Sensor Type Temperature Limits
Sensor type temperature limits are determined by your choice of Input Type,
Sensor Type, and Temperature Units.
For example, you can configure a channel with the following parameters:
•
Input Type = RTD (Ohms)
•
Sensor Type = 100 Ohm PT 385
•
Temperature Units = Celsius
In this case, the Scaling parameters are set as follows:
•
Low Signal = -200.0000 °C
Low Engineering = -200.0000
•
High Signal = 870.0000 °C
High Engineering = 870.0000
IMPORTANT
When you make the configuration choices listed previously, the Scaling
parameters are automatically set on the Configuration tab of the Module
Properties dialog box and cannot be changed in the software.
The Low Signal value equals the Low Engineering value. The High Signal value
equals the High Engineering value.
