A proportional controller operated pneumatically is used to control temperature within the range of 65°F to 100°F.The measured temperature goes for 71°F to 78°F with the set point held constant when he controller is adjusted so that the output pressure goes from 3 psi (valve fully open) to 15psi (valve fully closed). Find the Proportional band.
