由于热敏记录具有不用墨水、记录清晰、维护量小、能保持仪表内清洁卫生等优点,在新型仪表中的应甩越来越广泛。针对旧型仪表使用墨水记录存在的问题,我们订购了上海记录纸厂生产的热敏记录纸,用于EWY型电子电位差计、D—610电感应差压显示仪、CF型机械浮子差压计等旧型仪表,取得了很好的效果。现小结如下: 1、电热笔的制作为了减少回路损耗、增加热笔与回路的电阻比值,我们将电阻丝绕在笔尖上对笔尖间接加温,从而取得加热记录纸的温度。经实践应用效果很好。
Because of thermal recording with no ink, clear recording, small maintenance, to maintain the metrological advantages of cleaning, etc., in the new instrument should be more and more rejection. We have ordered the thermal recording paper produced by Shanghai Recording Paper Mill for EWY electronic differential potentiometer, D-610 differential pressure indicator, CF mechanical float differential pressure gauge And other old instruments, and achieved good results. Now summarized as follows: 1, the production of electric pen In order to reduce the loop loss, increase the hot pen and loop resistance ratio, we will resistance wire wound on the tip of the nib indirect heating, so as to obtain the temperature of the heating recording paper. The practical application of good results.
