What Sigma Netics does
Sigma-Netics, Inc. is a privately held US industrial manufacturer founded in 1960 that designs and produces pressure and temperature sensing elements for industrial, military, and aerospace applications. The company operates from a corporate headquarters and manufacturing facility in Riverdale, New Jersey, with a Sensors Division in Yorktown, Virginia. Its product portfolio comprises four lines: ruggedized pressure switches (including UL-rated explosion-proof models for hazardous locations), ruggedized pressure transducers (including radiation-tolerant series for satellite and nuclear reactor applications and submersible vehicle depth transducers), hydroformed and electroformed metal bellows assemblies for pressure sensing and sealing, and — added in 2024 — precision thin-walled metal tubing for biomedical, deep-sea, and defense applications.
The company's underlying technology is rooted in specialized metal bellows manufacturing using hydroforming and electroforming processes, combined with hermetic welding (including TIG) and precision deep-drawing techniques for thin-walled tubing. Products are engineered to address seven critical failure modes — pressure spikes, leaks, temperature extremes, moisture, chemical exposure, vibration, and shock — and are qualified for failure-intolerant applications across aerospace flight systems, oil and gas hazardous locations, satellite propulsion, nuclear reactors, and unmanned underwater vehicles.
Sigma-Netics runs a sales-led, B2B go-to-market with a Configure & Quote sales process on its website indicating custom, specification-driven sales rather than self-serve catalog commerce. Revenue is generated through hardware sales of sensing elements priced on a quote basis. The company markets via a corporate LinkedIn page, a YouTube channel, white papers, data sheets, and a technology news blog targeting engineering buyers. No external funding, acquisitions, parent company, or institutional investor ownership has been disclosed, and the company appears to be founder/management-controlled.

Sigma Netics product offering
Product offeringCore offering
Sigma-Netics designs, manufactures, and supplies high-performance pressure and temperature sensing elements—pressure switches, pressure transducers, metal bellows assemblies, and thin-walled metal tubing—for industrial, military, and aerospace applications. Products are custom-configured and quoted to customer specifications, engineered to withstand contaminants, temperature extremes, vibration, radiation, and pressure spikes in failure-intolerant environments.
Product overview
Sigma-Netics designs and manufactures high-performance sensing elements for demanding industrial, military, and aerospace applications. The company offers four core product lines: Pressure Switches (ruggedized switches for harsh environments including explosion-proof UL-rated models), Pressure Transducers (ruggedized transducers for high pressure and radiation environments including submersible vehicle and radiation-tolerant series), Metal Bellows (hydroformed and electroformed assemblies for pressure sensing, temperature switching, and sealing), and Thin-Walled Metal Tubing (precision deep-drawn tubes with seamless design). These sensing elements work together to provide complete measurement and control solutions for mission-critical systems.
