A high level of safety combined with enhanced productivity follows the company’s smart safety approach to increase plant availability. Heartbeat Technology creates the data basis for predictive maintenance and allows the instruments’ functionality to be verified without process interruption. Many industries are struggling with attrition, personnel turnover, and training new hires, and major plant additions are often performed by service providers who may not have a thorough knowledge of the equipment and systems on site. The amount of safety-related equipment continues to grow in many industries, and with it the number of costly required proof tests for maintaining safety integrity level (SIL).
