The QXZ pneumatic ribbon indicator is matched with a pneumatic differential pressure transmitter (or a liquid level transmitter that outputs a unified standard air pressure star) to display the level of the pressure. This indicator receives the air pressure signal from the transmitter. The liquid level changes are displayed on the panel in the form of light strips and light columns. Like a liquid rising and falling in a container.
There are four types of QXZ start-up ribbon indicator: QXZ-110 type (displays one parameter), QXZ-111 type (displays one parameter. And has an upper limit alarm.) QXZ-112 type (displays one parameter) A parameter with a lower limit alarm). QXZ-113 type (displays one parameter, and alarms with upper and lower limits).
