Trainer: raquel 2013. 8. 16, 2, i. Measurements of differential transporters, measurement of liquid pressure at a certain location, conversion of electrical circuits through internal signals, with standard 420ma current output. 1, make-up principle, output-input relationship, conversion factor for the d measurement component; k amplifier magnification factor; f feedback factor for the feedback component. ,3,4, the quantification adjustment is designed to match the upper value of the carrier's output signal to the upper value x of the measured range. The method used to adjust the scale is usually the feedback factor f that changes the feedback component. The larger f, the bigger the scale; the smaller f, the smaller the scale. 2, quantification, 5, zero-point adjustment and zero-point migration are intended to match the lower limit of ymin for the carrier output signal with the lower limit xmin for the measured signal. , zero-point adjustment, positive migration, negative migration, zero-point adjustment and zero-point migration, 6, 2, example analysis of the differential deliveryer structure of type 3051, working principles, mode of operation of type 3051, external structure of type 3051 differential deliveryer, structure of type 7,3051 differential deliveryer, structure of type 2, 3051 differential deliveryer, structure of type 8,3051 differential transporter measurement head structure, structure of type 2,3051 differential transformer, 9, differential pressure from two-side cavity cavity tubes directly on the transducer sensor's side-segregation film, by means of a sealed fluid transfer in the film to the measuring component, the measurement element converts the differential signal to its corresponding telecommunications number, and converts it to the standard 420ma telecommunications output through amplification treatment. , in summary, 10,
