Pressure Switches for Medical Applications<\/h1>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tIn medical systems, pressure monitoring is not a convenience feature but part of the safety technology. Whether for breathing air supply, sterilization processes, or organ transport: stable, precisely defined pressure conditions are prerequisites for patient safety and validated processes. Our pressure switches offer low setpoint drift and long-term functional reliability, even with oxygen, saturated steam, or elevated temperature and pressure conditions. \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

Hospital \u2013 Monitoring Medical Breathing Air<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tMedical breathing air is generated centrally in hospitals and flows through a piping system to the supply units. Ventilators and other systems only operate above a defined minimum pressure. Our pressure switch monitors it directly in the unit and immediately reports a drop to the control system or alarm chain. Because alarm systems rely on precise setpoints, repeatability is particularly important here, in the setting range of 1 to 16 bar. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    \n\t\t\t\t\t\t\t\t\tA high-pressure autoclave sterilizes instruments with saturated steam, which only works at a precisely defined ratio of pressure and temperature. In practice, our pressure switch often enables the cycle: only when the required pressure is present does the validated sterilization start. It can also lock the door as long as residual pressure remains in the vessel. Stainless steel housing, stainless steel or EPDM membrane, and low drift over many cycles ensure it performs this function with equal reliability for years. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

      The media used place very different demands on the pressure switch. With oxygen, suitable materials and appropriately clean execution are particularly critical. Medical breathing air places different demands on the media-wetted components, while with saturated steam, high temperatures and recurring thermal loads must also be considered. Therefore, we do not view media compatibility in isolation, but always together with pressure, temperature, and the specific installation situation. <\/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

      A mechanical pressure switch converts a defined pressure state directly into an electrical switching signal. No additional electronic pressure evaluation is required. This can be particularly advantageous for clearly defined monitoring, enable, or alarm functions. However, it is crucial that the switch point, switch direction, and electrical design are matched to the respective function\u2014for example, when monitoring a breathing air supply, pressure enabling of an autoclave, or a mobile medical supply unit. <\/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 operating pressure, desired switch point, and switch direction, the medium, temperature range, and specific function in the system are particularly important. This is supplemented by pressure connection, electrical load, connection type, and installation situation. For mobile applications, mechanical loads and cable routing must also be considered; with oxygen or saturated steam, media compatibility and material selection are particularly important. On this basis, we can determine the appropriate design and configuration for 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<\/div>\n\t\t\t\t\t
