Working Principle of Temperature and Humidity Calibration Chambers
Temperature and humidity calibration chambers operate through a system of sensors, heating/cooling elements, and humidification/dehumidification units. These components work in tandem to create a controlled environment with precise temperature and humidity settings, maintained through a feedback loop system.
Temperature Control: The chamber regulates temperature using heating elements and cooling systems, ensuring the interior temperature matches the desired setpoint. Temperature ranges in these chambers can vary widely, from sub-zero temperatures (e.g., -40°C) to high temperatures (up to +150°C), depending on the specific application.
Humidity Control: Humidity is controlled through humidifiers (often steam or ultrasonic) and dehumidifiers (either cooling-based or moisture-absorbing materials). The relative humidity (RH) range typically extends from 10% to 98%, offering flexible calibration options for various environmental conditions.
Feedback Control System: A network of temperature and humidity sensors continuously monitors the chamber's internal conditions, sending real-time data to the control system. This feedback allows the system to make adjustments and maintain stable, consistent environmental conditions.
