By statistic and analysis for well testing data measured by electric pressuregauge formerly, it is found that formation temperature data is very important for oil testing procedure.
There is an oilpressure sensor near the oil pump that monitors pressure and sends this information to a warning light or a gauge on the dashboard.
在油泵附近有个油压力传感器，它能检测油的压力并传递给警示灯或仪表板上的油量表。

With piston oxygen pressuregauge, pressuregauge calibration must adopt isolation tank and water will do spacer piston pressuregauge of oil isolation, make water into oxygen table.
