Low Temperature Circulator BCLT-204 Applications Refrigerated and Heating Circulator, thanks to its features such as highly precise and stable temperature control and fast heating and cooling, has been widely used in precise and thermostatic control equipment in sectors such as petroleum, physics, chemical industry, pharmacy, and environmental protection. -
Page 4: Working Principle
Low Temperature Circulator BCLT-204 Working Principle 1. Principle block diagram 2. Principle The circulator displays with a high-brightness LCD screen and measures temperature with a high-precision sensor. It feedbacks the measured temperature to CPU in a real-time manner, and then the fuzzy PID calculates a set of appropriate duty ratio to control heating equipment, while the mixing device is constantly circulating water in the bath so that water temperature in the bath becomes more even. -
