JJG 882-2019《压力变送器》检定规程对标准器的要求及选择

JJG 882-2019 "Pressure Transmitter" Verification Regulations for the Standard Requirements and Selection

压力变送器是将压力变量转换为可传输的标准信号进行传输的仪表。能够将现场作业的压力模拟量转换为长距离传输便于观测控制的数字量,在生产企业中有着广泛的使用,具有不可代替的优势。JJG 882-2004压力变送器检定规程编写至今已经有16年了,[1]因时代发展和技术进步,很多内容已经不适应当前市场环境的要求,新规程在压力变送器等级划分和标准选择上都有较大调整,在建立计量标准时对计量标准器提出来新的更高要求。

pressure transmitter is an instrument that converts a pressure variable into a standard signal that can be transmitted.It can transform the analog pressure of field operation into the digital quantity which is easy to observe and control in long distance transmission.The verification regulation of JJG 882-2004"Pressure Transmitter"has been written for 16 years now.[1]Due to the development of the times and the progress of technology,many contents have not adapted to the requirements of the current market environment,the new regulation has a great adjustment on the grading and standard selection of pressure transmitter,and puts forward a new and higher requirement for the standards when establishing the standards.
