Product Specifications

Technical details and manufacturing context for Humidity Control Module

Definition
The Humidity Control Module is an integral part of an Environmental Control System designed to precisely monitor, adjust, and stabilize the moisture content in the air of a defined space. It works in conjunction with other system components (like temperature controllers and air handlers) to create and maintain optimal environmental conditions required for specific industrial processes, product storage, or operational safety.
Working Principle
The module typically operates by using a humidity sensor to measure the current relative humidity (RH) in the environment. This data is processed by a controller. If the RH deviates from the setpoint, the controller activates an actuator. To increase humidity, it may trigger a humidifier (e.g., ultrasonic, steam). To decrease humidity, it may activate a dehumidifier (e.g., refrigerant-based, desiccant) or coordinate with the system's ventilation to introduce drier air. It continuously cycles to maintain the target humidity range.
Common Materials
Stainless Steel (housing), Polycarbonate (sensor cover), Electronic Components (PCB, sensors, relays)
Technical Parameters
  • Humidity Control Range; the span of relative humidity the module can effectively regulate (e.g., 20% to 80% RH). (% RH) Per Request
Components / BOM
  • Humidity Sensor
    Measures the current relative humidity in the environment and sends the signal to the controller.
    Material: Polymer/ceramic sensing element
  • Microcontroller/PLC Interface
    Processes sensor input, compares it to the setpoint, and executes the control logic to activate humidification or dehumidification outputs.
    Material: Silicon (integrated circuits)
  • Relay Output Board
    Provides switched electrical connections to control external devices like humidifier solenoids, dehumidifier compressors, or damper actuators.
    Material: FR4 PCB, copper traces, electromechanical relays
Engineering Reasoning
20-80% RH at 15-35°C ambient temperature, 0.5-10.0 m³/min airflow
Condensation formation at dew point differential <2.0°C, sensor saturation at >95% RH for >30 minutes
Design Rationale: Adsorption-desorption hysteresis in hygroscopic polymer sensors exceeding 3.0% RH deviation, Peltier element thermal stress at >50W/cm² heat flux density
Risk Mitigation (FMEA)
Trigger Capacitive humidity sensor dielectric breakdown at >5.0 kV/mm field strength
Mode: Humidity reading lock at 0% RH, PID controller saturation
Strategy: Multilayer ceramic capacitor with X7R dielectric (εr=2000) and 100μm electrode spacing
