An equipment inspecting and evaluating system can be used to inspect and evaluate steam traps by detecting a level of vibrations of each trap and the surface temperature of the housing of that trap. The detected vibration level and temperature are used to determine whether or not steam is leaking through that trap and to what extent steam leakage is. An equipment management system is connected to the inspection and evaluation system by a data transmission cable and receives inspection data of the traps from the inspection and evaluation system. The management system analyzes the received inspection data for computing the number of defective traps, the ratio of defective traps to the entire traps, the loss caused by steam leakage, etc.

The method of claim 9, wherein the bias-current profile is subdivided into segments and wherein the magnitude of the bias current in each segment correlates to one of a series of equally spaced points of a displacement range of the clutch actuator. 14. The method of claim 13, wherein the equally spaced points are located at intervals of 0.5 millimeters. 15. The method of claim 13, wherein the actuator control device adjusts the bias-current profile at a current point of actuator displacement, based on the magnitude and direction of the after-regulation as determined under step c) of the method. 16. The method of claim 15, wherein the adjustment of the bias-current profile at the current point of actuator displacement is made according to one of three concepts, namely: a) changing the bias current by a small fixed percentage of a maximum current; b) changing the bias current by an amount commensurate with the amount of after-regulation; and c) changing the bias current in steps of variable magnitude. 17. The method of claim 16, wherein the bias current is subject to one of the two constraints consisting of a maximum limit for the bias current and a maximum limit for a difference in amounts of the bias current in adjacent segments of the bias-current profile. 18. The method of claim 9, wherein the bias current is set as a function of one of the following: operating parameters of the clutch, operating parameters of the clutch actuator, and operating states of the vehicle. 19. A method of regulating a position of a clutch actuator in a vehicle that is equipped with a clutch and a clutch control device, said method comprising the steps of: a) determining actual position values Kactualof the clutch actuator; b) determining targeted position values Ktargetof the clutch actuator; c) determining whether an initial move to a targeted position or an after-regulation to the targeted position is taking place, based on comparing the actual position values and the targeted position values; and d) generating a bias current to the clutch actuator in accordance with the results of steps a) to c). 20. The method of claim 19, wherein magnitude and polarity of the bias current are subject to change when the method runs through a next cycle. 21. The method of claim 19, wherein the clutch actuator has an integrated position sensor to detect the actual position value Kactual. 22. The method of claim 19, wherein the values Ktargetfor the target position determined in step b) of the method are assigned to one of three groups corresponding to three different behaviors of the actuator. 23. The method of claim 22, wherein the groups are defined according to whether successively detected values of Ktargetincrease, decrease, or stay constant from one to the next, and wherein an increasing trend indicates that the clutch actuator is being pushed back from the targeted displacement position; a decreasing trend indicates that the clutch actuator is running ahead of the targeted displacement position; and a constant value is compatible with either of the conditions of the actuator being pushed back and running ahead. 24. The method of claim 23, wherein the values Ktargetare assigned to the group of increasing values if they change monotonically in a positive direction. 25. The method of claim 23, wherein the values Ktargetare assigned
