920 duplex lift station backup pump controller) and continues to offer legacy Motorola MOSCAD I/O interface products for ACE3600 RTUs. UL/cUL recognition and explosion-proof / NEMA 4 options are available for hazardous and outdoor installations.

The company's go-to-market combines a toll-free phone line (800-234-1343), an online shopping cart at wici.com, and a listed distributor network targeting municipal water/wastewater operators and general industrial process control buyers, primarily in the Southeast US. Unit pricing is publicly listed and ranges from $29 for entry-level two-wire transmitters to $1,100 for the LS1000 submersible sensor. The company is led by Cecil Johnson as President and COO. Wilkerson has publicly disclosed that it is seeking a buyer and that, absent a sale, it will permanently close on August 28, 2026; effective July 1, 2026 all orders are prepaid via credit card or ACH transfer, and it has discontinued third-party Citel and Turbines Inc product lines as part of the wind-down.

Core offering

Wilkerson Instrument Co. designs, manufactures, and sells industrial signal conditioning and process control instrumentation, including plug-in and DIN-Rail mounted signal conditioners, two-wire (4-20mA) transmitters, loop-powered process indicators, and water/wastewater products such as level monitors, submersible pressure sensors, phase monitors, and duplex pump controllers. The company also distributes wireless data acquisition solutions and Motorola MOSCAD I/O interface products for integration with industrial PLC, RTU, and SCADA systems.

Product overview

Wilkerson Instrument Co. offers a portfolio of industrial signal conditioning and process control instrumentation products organized into three main form factors: Mighty Module Series (plug-in modules), DIN Mod Series and DR Series (DIN-Rail mounted devices). These products convert, condition, isolate, and transmit industrial sensor signals (temperature via RTD/thermocouple, process variables via DC, strain gauge, frequency, potentiometer, and AC inputs) into standardized 4-20 mA current loop outputs. The company also provides a line of Water/Wastewater products including the DR6305 Phase Monitor, DR1920 Pump Controller, LM1000 Level Monitor, and LS1000 Pressure Sensor designed for lift stations and municipal water applications. Process indicators (LP400/LP420) provide local display of 4-20 mA signals. The product line specializes in two-wire transmitter technology and wireless data acquisition solutions for industrial automation.
