Current output (additional error, in relation to the span of 16 mA):
– Zero point (4 mA)
Average T : 0.02 %/10 K, max. 0.35 % over the entire temperature range
K
–40 to +60 °C (–40 to +140 °F)
– Span (20 mA)
Average T : 0.05 %/10 K, max. 0.5 % over the entire temperature range
K
–40 to +60 °C (–40 to +140 °F)
When there is a difference between the temperature for zero point adjustment and the process
temperature, the typical measured error of the sensor is ±0.0002 % of the full scale value/°C
(±0.0001 % of the full scale value/°F).
The table below shows the effect on accuracy of mass flow due to a difference between calibration
pressure and process pressure.

Dependent on the flow:
Flow ³ zero point stability : (base accuracy : 100)
– Maximum measured error: ±base accuracy in % o.r.
– Repeatability: ±½ × base accuracy in % o.r.
Flow < zero point stability : (base accuracy : 100)
– Maximum measured error: ± (zero point stability : measured value) × 100 % o.r.
– Repeatability: ±2/3 × (zero point stability : measured value) × 100 % o.r.
