摘要: Actual valve stem thrust loads in a motor operated are monitored and measured directly by the use of load cells disposed between operator. Direct measurement eliminates errors associated with indirect methods. Analysis actual measurements correlation other operating parameters, such as switch actuation current, provides capability to accurately calibrate operators detect operator problems at an early stage.
