Environmental Control Chamber for Automated Calibration Systems

Product Specifications

Technical details and manufacturing context for Environmental Control Chamber

Definition

The Environmental Control Chamber is a critical component of the Automated Industrial Calibration System that provides a precisely controlled testing environment. It creates and maintains specific temperature, humidity, and atmospheric conditions required for calibrating industrial instruments and sensors. This chamber ensures that calibration procedures are performed under consistent, repeatable environmental conditions, eliminating external variables that could affect measurement accuracy. It typically includes insulation, heating/cooling systems, humidity control, and monitoring sensors to maintain the desired parameters throughout the calibration process. The chamber is constructed with stainless steel interior (SUS304 per ASTM A240) and powder-coated exterior (SPCC per JIS G3141), with insulated panels and tempered glass viewing windows. Standard internal dimensions are 1000×800×800 mm (W×D×H), with custom sizes available. Temperature range is -40 to 85 °C, with stability of ±0.1 °C and uniformity of ±0.5 °C across the working space. Humidity range is 20–98 % RH (at 20–85 °C), with stability of ±1.0 % RH. Pressure range is 1.0–1.6 MPa, with control accuracy of ±0.01 MPa. Electrical supply is 380–415 V AC, 3-phase, 50/60 Hz (per IEC 60038), with power consumption of 5–8 kW. Ingress protection is IP54–IP65 (per IEC 60529). Weight ranges from 500–800 kg depending on configuration. The chamber interfaces with the main calibration controller to coordinate environmental stabilization with measurement procedures. All listed parameters are reference ranges; verify model-specific values with the manufacturer.

Working Principle

The chamber operates by using a closed-loop control system where environmental sensors continuously monitor internal conditions. When deviations from set parameters are detected, the control system activates heating elements, cooling systems, humidifiers, or dehumidifiers as needed. Insulated walls minimize external environmental influence, while air circulation systems ensure uniform conditions throughout the chamber volume. The system interfaces with the main calibration controller to coordinate environmental stabilization with measurement procedures.

Frequently Asked Questions

What is the standard internal dimension of the chamber?

The standard internal dimensions are 1000×800×800 mm (W×D×H). Custom sizes are available upon request, but you must confirm the exact dimensions with the manufacturer for your specific model.

What temperature range and stability can the chamber achieve?

The temperature range is -40 to 85 °C, with stability of ±0.1 °C at set point and uniformity of ±0.5 °C across the working space. Extended range options may be available; verify with the manufacturer.

What are the electrical supply requirements?

The chamber requires a 3-phase, 50/60 Hz electrical supply of 380–415 V AC, per IEC 60038. Power consumption is typically 5–8 kW depending on the operating point. Always confirm the electrical specifications with the manufacturer for your installation.

What ingress protection rating does the chamber have?

The chamber is available with ingress protection ratings from IP54 to IP65, per IEC 60529. The IP65 rating is suitable for dusty environments. Confirm the required rating with the manufacturer based on your application.
