About Precision Sensors

Precision Sensors, located in Milford, CT, was founded over 50 years ago to serve the aerospace and defence industries. Acquired by United Electric Controls Company in 1989, Precision Sensors designs and manufactures electromechanical and solid state pressure, vacuum, liquid level, temperature, flow and altitude/airspeed switches for commercial and military aerospace, and semiconductor process markets. Like UEC, Precision Sensors delivers fundamental value as leaders in safety, alarm and shutdown.

What Precision Sensors Do

Precision Sensors develops and supplies a wide range of robust electromechanical and solid-state devices that detect, monitor and control critical operational parameters. Their core product lines include:

• Pressure & Vacuum Switches — for monitoring air, gas, or fluid pressure in systems.

• Flow & Liquid Level Switches — for detecting flow rates and fluid levels in tanks, pipes or exhaust/purge systems.

• Temperature Devices — sensors for monitoring thermal conditions in diverse settings.

• Altitude / Airspeed & Environmental Sensors — used especially in aerospace applications for measuring altitude, airspeed or environmental conditions.

These products are used in critical control, monitoring and alarm-triggering functions — helping safeguard personnel, equipment and industrial processes.

Industries Served

Precision Sensors serves a wide range of high-demand industries, including:

• Aerospace & Defence — supplying sensing and switching solutions for commercial and military fixed-wing and rotary aircraft, engines, ground vehicles and space applications.

• Semiconductor & Industrial — providing sensors and switches for ultra-clean gas distribution, chemical delivery, exhaust/purge gas systems, DI water systems and other industrial process environments.

This cross-industry presence demonstrates their versatility and commitment to reliability in both highly regulated and industrial environments.

Commitment

Precision Sensors operates under rigorous quality management standards, with certification to ISO 9001:2015 and AS9100 Revision D, assuring customers that their products meet the highest levels of reliability and consistency.

Their mission is to deliver cost-effective, dependable solutions that protect people, equipment, and processes. They understand that excellence today does not guarantee excellence tomorrow, and so they commit to continuous innovation and performance leadership.
