# DwyerOmega

> DwyerOmega is a global manufacturer of sensors, instrumentation, and control products, formed when Michigan City's Dwyer Instruments (founded 1931) bought Connecticut's OMEGA Engineering (founded 1962) in 2022. Backed by private equity firm Arcline Investment Management, the combined company makes hundreds of thousands of devices that measure temperature, pressure, flow, level, humidity, gas, force, and more - the quiet instruments that keep HVAC systems, chemical plants, food lines, water utilities, and pharmaceutical facilities running within spec. Since the merger it has grown by acquisition, absorbing Process Sensing Technologies, Macurco, and Burns Engineering.

- **Founded:** 1931
- **Headquarters:** Michigan City, Indiana, United States
- **Founders:** Frank Dwyer (Founder, Dwyer Instruments (1931)), Betty Ruth Hollander (Founder, OMEGA Engineering (1962))
- **Team size:** ~980 employees
- **Products:** Differential Pressure Transmitters & Gauges, Temperature Sensors & Thermocouples, Flow & Level Instrumentation, Gas Detection & Indoor Air Quality, Data Acquisition & Data Loggers
- **Notable:** Dwyer Instruments has manufactured precision measurement instruments continuously since 1931., Completed the ~$525M acquisition of OMEGA Engineering from Spectris in July 2022, forming DwyerOmega., Grew to a portfolio of brands including Dwyer, Omega, ACI, Miljoco, Weiss Instruments, and UFM.

## Products & services

- **Differential Pressure Transmitters & Gauges** — The category Dwyer is known for - Magnehelic-style gauges and transmitters (e.g. MSX Magnesense, DigiMag, Series 3100D explosion-proof) for air and gas pressure in HVAC and process applications.
- **Temperature Sensors & Thermocouples** — OMEGA's core: thermocouples, RTDs, thermowells, and metrology-grade temperature devices used from labs to heavy industry.
- **Flow & Level Instrumentation** — Flow meters, flow switches, and level measurement instruments for water/wastewater, chemical, and food and beverage processing.
- **Gas Detection & Indoor Air Quality** — Gas detection monitors and IAQ sensors, expanded significantly through the 2025 Macurco acquisition.
- **Data Acquisition & Data Loggers** — Data loggers (e.g. Model DL7) and DAQ systems for recording temperature, humidity, pressure, strain, voltage, current, and events.
- **Force, Strain, pH & Conductivity Sensors** — Load cells, strain gauges, and process analytical sensors for pH and conductivity across industrial and laboratory settings.
- **Calibration & Technical Services** — Calibration, application engineering, and technical support - the services layer that surrounds the product catalog.
