无线压力采集仪校准装置研究

Design of a Calibration Device for Wireless Pressure Acquisition Instruments

无线压力采集仪使用环境温度与常规测量仪表存在较大差异。为解决无线压力采集仪在不同温度下的压力校准需求,设计了无线压力采集仪校准装置。该装置采用了三段控温的干式恒温炉以及自动压力调节,实现了各温度下的压力自动校准。试验结果表明:该装置功能及测量不确定度满足现有无线压力采集仪的校准对装置的要求,可应用于无线压力采集仪的校准。

Wireless pressure acquisition instruments are widely used for calibrating pressure sterilization and other pressure vessel. The application temperature of wireless pressure acquisition instruments is different from other pressure instruments. A kind of calibration device was designed for wireless pressure acquisition instruments. The device adopts three-section temperature control and automatic pressure regulation,and can be used for automatic calibration of wireless pressure acquisition instruments. The experimental results show that the uncertainty of the device can meet the requirement of the wireless pressure acquisition calibration.
