Abstract
A spring-operated relief valve can include an adjustable main spring to bias the valve closed and a load cell that is configured to measure a force exerted by the main spring. Measurements from the load cell can be used to determine a set or crack pressure in the spring-operated relief valve, and to monitor operation of the spring-operated relief valve.
