Applications
■Control with PV select in High temperature firing furnace application
Input 1 and Input 2 are automatically switched at the preset temperature.
For example, a thermocouple is used in the lower temperature range, and a radiation thermometer is used in the higher temperature range, which are switched between each other at the preset point.
>>Merits of introducing this system
- Accurate temperature measurement and control can be achieved with a single controller (at a lower cost) from low to high temperatures.
