safety in the production process
monitoring melt & furnace during production
FIOScope® & FIOSens® – attentive and sensitive for higher safety in production
Our self developed high-end equipments are the perfect combination regarding safety issues in the production process as well as preserving the value of your facility. Perfectly tuned to one another, both systems make sure that you keep being perfectly well informed about what is going on inside your furnace. Thanks to internet-based remote maintenance you may get results anytime from anywhere around the world. Both, FIOScope ® and FIOSens ® will convince you of their exceptional performance and practical suitability. Our longstanding expertise, continuous improvement of our systems and the use of innovative technologies have made franke a sought-after partner in this special field.
FIOScope® The camera system
fluid free, patented and »Made in Germany«
Our fluid-free FIOScope ® gives you the possibility to check the burning process in your furnace chamber at any time and any place. Experience crystal clear images in true HD resolution – at temperatures up to 1500 °C and with a shock and vibration resistant design!
The modular design consists of the camera, exchangeable lenses and special filters. It guarantees the best possible visibility in any combustion chamber.
The view opening of the probes and the lenses are kept dust-free by oil-free flush air or shielding gas. For the use in aggressive or corrosive environments, several cooling jackets in special alloy and with special coating are available.
The adaption to different wall sizes is ensured by an appropriate selection of probes in combination with a corresponding peep hole by the refractory supplier.
FIOSens®
sensor monitoring system of the tank bottom
FIOSens ® finally makes it possible to monitor the bottom of your melting tank. Keep your temperatures under observation as well as the remaining lining thickness for an early detection of glass penetration into the lining. Installation is quick and simple. Assure yourself of our quality!
Monitoring of
- remaining lining thickness
- temperature
- glass penetration into the lining
Visualisation of
- remaining lining thickness as floor profile
- lining thickness as function over time
- trend curves of lining thickness
- temperature distribution in the bottom
- temperature curves as function over time
