1.1 Intended use
The pressure switch may only be used in such applications as are within its technical performance limits, in particular
with regard to its material resistance limit, leakage rate limits and permissible temperature and pressure limits.
It is the sole responsibility of the manufacturer or operator of a machine or plant to ensure the suitability of the pressure
switch, and its media resistance, within the application through proper choice of materials and maintenance cycles. For
performance limits, see chapter 9 "Specifications".
Special versions for oil and grease-free applications, as well as for use with oxygen (dangerous fluid in accordance
with Directive 2014/68/EU Article 13, Regulation (EC) No. 1272/2008, or GHS 1)), are available on request.
The mounting, dismounting, installation, parameterisation and maintenance of the pressure switch in industrial
environments absolutely requires suitably skilled personnel in accordance with chapter 3.2 "Personnel qualification".
The instrument has been designed and built solely for the intended use described here, and may only be used
accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
