| Title | Part 21 Report - Defective Barton Differential Pressure Switches |
| Event Description | The following is a synopsis of information received via facsimile:
Cameron Measurement Systems has issued a product advisory concerning nuclear qualified versions of Barton Model 288A, 289A, 580A and 581A differential pressure indicating switches and blind switches and spare switch assemblies shipped from the Cameron factory. The defect being reported is an out of specification thread on the screws that depress the switch operating plunger which can cause a change in the switch setpoint. The maximum change in screw position observed during testing equates to a switch set point change of approximately 8.4 percent of the instrument's factory calibrated span. The screws of concern did not enter the Cameron stock before February of 2014 for the ones used in the Model 580A and 581A instruments and not before June of 2014 for the ones used in Model 288A and 289A instruments. Cameron recommends that new switch actuator arm assemblies be replaced on any unit that is evaluated to be a concern by their customers. Notification to NRC provided by ISAAC RAMSINI, Manager Quality and Safety, (562) 321-9158. |
