What is the cam for a cam?

The cam timer is a mechanical device powered by electricity that controls a number of switches by moving a rotating wheel or cam. These timers were used extensively before the invention of digital programmable timers. The cams of the cams are useful to control the machine or process in a number of steps that occur one by one.

Production control in industrial systems was a common use of a cam timer within the 20th century. The timer was connected to mechanical switches that sent control signals to valves or pumps. Complex systems were difficult to control with cam timers due to problems with inaccuracy. In addition, a change in any operating parameter required to divide the timer and the changing cams. The moving button for washing turned the camera behind it and the desired wash was aligned with the cam switch. The first machines had no flexibility for different washing or watermark, so the real time of washing was affected. Later machines added a load switchThe water that switched off the cam for the cam until the mat was filled, resulting in a more accurate wash time. Cam timers were regularly used in sales machines. Inserting money into the machine activates the timer that controls the car. Car timers may not function as a standard clock timer, but were used to ensure sequential or serial operations at a set time.

cam timers can act as clock timers, with a number of cams installed to provide functions at regular times. Water treatment systems also use them in some designs to activate reverse or water softening. The cam timer can act as a clock for a regular control operation, such as reinforcing the filter every day. Activation of timer by separate control is also possible, for example, the use of the total WEATER ATER to start regenerationwater.

digital or digital logic controllers have replaced cam timers for many applications since the age of 80. Electronic controllers are more accurate for timing functions. Programming change in the controller can be as simple as accessing the computer screen, rather than dismantling the timer to change CAM. Logical controllers can be programmed with a number of control functions rather than a single timer function. This may result in lower costs by requiring fewer drivers.
