Pressure sensors are not a specific brand but a category of devices used to measure pressure in various industrial and commercial applications. However, leading manufacturers of pressure sensors include companies like Honeywell (USA), Siemens (Germany), and Endress+Hauser (Switzerland). These sensors are widely used in industries such as automotive, aerospace, healthcare, and manufacturing. Key products include piezoresistive, capacitive, and optical pressure sensors, which cater to different precision and environmental requirements. Companies like Omega Engineering (USA) and WIKA (Germany) also specialize in high-quality pressure measurement solutions for diverse industrial needs.
