“气动色带指示仪”(QXZ-113),通常与气动差压变送器或气动压力变送器相配套,用来连续测量显示被测液体的液面高度。如果“气动色带指示仪”装上非等分的刻度的标尺,装上平方根的刻度的标尺,也可以连续测量显示流体的流量值。气动色带指示仪由于装有小灯珠,因而它显示液面或流量比较直观、形象、醒目。同时,它还带有上限及下限的电接点报警装置,并且稳定、可靠,受到用户的好评。下面分述它的故障维修的七个例子: “Pneumatic Ribbon Indicator ” (QXZ-113), usually with pneumatic differential pressure transmitter or pneumatic pressure transmitter matched, used to continuously measure the liquid level of the measured liquid display. If the “Pneumatic Ribbon Indicator ” is equipped with a non-equally divided scale and a square root scale, it is also possible to continuously measure the flow rate of the fluid. Pneumatic ribbon indicator with a small lamp beads, so it shows the level or flow more intuitive, image, eye-catching. At the same time, it also has the upper limit and lower limit of the electric contact alarm device, and stable, reliable, praised by users. Here are seven examples of fault maintenance:
