Temperature Compensation (P660 to P664)
P660 Temp Source
Source of the temperature reading used to adjust the speed of sound.
The SITRANS LU01 uses the TS-3 temperature sensor assigned to the transducer. If one
is not connected, the ultrasonic/temperature transducer is used. If the transducer does
not have an internal temperature sensor, the Temp Fixed (P661) value is used.
If the acoustic beam atmosphere temperature varies with distance from the transducer,
connect a TS-3 Temperature Sensor and ultrasonic / temperature transducer, and select
average.
P661 Temp Fixed
Use this feature if a temperature sensing device is not used.
Enter the temperature (in °C) of the atmosphere within the transducer acoustic beam. If
the temperature varies with distance from the transducer, enter the average temperature.
P664 Temperature
View the transducer temperature in °C.
Value is displayed when is pressed in RUN mode.
