      有关 记录仪 产品主要应用于现场工艺参数 ,比 如温度、压力、流量、液位等的显示 记录和控制。 In the field of industrial automation , the products related to the recorder are mainly used for on-site process parameters , such as the display , recording and control of temperature, pressure, flow, and liquid level . 随着电子技术的发展,新型的无纸记录仪产品显示出越来越明显的优越性 ,越来越受到人们的亲睐。 However, with the development of electronic technology, the new paperless recorder products show more and more obvious advantages , and they are more and more favored by people.

    没有 机械运动部件, 使用中的维护量少:由于有纸记录仪需要伺服驱动机构 带动记录笔和记录纸的移动, 长时间使用 的情况下 会出现机械老化,造成卡纸、记录笔需要调整等问题; 无纸记录仪 的数据记录在电子芯片内 通过液晶显示屏来显示、翻阅数据, 因此 不存在这些维护问题。 (1) There are no mechanical moving parts, and the maintenance amount during use is small: because a paper recorder requires a servo drive mechanism , which drives the movement of the recording pen and recording paper, mechanical aging will occur under long-term use , causing paper jams The recording pen needs to be adjusted; however , the data of the paperless recorder is recorded in the electronic chip , and the data is displayed and flipped through the liquid crystal display, so these maintenance problems do not exist.

    方便 进一步的数据保存和分析:存储在无纸记录仪内的存储芯片中的历史数据,可以 通过 U 仪表上的USB 数据口将历史数据拷贝出来, 然后 使用厂商提供的分析软件对U 盘中的数据进行读取和数据分析。 (2) The data can be transferred to a computer for further data storage and analysis: the historical data stored in the memory chip in the paperless recorder can be copied through the USB disk and the USB data port on the instrument. , And then use the analysis software provided by the manufacturer to read and analyze the data in the USB flash drive.

    通用性强的功能,比如0 5V, 1 5V , 0 10mA , 4 20mA ( 二线制 ), 4 20mA( 有源 ) , Cu50 , PT100 , 电阻( 0-400Ω , B , S , K , E , J ,T 等信号都可以直接接入,软件设定 以了 (3) Universal input signal function: Due to the advancement of chip technology, the new paperless recorder products have a variety of standard field instrument signals directly connected to it , such as 0 to 5V, 1 to 5V, 0 to 10mA , 4 to 20mA ( two-wire system ), 4 to 20mA ( active ), Cu50, PT100, resistance ( 0-400Ω ) , B, S, K, E, J, T and other signals can be directly connected, software setting That's it . 温度变送器、现场仪表电源等费用。 Can remove the cost of temperature transmitter, field instrument power and so on.

    越来越小 ,而 容量 越来越大 (4) Large-capacity, long-term data recording function: Due to the development of new memory chip technology, large-capacity memory chips are becoming smaller and smaller , but the capacity is becoming larger and larger . 提高无纸记录仪的数据存储能力提供了 方便。 This provides convenience for improving the data storage capability of the paperless recorder . 内部存储容量可 达到248M ,记录时间 达到10 ( 记录间隔 4 分钟一次 ) 以上。 For example, the internal storage capacity of our color paperless recorder can reach 248M , and the recording time can reach more than 10 years ( once every 4 minutes ) .

    部分 无纸记录仪 产品还具有通信功能,可以和工业计算机形成数据通信网络。 (5) Communication function: Most paperless recorder products also have a communication function, which can form a data communication network with industrial computers.

    内置 打印机驱动程序,可以直接外接微型打印机打印历史或实时数据报表、曲线等。 (6) Printing function: Some paperless recorder products also have a built- in printer driver, which can directly connect to a miniature printer to print history or real-time data reports, curves, etc.

    (7) Chinese tag and logo: The new domestic paperless recorder products have a built-in Chinese character library, which can set Chinese tag and logo.
