Sigma-Netics, Inc. is a privately held company based in Riverdale, New Jersey. It makes pressure switches, pressure transducers, metal bellows and metal bellows assemblies. The company describes itself as a global manufacturer of these products. Its parts are used in industrial, military and aerospace equipment.

The company's pressure switches are built to be rugged. The site says they keep working in harsh settings, including high pressures, heavy vibration and extreme temperatures. Its pressure transducers are described as accurate and reliable in tough industrial and aerospace uses. The site also lists pressure and vacuum switches with long cycle life.

Sigma-Netics also makes metal bellows. The site lists hydroformed bellows, edge welded bellows and electrodeposited nickel bellows. These come in brass, phosphorous bronze, beryllium copper, stainless steel and Monel. The company also makes thin-walled metal tubing with very low tolerances. It offers soldering, brazing and welding work, and assemblies such as liquid filled thermostats.

Some of the bellows go into HVAC, medical and electrical distribution products. The site says others are used in flight-critical aerospace applications. The company has a commercial space product area. Its news posts describe a space-rated pressure transducer and a study of welding with high-speed imaging.

The site says the company was founded in 1960. It says its ruggedized pressure and vacuum switches have served mining, oil and gas, aerospace, military and industrial customers for more than 50 years. The company runs a 30,000 square foot plant in New Jersey. A second plant in Virginia supports production of its pressure transducers.

The website has technical resources. These include white papers, data sheets, brochures, videos and glossaries for pressure switches and transducers. There is a configure and quote tool, a press releases page and a page on quality certifications. The site lists contact details, links to LinkedIn and YouTube, and a careers page.
