13 Specifications
Specifications for sensor and transmitter are listed in the General Specifications of the
corresponding product family.
13.1 Ambient conditions
Rotamass Total Insight can be used at demanding ambient conditions.
In doing so, the following specifications must be taken into account:
As ambient temperature is intend the air surrounding the device.
Allowed ambient and storage temperature of Rotamass Total Insight depends on the be-
low components and their own temperature limits:
▪ Sensor
▪ Transmitter
▪ Connecting cable between sensor and transmitter (for remote design type)

1)
If the device is operating outdoors make sure that the solar irradiation does not increase
the surface temperature of the transmitter higher than the allowed maximum ambient
temperature. Transmitter display has limited legibility below -20 °C (-4 °F)
2)
Check derating for high fluid temperature, see Process fluid temperature range,
Process conditions and Allowed ambient temperatures for sensor.
