Differential Pressure Transmitter Processing - Differential Pressure Transmitter, Absolute Pressure Transmitter submersible pressure transducer
The differential pressure scale of the differential pressure transmitter is usually verified under the condition that the low pressure chamber is open to the atmosphere. When it is installed in the field and the static pressure is used to zero, it is often found that the zero output and the low pressure and low pressure chamber pass through the atmosphere. The zero output of the calibration is inconsistent. Intelligent Pressure Transmitter Company, the difference between the zero output of the high and low pressure chambers entering the same static pressure is called static pressure error, and the static pressure error is differential pressure transmission. One of the main metrological performance indicators for the instrument verification.
The differential pressure transmitter ¼ìÑé is tested as an important indicator before leaving the factory. However, it must be checked again at the use site when it is put into use. For the zero and full scale calibration, the basic error value of the indication is greater than the indication value. When the error limit is allowed, the intelligent pressure transmitter must be processed repeatedly, and the zero point and the range must be adjusted repeatedly until the two are smaller than the allowable error of the indication, and the error of each check point is reduced to a small value. The true zero output must temporarily remove the small signal cut function.
