48 Digital Position-Proportional Controllers E5EZ-PRR
Ceramic Furnace Position Proportional Control
Reading the extent of the valve's opening with a potentiometer, and using open and close tuning control is referred to as position proportional con-
trol or on/ off servo control.
■ Examples of Application
When using position proportional methods to control gas combustion furnace valves, position propor-
tional control should be applied. See the following figure for measurement devices:
The SP ramp function allows limits to be placed on temperature changes
which control the temperature within a specific range. This is useful for
ceramic furnace, in which severe temperature changes may cause dam-
age or corruption.
