Pressure Sensors

Bourns, Riverside, CA, offers the Model BPS140 pressure sensors based on MEMS technology. They can handle high pressure ranges (15 to 500 PSI) even at high temperatures. The sensors’ structure is combined with back-side pressure measurement that minimizes the number of media-sensitive wetted materials, ensuring that the measured media only touches the back side of the measurement element. The sensors work in a temperature range of -40 to 150 °C.
