Measured value error (under reference conditions)
• Measuring error
• Dead zone
• Additional contribution of
analog output
• Influence of pressure
(air, 20°C)
• Long-term stability
• Repetitive accuracy

Flange material may be either 316/316L or 1.4571 at the discretion of Siemens
Milltronics Process Instruments Inc. Actual flange material will be noted on the
side of the flange.
