Trafag MECHANICAL PRESSURE SWITCHES (PRESSOSTATS)
The mechanical pressure switches from Trafag are outstanding for their compact design and high-precision micro-mechanics specially developed and manufactured by Trafag itself. These switches can be installed in any position and need no electric power, making them particularly versatile in application and fully site-independent.
Product programe
The following information provides an initial programme overview. The individual product features are not freely combinable with one another. Further information can be obtained by consulting Trafag product catalogues and data sheets.
Piston
For hydraulic applications with frequent switching and abrupt pressure changes.Metal bellows
For fine control of pressure in liquid, vapor, and gaseous media.Membrane
For the measurement of liquid, vapor, and gaseous media in applications with high switching frequency, abrupt pressure changes and where a high level of overpressure safety is required.Housings
Aluminum housings, some epoxy coated, seawater resistant. With or without vision panel for switchpoint indicator.
