Wireless Feldbus-Lösungen


Would you like to determine the volume flow of your systems precisely, simply and reliably? Use a standard measuring device (e.g. folding rule) to determine the cross-section of your duct. Enter this value into our RHEASGARD® flow monitor and mount it on the duct as usual to measure the flow velocity. The device simply and automatically determines the current volume flow.

Christmas greetings


Bringing joy to others. This is also the meaning of Christmas for us at S+S. This year, we have once again decided to forego Christmas presents for our customers and business partners and instead support regional projects.

For example, we have decided to sponsor the regional sports club TV21 Büchenbach. The children in the athletics department are now looking forward to new training shirts.
We also support the children's aid project "Sternstunden e.V." organised by Bayerischer Rundfunk. 

We would like to thank you for the good and trusting cooperation during this challenging time and will of course be at your side again next year as a strong supplier and partner.

showcase sensor


Humidity and temperature sensor for installation in ceilings, display cabinets or showcases

The calibratable HYGRASGARD® VFF/VFTF cabinet sensor measures the relative humidity and temperature of the air and is available with or without a display. The measured values are converted into a 0-10V or 4...20 mA standard signal. The measuring element is located in a stainless steel probe and is barely visible thanks to its low height of approx. 2.5 mm.

Donation instead of presents!


Donation instead of presents!  

Due to the diffucult situation of many people, we have decided not to send Christmas presents to our customers and business partners. Instead, we support local aid organisations for people in need: 

"Freude für Alle" (Joy for All) – a Christmas campaign of the Nürnberger Nachrichten
For 50 years now, the campaign has been supporting people who are socially marginalised and in need - whether due to illness, a disability, unemployment, due to low pension entitlements or for other reasons. A major focus is on children, who suffer particularly from poverty.

"Tafel Nürnberger Land e.V." – Food donations for people in need  
According to the motto "everyone gives what they can", more than 100 small and large companies are involved in the Tafel Nürnberger Land. They collect "surplus", but qualitatively impeccable, saleable food. Direct and uncomplicated help for people who are on the edge of the subsistence level.
