Mouser Electronics, Inc. (Mansfield, TX) is now shipping the new MPX2053 Series Air Pressure Sensors from Freescale Semiconductor. These sensors provide accurate pressure readings from 0 to 7.25 PSI (0 to 50 kPa) and require only a 10 VDC supply voltage. Pressure is represented by a differential voltage measured across two pins. On-chip temperature compensation and calibration makes writing code for the MPX2053 even easier. This Freescale pressure sensor is available in two models. The MPX2503GP has a single port and measures gauge pressure, or pressure at the port relative to atmospheric pressure. The MPX2053DP has two ports and measures the differential pressure between the two ports. Laser trimming in the manufacturing process allows for precise offset calibration with temperature compensation.
