Encoders for Oil and Gas Industry
The oil and gas industry, due to its specific environment, requires reliable coding solutions. The strict standards of the oil & gas industry must be applied to all products used, as applications can be offshore and onshore, in the Atlantic or in the Far North, often in very harsh environments (corrosive sea salt, low and high temperatures, shock and vibration, high humidity) and in hazardous areas. Encoders need to be reliable for many years, accurate and compliant with current standards.
Our encoders are designed to withstand the demanding conditions of the oil and gas industry, guaranteeing long-term reliability and accuracy. Contact us to find out how our solutions can support your operations in the oil & gas industry.
