Introduction . QDF70B Air Wind Differential Pressure Transmitter, adoptsimported high-precision, high stability micro-pressure chip, andaluminum alloy shell. The two pressure interfaces are M10 screw thread and plug 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. Milli voltage, standard voltage, current, frequency sign-al output are available to choose. .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 and underground.Technical parametersMeasure MediumPressure TypeLED/LCD Differential PressureMeasuring Range-10~0~10KPaPower Supply12VDC~36VDC(Standard24VDC)Output Sign-al4~20mA, 1~5V, 0~5V, 0~10V, RS485Accuracy0.2%FS;0.5%FSMedium Temperature-40~85Compensation Temperature0~50Ambient Temperature-20~85Temperature Effect on Zero±0.03%FS/Sensitivity Temperature Drift±0.03%FS/Overload Pressure300%FSResponse Time10msWaterproofIP65MaterialAluminium AlloyProcess ConnectionM10X1.5/1/8''NPT(Customized)Explosion-proof GradeExiaII CT5
