In the specification of the switch points of a float switch, misunderstandings always lead to unsuitable product designs. How one correctly specifies the switch point of a float switch will be explained here. The basic prerequisite for the correct specification …

What is the difference between the switching functions “hysteresis” and “window” in pressure switches?
| Enrico Bossart | Know-howElectronic 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 …
What is meant by the “window” switching function with electronic pressure switches?
| Enrico Bossart | Know-howModern 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 …
Connection diagram of PNP and NPN transistor outputs for electronic pressure switches
| Jürgen Reiser | GeneralManufacturers of electronic pressure switches often offer both PNP and NPN switching outputs. Here is a brief explanation how the two different outputs should be connected. In principle, both are bipolar transistors in which only the internal arrangement of the pn …
