新颖的数字仪表以数字表示并自动记录被熔金属的温度,其测量误差为±0.3％±1°C。它与作高温测量的易损热电偶联用(几种工业钢到1650℃和某些磁钢到1750℃),也可与测量金属或非金属溶液的一般热电偶联用。目前,采用的连续记录热电偶信号的图示方法比较费时,而且不够精确。数字指示仪也可测量许多其他气体和液体的温度,其中包括熔化玻璃和陶瓷的温度。这种新颖的指示仪由两部分组成(见图),左端是本身的指示部分,右端是增加的时间发送器和控制部分。
The new digital gauges digitize and automatically record the temperature of the molten metal with a measurement error of ± 0.3% ± 1 ° C. It is used in combination with a thermocouple for high temperature measurements (several industrial grades up to 1650 ° C and some magnets up to 1750 ° C), as well as common thermocouples for the measurement of metallic or non-metallic solutions. At the present time, the method used to record the thermocouple signals continuously recorded is time-consuming and not accurate enough. The digital indicator can also measure the temperature of many other gases and liquids, including the temperature of the molten glass and the ceramic. This novel indicator consists of two parts (see figure), the left part is the indicator part of itself and the right part is the added time transmitter and control part.
