The directive 2006/42/EC on machinery, which will come into effect end of 2009, will increase the requirements for machine builders in many areas. The pressure sensors type P3375 from tecsis fulfil SIL-2 according to IEC 61508 and Category 3, Performance Level d, according to ISO 13849-1. Therefore they can be used for mobile hydraulics applications to meet the requirements of the new directive on machinery. Internal redundancy of the pressure measurement and two independent outputs, which can be evaluated in a subsequent controller, are used for safety reasons. The pressure sensors are available in a big variety of measuring ranges from 0...60 up to 0...1,000 bar.
