Bourns Expands Sensor Line for Extended Temp Applications


New Pressure Sensor Features Ceramic Port to Enhance Compatibility with Certain Harsh Media

RIVERSIDE, Calif. - Bourns, Inc., further expanded its line of environmental sensors to include a new pressure sensor. Bourns Model BPS140 pressure sensors are based on state-of-the-art Microelectromechanical Systems (MEMS) technology, which provides extremely accurate condition readings in a miniature package size. Designed to deliver high sensitivity/accuracy and long-term reliability, the new BPS140 pressure sensors offer extended temperature capability and certain harsh media compatibility.

Model BPS140 is a robust device with a structure that is capable of handling high pressure ranges (15 to 500 PSI) even at high temperatures. Another advantage of Bourns' newest pressure sensor design is that its structure is combined with backside pressure measurement that minimizes the number of media-sensitive wetted materials. The purpose of this backside sensing design is to ensure the measured media only touches the backside of the measurement element.

Bourns' new sensor family offers stable performance over the product's lifespan, and the ability to work with a wide range of pressures offering a Total Error Band of 2.5 % FS over a temperature range of –40 °C to 150 °C (Six-Sigma process), and a lifetime drift of 0.5 % FS. These features make the BPS140 pressure sensor an ideal solution for a range of industrial, energy, heavy equipment, building & home control and medium/low risk medical designs.

Bourns' Model BPS140 pressure sensors are available now, and are RoHS compliant. Bourns also offers port configuration and calibration customization. For more detailed product information:
