HAESL - incremental encoders help optimise the fuel efficiency of aero-engines

How fuel efficient is a commercial airliner? The honeycomb seal-ring has been proven to optimise the fuel efficiency of aero-engines, but the measurement of these seals present difficult engineering challenges. Now, HAESL has solved this challenge by incorporating Renishaw's TONiC incremental linear and rotary (angle) encoders within its new optical Seal Ring Measurement System (SRMS).

Renishaw encoders go under the 3DHISTECH microscope

3DHISTECH designs and manufactures one of the world's fastest and highest-capacity autonomous panoramic digital slide scanners - the P1000. It is a highly accurate scanning microscope that enables large pathology labs to capture ultra-high resolution images of medical samples. Renishaw's VIONiC™ and LA11 encoders enable the P1000 to operate at higher speeds than competing products in an accurate and repeatable way.

Application notes

Reducing air purge usage with FORTiS™ encoders, achieving energy saving up to 91%

Machine users adopting a smart approach to air purge with FORTiS absolute enclosed encoders can significantly reduce their attributable CO2e emissions, and lower electricity costs. FORTiS' unique DuraSeal™ lip seals allow many users to employ a “low flow” air purge philosophy to provide all the reliability benefits of air purge but with reduced compressed air consumption.
