问与温度变送器配用的记录仪,各个温度刻度点的输入毫安值能否按比倒(等分)计算? 答这是一个重要的实际性问题。不少用户对这类仪表进行入厂检验、修理、调校时,按比例(等分)的方法计算仪表的输入毫安值,结果证明是不行的。一台合格的仪表被误认为不合格,甚至错误地要求制造厂进行三包修理或用户自己进行修理。一些引进产品(如四川仪表四厂的ER系列、西安仪表厂的Ⅰ系列等)的记录仪内部有线性化装置,刻度盘是等分的,按比例方法计算输入毫安值。国产记录
Asked with the temperature transmitter with the recorder, the temperature of each point of the milliampere input value can be calculated by the ratio (down)? This is an important practical issue. Many users of such instruments into the factory inspection, repair, calibration, the proportionate (equal) method of calculating the input mA value, the result proved not. A qualified instrument was mistaken for failure, or even mistakenly require the manufacturer to repair three packs or the user to repair. Some imported products (such as Sichuan Instrument Factory ER Series, Xi’an Instrument Factory Series I, etc.) of the recorder linearization device, the dial is divided into equal parts, according to the method of calculating the input mA value.
