Combined flow, pressure and temperature sensor
Abstract:
The invention relates to a device for measuring pressure, temperature and/or flow velocity. It includes a sensor (6) with a sensor support body (13) provided with a diaphragm (15) covering a cavity (14) formed in the support body (13). A pressure sensitive element (41) is mounted on the diaphragm, for recording pressure. Furthermore, a temperature sensitive resistor (42) is mounted in the vicinity of the pressure sensitive resistor and has a known temperature dependence, for recording temperature. It also includes an electrical circuit (43, 44, 45, 46) selectively outputting signals from either of the pressure sensitive element and the temperature sensitive resistor.
Abstract(Chinese):

本发明涉及一种用于测量压力，温度和/或流速的装置。 它包括具有传感器支撑体（13）的传感器（6），传感器支撑体（13）设置有覆盖形成在支撑体（13）中的空腔（14）的隔膜（15）。 压力敏感元件（41）安装在隔膜上，用于记录压力。 此外，温度敏感电阻器（42）安装在压敏电阻附近，并具有已知的温度依赖性，用于记录温度。 它还包括选择性地输出来自压敏元件和温度敏感电阻器中的任一个的信号的电路（43,44,45,46）。
