A specialized research and development facility required an ultra-precise environmental conditioning setup to establish and maintain strict temperature and relative humidity setpoints within a controlled test chamber. The operational environment demanded precise humidity generation—proportioning a dry air stream with a wet vapor stream generated by bubbling through a water vessel—alongside active thermal management via an industrial chiller to achieve target environmental conditions without condensation or drift.
Problem Statement
Non-linear Vapor Saturation
Thermal-Humidity Coupling
Solution Overview
High-accuracy humidity sensors
PID-based control algorithm
Controlled humidification / dehumidification units
Continuous monitoring and regulation of relative humidity
Key Features Delivered
Dual-MFC Humidity Generation
Employs two industrial-grade Mass Flow Controllers to route gas through dry and water-bubbler paths, precisely blending streams to achieve target relative humidity setpoints.
High-Precision Sensor & MCU Feedback Loop
ontinuously senses chamber temperature and humidity via an industrial probe array, providing real-time telemetry to an ARM Cortex MCU for PID loop updates.
Active Chiller Thermal Management
Directly controls a precision chiller unit in sync with the temperature PID loop to maintain exact thermal setpoints within the chamber environment.
