(54)DETERMINING DIAPHRAGM LIFE ON A PRESSURE REGULATOR


(57) Apparatus are configured to monitor lifespan of parts on a pressure regulator. These configurations may include sensors that generate signals in response to movement of parts on the pressure regulator. Processing circuitry can process the signals to identify data that corresponds to deflection of a spring inside of the pressure regulator. This data may correlate with duty cycle of a diaphragm. In one implementation, utilities can use the duty cycle to gauge useable lifespan of the diaphragm as well as other operating conditions that may prevail on the pressure regulator.
