Rosemount 3051S
CHANNEL
Select the channel that corresponds to the desired sensor measurement. The 3051S measures both pressure (channel 1) and sensor temperature (channel 2).

Channel 3 and channels
L_TYPE
The L_TYPE parameter defines the relationship of the sensor measurement (pressure or sensor temperature) to the desired output of the AI Block (e.g. pressure, level, flow, etc.). The relationship can be direct, indirect, or indirect square root.
Direct
Select direct when the desired output will be the same as the sensor measurement (pressure or sensor temperature).
Indirect
Select indirect when the desired output is a calculated measurement based on the sensor measurement (e.g. a pressure measurement is made to determine level in a tank). The relationship between the sensor measurement and the calculated measurement will be linear.
Indirect Square Root
Select indirect square root when the desired output is an inferred measurement based on the sensor measurement and the relationship between the sensor measurement and the inferred measurement is square root (e.g. flow).
