The fossil oil temperature and pressure important parameter of pressure and temperature testing apparatus can be used to measure the in oil and chemical industry. The apparatus consist of sealed crust, pressure sensor, temperature sensor, data acquisition and restore circuit, low-energy consumption battery. And it can automatically complete time-lapse data acquisition and storage, and turn on-off the power of data storage circuit, and record groups of acquired data, and complete the data uploading, displaying, printing, verifying and parameters setting through the communication with upper-level computer. It is of the features of simple operation, high accuracy, long-time working, low energy consumption and anti-jamming etc. The Down-Level computer adopts single-chip of PIC16F88 as core component with high performance-cost ratio to realize automatic data acquisition, data storage and communicating with Upper-Level computer. The Upper-Level computer accomplishes sample taking time setting, parameters setting, real-time verifying, data processing. Because of the nonlinear of thermal resistance, the linear rectification is realized in the software design of the Upper-Level computer.
