WARNING!
The transmitter has been developed for an operating temperature of -40...+85°C/ -40°F...+185°F.
To avoid destruction or damage of the device, always assure that the operating temperature or
ambient temperature does not exceed the permissible range. The thermowell also transfer the
process temperature to the transmitter housing. If the process temperature is close to or
exceeds the maximum temperature of the transmitter, then the temperature in the transmitter
housing can rise above the maximum permissible temperature. One way to decrease the head
transfer via thermowell is to install the transmitter further away from the heat source. Inversely
similar measurements can be done if the temperature gets below specified minimum
temperature.
