Product Introduction
<1>. QDF70B differential air pressure transmitter, adopting the imported high-precision, high stability micro-pressure chip.
<2>. The shell is aluminum alloy structure. The two pressure interfaces are M10 screw thread and cock structure. (Customer can choose the size of pressure interfaces.) It can be directly installed on the measuring pipe or connected by the pressure pipe, easy to install and use.
<3>. Milli voltage, standard voltage, current, frequency signal output are available to choose.
<4>. QDF70B transmitter is widely used in petroleum, chemical industry, metallurgy, electric power and other fields. It effectively control in power and coal industries, such as boiler ventilation and underground ventilation.
