Q

An automatic temperature controller, with a net output pressure of 15 psi and a full scale range of 15°F, would have a sensitivity ratio of __________.

🔍 Key Concepts

• Sensitivity (gain) of a controller as the ratio of output change to input change • How to use net output pressure range and temperature range to compute a rate (psi per °F) • Basic formula: sensitivity = (change in output units) / (change in input units)

💭 Think About

• What is the total change in output pressure (in psi) from minimum to maximum for this controller, and what temperature change does that correspond to? • If you divide the net output pressure span by the full-scale temperature span, what units do you get? • Which answer choice has units that match "psi per °F" when you use that ratio?

✅ Before You Answer

• Be sure you are using the entire net output span (not just 1 psi or 1°F) in your calculation • Confirm that your final number has units of psi/°F, not °F/psi • Double‑check your division: larger output span divided by smaller temperature span should give a larger psi/°F value, not smaller
