-
Wide measurement compatibility: Measuring medium: gas, vapor, liquid can be a variety of occasions.
-
high measurement accuracy: monocrystalline silicon principle can be as high as 0.1% FS or 0.2% FS;
-
fast response time: amplifier components damping constant of 0.1s; sensor time constant of 0.1s ~ 1.6s, depending on the range and range ratio;
-
self-diagnostic function: if the sensor or circuit failure, the automatic diagnostic function automatically outputs 22.0mA, which serves as a fault warning.
The flange mounted differential pressure transmitter is used to measure the pressure, level or density of liquid, gas or vapor. The use of monocrystalline silicon differential pressure sensing element or fully sealed capacitor, so that the pressure measurement has a high measurement accuracy at the same time to ensure excellent stability and reliability, the pressure by the capillary tube within the tank filled with silicone oil (or gas liquids) to the main body of the color changer, and then by the transmitter body of the x-chamber and the amplifier circuit board, will be converted to pressure or differential pressure 4 ~ 20mA DC signal output. Users can calibrate, set and configure the transmitter through HART communication hand manipulator. Widely used in chemical industry, metallurgy, water conservancy, electric power, petroleum and other occasions.
