摘要：
In a method for estimating a remaining lifetime of a solenoid coil of a valve controller operating in a process control system, a record of a duration of activation of the solenoid coil is maintained during operation of the solenoid coil. An operating temperature of the solenoid coil is determined. An estimate of the remaining lifetime of the solenoid coil is generated based on the duration of activation of the solenoid coil and the operating temperature of the solenoid coil.
