笔者长期从事仪表计量检定工作,从实践中摸索出一种EJA压力变送器超差非计算调整方法,现总结与大家分享。一、问题发现EJA压力变送器质量稳定,在市场上应用广泛,我公司也大量使用。但在周期检定中发现一部分EJA压力变送器在使用标准气源,同时应用BT200手操器零位调整后,发现量程低点值在4.000mA,但量程高点 The author has long been engaged in measuring instrument calibration work, from practice to explore a EJA pressure transmitter non-calculation adjustment method of tolerance, is now summed up to share with you. First, the problem found EJA pressure transmitter quality and stability, widely used in the market, our company also extensive use. But in the cycle test found that part of the EJA pressure transmitter in the use of standard gas source, while applying zero adjustment BT200 terminal, found the range low value at 4.000mA, but the high range
