There are several batch processes that need historical data, which makes the documentation of measured variables essential. Honeywell’s Circular Chart recorders offer a cost-effective way to maintain these records and help manufacturers optimize the data collection process. The recorders are microprocessor-based and can record a variety of process parameters such as temperature, humidity, pressure or flow from transmitters. These are ideal for high-performance applications requiring accuracy such as those used in dairy, textile and food machinery, industrial ovens, environmental chambers, pharmaceutical equipment, metalworking, industrial furnaces and farm machinery.
