差压变送器在活塞式压力计计量中的应用

Differential pressure transmitter in the application of piston type pressure gauge measurement

活塞式压力计作为一个压力量量值传递的重要计量标准装置,其重要性可想而知。但是活塞式压力计的计量过程对操作者的实际操作等一系列经验积累水平有非常高的要求,且繁杂的操作过程会造成计量工作者的主观意愿引入其他误差,影响量值传递的准确性。尤其是在活塞调平这一过程中,没有相当的经验积累和活塞式压力计操作手感是根本无法完成的。针对这一难题引入差压变送器到活塞式压力计的计量过程中,简化操作过程,使活塞式压力计的计量更容易被学习和掌握,保证压力量量值传递的准确可靠。

Piston type pressure gauge as a pressure force dissemination of important measurement standard device.Piston type pressure gauge measuring process,and a series of practical experience of the operator level have very high requirements.Piston type pressure gauge measuring multifarious operation process will cause the subjective intend to introduce other error measuring workers.These factors influence the accuracy of the dissemination.Especially in the process of leveling the piston,not quite the experience accumulated and piston type pressure gauge handle is simply can＇t do.The introduction of differential pressure transmitter to the measurement process of piston manometer,simplifies the operation process,make the piston type pressure gauge measurement is more easy to learn and master,ensure the pressure forces the dissemination of accurate and reliable.
