记录仪XBW用于对流量、温度、压力、液面参数进行连续记录。记录系统的记录笔头经常与记录纸脱开。笔头墨水不畅通,平时在这方面保养、维修工作量较大,记录墨水浪费也较大。一、铱金热敏笔的结构对XBW记录仪记录系统采用热敏笔,经约一年时间试用,效果很好。图一为热敏笔线路图,T为交流变压器(变压器功率大小由接热敏笔多少支而定,每支热敏笔功率约0.5瓦),变压器输入电压220伏交流,变压器输出电压3伏交流。W为电位器(型号
Recorder XBW is used for continuous recording of flow, temperature, pressure and liquid level parameters. The recording system’s recording nib is often detached from the recording paper. Pen ink is not smooth, usually in this area maintenance, maintenance workload, record ink waste larger. First, the structure of the iridium thermal pen on the XBW recorder recording system using a thermal pen, after about a year of trial, the effect is very good. Figure 1 for the thermal pen circuit diagram, T for the AC transformer (the size of the transformer power by the thermal pen how many branches may be, each thermal pen power of about 0.5 watts), the transformer input voltage of 220 VAC, the transformer output voltage of 3 V communicate with. W is potentiometer (model number
