A signal (termed the "measured value") which is proportional to the pressure difference is then transmitted by means of a "differential pressure transmitter" to the recorder-controller.
正比于压差的信号（称为测量值）通过“压差变送器”被送至记录控制器。

By analyzing the architecture of simulation Engine, it was viewed as a special federate and composed of the three components: simulation scheduler, simulation controller and data recorder.
Using the central control system PLC, intelligent temperature controller and pressure gauge to replace the three pen recorder to realize the closed loop circulation and record of outer temperature.
