Title:
PRESSURE AND TEMPERATURE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/071693
Kind Code:
A1
Abstract:
A pressure and temperature measuring device, comprises a case (10), a pressure sensor (20) and a circuit board (30) which are housed in the case (10). The pressure sensor (20) is connected with the case (10) to form a sealed housing cavity. An object to be measured flows into the housing cavity through an inlet hole (11) on the case (10). The pressure sensor (20) senses the pressure signals of the object to be measured in the housing cavity, and the circuit board (30) transforms the pressure signals into electric signals and outputs them. A temperature sensing element is disposed on the circuit board (30). The temperature sensing element senses the temperature signals of the object to be measured, and the circuit board (30) transforms the temperature signals into the electric signals and outputs them. The pressure and temperature measuring device has a simple structure, is convenient to install, and further improves its stability and measurement precision.
