多用比较式气压计校验台,是根据活塞式油压校验台的基本原理自行设计改进的,因为活塞式油压校验台满足不了检定制氧自控仪表的要求。经过半年多的使用,校验各种压力仪表都能达到精度要求,特别是制氧车间停机检修时,把这台仪器推到现场,很快就能把自控仪表全部校验完毕。工作非常方便,效率很高。而且能实现远距离传送校验和多个同量程 Multi-purpose comparison barometer calibration platform is based on the basic principles of piston-type hydraulic pressure calibration platform to improve their own design, because the hydraulic piston-type checkout bench can not meet the requirements of oxygen-controlled instruments. After more than six months of use, calibration of various pressure instruments can achieve the accuracy requirements, especially when the oxygen plant downtime maintenance, push this instrument to the scene, will soon be able to check all the self-control instrumentation is completed. Work is very convenient, high efficiency. But also to achieve long-distance transmission of checksum and the same range
