(一)概述上海第二电表厂生产的MY5型41 LED单光柱显示仪是采用专用电路、基准电压源、驱动单元及高亮度LED光柱组成的微型化仪表,具有显示亮度高、功耗小、性能可靠、使用简便、外形小、抗干扰能力强的优点。本仪器作为DDZ-S系列仪表的模拟量显示表头,如果配上各种不同模拟量输出的一次仪表,就能直观地显示自动化系统中流量、温度、压力、重量、转速等非电量的设置值和控制值。显示仪的外形如图1所示。
(1) Overview The MY5 41 LED single-beam display instrument produced by Shanghai No.2 Ammeter Plant is a miniaturized instrument composed of special circuit, reference voltage source, driving unit and high-brightness LED light beam. It has the advantages of high brightness, low power consumption, Reliable performance, easy to use, small form factor, anti-interference ability. The instrument as a DDZ-S series analog meter display header, if accompanied by a variety of different analog output of a meter, you can visually display the automation system flow, temperature, pressure, weight, speed and other non-power settings Value and control value. Display appearance shown in Figure 1.
