referenced to 20°C ambient temperature
Digital display :
8- digits 7- segment-LC-display character height 6 mm
Process-/ Ambient temperature :
The dependency of the process temperature from the
ambient temperature is shown in fig. 7a to fig. 7c.
The internal temperature of the electronic transmitter
can be indicated on the display or checked via HART
communication.

- Range :
-25 °C to +70 °C
- Accuracy : ± 5 °C
Transportation- and Storage condition :
-40 °C to +70 °C
