13.2 Environment
Ambient temperature
range
The following values apply up to a process temperature of +85 °C (+185 °F). At higher
process temperatures, the permitted ambient temperature is reduced.
• Without LCD display:
Standard: –40 to +85 °C (–40 to +185 °F)
• With LCD display: –40 to +85 °C (–40 to +185 °F) with limitations in optical properties,
such as display speed and contrast. Can be used without limitations up to
–20 to +60 °C (–4 to +140 °F)
• Devices with PVC-coated capillary armor: –25 to +80 °C (–13 to +176 °F)
• Separate housing: –20 to +60 °C (–4 to +140 °F)
Applications with very high temperatures: use diaphragm seals with a temperature
isolator or capillaries. Use a mounting bracket!
If vibrations additionally occur in the application: use a device with a capillary. Diaphragm
seal with temperature isolator: use a mounting bracket!
