APCS Signal Conditioning

APCS Signal Conditioning

Since commencing operations in 1982 APCS has become the leading Australian designer, manufacturer and supplier of reliable signal conditioning modules that have been installed across a wide range of applications including processing operations, factories, transport, building automation, mining, power generation, marine, research, environmental and primary production. All APCS products are designed and manufactured to the highest quality standards at Ness Corporation to ensure they meet the often demanding conditions expected from Australian and global customers. APCS has built a reputation for quality manufacture and prompt delivery of its products.

Many APCS products are stocked as standard products, and others can be tailored to meet a customer’s requirements based on our expertise in the field of signal conversion, isolation, amplification, splitting, and sensor monitoring.



The SL Series signal conditioning range is the next generation of isolators, splitters and transmitters now easier to use, smarter and simpler to install than ever.
