Pressure switches (for example, a “normally open contact”), are often used for the monitoring and control of safety functions in order to signal any over or underpressure, and thus to prevent any damage to the machinery or the system. Switches with the “normally …
Electronic and mechanical switches are used for monitoring critical limit values and therefore usually fulfil a safety function. To meet this safety function, switches offer two alternative switching functions, the “hysteresis” and the “window” functions. In …
Modern electronic switches often offer a variety of different adjustable switching functions, such as the so-called “window”. When one talks of the “window” switching function, it means the monitoring of a defined measuring range (for example, for the …
The hysteresis switching function is generally included for all switch variants, whether mechanical or electronic, and whether for the parameter of pressure, temperature, level or flow. Hysteresis is generally understood to be the difference between the switch point …
As soon as a preset pressure is reached, an electronic pressure switch opens or closes a corresponding switch contact. There are various designs of electronic pressure switches which are used in a multitude of industrial and technical processes. Particularly in machine …
