Mechanical pressure measuring instruments with integrated alarm contacts offer two functionalities in a single unit. The task of the pressure measurement is achieved without the need for any external power supply and thus always provides a reliable on-site display. At …

What is meant by the “change-over” switching function with pressure switches?
Enrico Bossart | Know-howA pressure switch with the “change-over” switching function represents a special version of a pressure switch with two switching outputs acting oppositely to switch two circuits. A “change-over” closes one circuit and simultaneously opens a second circuit. Thus …
What is meant by the “normally open” switching function with pressure switches?
Enrico Bossart | Know-howPressure 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 …
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 …
