In construction and environmental technology, machines operate under harsh external influences: constant vibration, dirt, temperature fluctuations, and high mechanical stress are the norm. A pressure switch that is to withstand these conditions needs more than just an accurate switch point; it must maintain it even when everything around it is shaking. This is precisely what our heavy-duty versions are built for. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\tA waste compactor compresses until the hydraulic pressure reaches its limit, typically at around 150 bar rising. Our pressure switch detects this point and shuts down before the hydraulics are overloaded. At the same time, the reproducible switch point ensures that every compaction cycle is consistent. It is designed with a vertical flange, is pressure-resistant, and is insensitive to vibration during continuous operation. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

      What characterizes a pressure switch for heavy-duty applications? <\/h3><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

      For us, heavy duty does not just mean “robust”. In such applications, several loads often act on the pressure switch simultaneously: high system pressures, strong vibrations and shocks, changing temperatures, dirt or moisture, and in some cases, a high number of switching cycles. The decisive factor is therefore the interplay of mechanical construction, suitable materials, secure electrical connection, and switching behavior that fits the respective application. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      How are pressure peaks and dynamic loads taken into account? <\/h3><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

      The set switch point is only one part of the design. Especially in hydraulic systems, significantly higher pressures can occur briefly than in normal operation. Such pressure peaks and rapid pressure changes must be taken into account when selecting the switch. Therefore, we distinguish between the actual operating or switching range and the maximum permissible pressure load of the respective series. For highly dynamic applications, we additionally consider how frequently and how quickly these loads occur. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      In addition to the operating pressure and the desired switch point, the maximum system pressure, possible pressure peaks, and the dynamics of the pressure curve are particularly important. Additionally, we require information on the medium, temperature, installation location, vibration and shock load, as well as the desired electrical interface. The expected switching frequency can also be decisive. On this basis, it can be assessed which series and version is suitable for the actual load. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t
