Calculation of the total deviation

The total deviation of a pressure transmitter indicates the maximum measurement error to be ex-
pected in practice. It is also called maximum practical deviation or operational error.

According to DIN 16086, the total deviation F

total

is the sum of the basic deviation F

perf

and the long-

term stability F

stab

total

= F

perf

+ F

stab

The basic deviation F

perf

consists of the thermal change of the zero signal and the output span F

well as the deviation F

perf

= √((F

)

+ (F

)

The thermal change of zero signal and output span F

is specified in chapter "

Technical data

". The

basic temperature error F

is shown in a graphic. Depending on the measuring cell version and Turn

down, this value must be multiplied with the additional factors FMZ and FTD:

x FMZ x FTD

Also these values are specified in chapter "

Technical data

This applies for a digital signal output through HART, Profibus PA or Foundation Fieldbus.

With a 4 … 20 mA output, the thermal change of the current output F

must be added:

perf

= √((F

)

+ (F
