QDF70B Air Pressure Transmitter Differential 4-20mA 0-5V Wind Pressure sensor
QDF70B Air Pressure Transmitter Differential 4-20mA 0-5V Wind Pressure sensor
Introduction
<1>. QDF70B Air Wind Differential Pressure Transmitter, adopts imported high-precision, high stability micro-pressure chip, and aluminum alloy shell. The two pressure interfaces are M10 screw thread and plug structure. (Customer can choose the size of pressure interfaces.)
<2>. It can be directly installed on the measuring pipe or connected by the pressure pipe, easy to install and use. Milli voltage, standard voltage, current, frequency signal output are available to choose.
<3>. This pressure 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.
