By presenting the theory of LD301 difference pressure transmitter and the solution for zero point excursion, its performance and advantage are introduced.
通过介绍LD 301差压变送器的原理及零点漂移的解决办法，介绍了它的性能和使用优势。
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。
