Abstract: An actuator of a process control device continuously monitors actuator force and records high force values at each position point by continuously executing a routine in a processor of the actuator. The routine includes receiving from a position sensor a current position value indicating a position of a valve element in the valve, and from a force sensor a current force value indicating a force applied by the actuator. The routine also includes retrieving, from a memory device coupled to the processor, a previous force value measured at the current position, and comparing the current force values for the current position with the previous force value for the current position. If the current force value for the current position exceeds the previous force value for the current position, the routine replaces the previous force value for the current position with the current force value for the current position in memory.

Abstract: An actuator assembly includes a cylinder disposed in an actuator housing, the cylinder having a cylinder interior is in fluid communication with a source of pressurized fluid. A ram member has a piston head within the cylinder interior, and pressure on the piston head moves the ram member. An end of the ram member acts on a collar having a collar interior, and an end of a rod member is disposed within the collar interior. The rod member is displaceable relative to the collar such that the end of the rod member does not contact the collar. Accordingly, fluid in the cylinder interior acting on the ram member may expand due to thermal expansion without damaging a hard stop at an opposite end of the rod member and without losing system pressure by triggering a relief valve.

Abstract: Methods and apparatus are disclosed for automatically detecting the failure configuration of a pneumatic actuator. A control module is operatively coupled to the actuator, and the actuator is operatively coupled to a valve having a flow control member. When a number of pilot valves included in the control module is indicative of a double-acting actuator, the failure configuration of the actuator is determined based on the number of pilot valves. When the number of pilot valves included in the control module is indicative of a single-acting actuator, the failure configuration of the actuator is determined by comparing a first measurement value obtained in response to moving the flow control member in a first direction to a first position and a second measurement value obtained in response to moving the flow control member in a second direction opposite the first direction to a second position.

Abstract: Methods and apparatus for changing actuator output torques are disclosed. An example method includes decoupling a first end cap from a body of an actuator. A first spring assembly is positioned within a first outer chamber defined by the first end cap and the body. A first end of the first spring assembly is positioned adjacent a surface of a first piston. A second end of the first spring assembly is positioned adjacent the first end cap when the first end cap is coupled to the body. The method includes positioning a first spacer within the first outer chamber and coupling the first end cap to the body. The first spacer changes a distance between the first and second ends of the first spring assembly when the first end cap is coupled to the body to change an output torque of the actuator.

Each digit gear has a first portion including a first set of teeth disposed about an entire circumference of the first portion and a second portion including a second set of teeth disposed about only a portion of a circumference of the second portion. Each digit gear is to correspond to a respective digit in a code representing an absolute position of a shaft. A respective idler gear between each adjacent pair of the digit gears is to be intermeshed with the first set of teeth of one of the digit gears and the second set of teeth of the other one of the digit gears.

Abstract: Methods and apparatus of using customizable templates in process control systems are disclosed. An example method includes initializing a first process control device associated with a first protocol based on a template file and a first parameter definition file. The template file includes global variables and associated values. The first parameter definition file defines a relationship between the global variables and first local variables of at least one of the first process control device or the first protocol. The example method also includes initializing a second process control device associated with a second protocol based on the template file and a second parameter definition file. The second parameter definition file defines a relationship between the global variables and second local variables of at least one of the second process control device or the second protocol. The first protocol is different from the second protocol.
