For process temperatures between -50 … +195 °C the lower ambient temperature on the housing
can be min. -50 °C (with PLICSCOM) or -60 °C (without PLICSCOM).
For process temperatures lower than the maximum values given in the above tables, higher ambient
temperatures on the housing may be permissible. For details, contact VEGA.
The application conditions during operation without hazardous atmospheres can be found in the
manufacturer information in the operating instructions manual.
