Safe radar sensors are used where optoelectronic sensors reach their limits: rugged environments, such as outdoors or in material processing for example, can be monitored safely using PSENradar. That’s because radar technology (FMCW: frequency modulated continuous wave) ensures high availability even where there are external influences such as dust, dirt, rain, light, sparks or vibrations. http://www.pilz.com
The safe radar sensor PSENradar, in conjunction with the configurable small controller PNOZmulti 2, offers a safe, complete solution for protection zone monitoring – including conformity assessment for the plant or machine. The underlying volumetric monitoring with a frequency of 24 – 24.25 GHz can be used up to SIL 2, PL d and Category 3, which is often a requirement in robot applications. The complete solution also has additional interfaces, such as Ethernet and Profisafe, so making it easy to use the safety radar sensor in retrofit applications. http://www.pilz.com
The appropriate protection zone can be defined for each sensor, based on the size of the area to be monitored. This depends on the positioning, installation height and inclination of the sensor. A warning zone can also be configured in addition to the protection zone. If a person violates the warning zone, this may be signalled by an optical signal, for example. This way, productivity of the plant can always be kept at a high level.
