Description
These high-quality mechanical pressure switches have been developed especially for safety-critical applications. The great advantage of mechanical pressure switches is that no supply voltage is required for the switching process.
The switches are traced by quality assurance software at every step of production and subsequently are 100 % tested.
The model PXS pressure switch can be installed in measurement environments with limited space due to its compactness. The robust switch enclosure from stainless steel 316 can withstand the rough and corrosive operating conditions. Operates in the process industry with working ranges of up to 1,000 bar.
The pressure switch is fitted with micro switches, which make it possible to switch an electrical load of up to AC 250 V, 5 A directly within a repeatability of 1 % of the set point.
The appropriate variant for the contact version and the electrical connection can be selected depending on the application. For example: hermetically sealed micro switches are suitable for corrosive ambient conditions and DPDT contact versions for two separate circuits.
A Belleville spring provides for the simultaneous triggering of the DPDT contact and, through the snap-action behaviour, increases the stability and vibration resistance.
The pressure switch is optionally available in a SIL-2 qualified or a SIL-3 qualified version for safety applications.
