The high and low temperature test chamber is a critical tool used to evaluate a product's ability to withstand extreme temperatures and humidity conditions. By subjecting the product to controlled environments, this device tests its resistance to heat, cold, and moisture, as well as its capacity for heating, cooling, humidifying, and dehumidifying. As a result, the test chamber is designed with a wide temperature control range, making it essential in various industries such as electronics, automotive, and materials science.
This article aims to explain how the high and low temperature test chamber achieves precise temperature control, ensuring accurate experimental results. Understanding the mechanisms behind temperature regulation can greatly enhance the efficiency and reliability of testing procedures.
First, let’s take a closer look at the temperature control system:
1. **Temperature Sensor**: The chamber is equipped with a PT100 platinum resistance sensor, known for its high accuracy and stability over a wide temperature range. This ensures that temperature readings are reliable and consistent.
2. **Control Output**: A microcomputer calculates the required power output for temperature adjustment. This intelligent system helps achieve high precision while optimizing energy consumption, making the process both efficient and cost-effective.
3. **PID+SSR Control System**: The temperature regulation uses a PID (Proportional-Integral-Derivative) control combined with Solid State Relays (SSR). This system allows for smooth and stable temperature adjustments, maintaining balance between heating and cooling cycles.
4. **Defrost Function**: The return air outlet includes an automatic defrost mechanism, preventing ice buildup and ensuring continuous operation without manual intervention.
Next, let’s explore the materials used in constructing the high and low temperature test chamber:
1. **Box Body**: The internal structure is made from advanced SUS304 stainless steel, which offers excellent corrosion resistance and durability, even under harsh conditions.
2. **Outer Shell**: The outer casing is crafted from high-quality A3 steel, processed using CNC machines for precision. The exterior is finished with a plastic coating, giving it a clean and professional appearance.
3. **Insulation Material**: The insulation layer consists of high-density glass fiber cotton combined with polyurethane rigid foam. With a thickness of 100mm or 120mm, it provides excellent thermal resistance and minimizes energy loss.
4. **Observation Window**: The chamber features a multi-layer hollow tempered glass window with built-in lighting. An inner conductive film heating element ensures clear visibility during testing, even in low-temperature environments.
5. **Air Circulation System**: A temperature-resistant, low-noise air conditioning motor drives a multi-leaf centrifugal fan, ensuring uniform temperature distribution throughout the chamber.
6. **Door Sealing**: The door is sealed with a double-layer high-temperature resistant and high-strength sealing strip, ensuring airtight performance and maintaining stable internal conditions.
By combining advanced temperature control systems with high-quality materials, the high and low temperature test chamber delivers reliable and accurate performance. This understanding not only enhances operational efficiency but also supports better maintenance and troubleshooting in the long run. Whether you're conducting research or quality assurance tests, having a clear grasp of how the chamber works can significantly improve your overall experience and outcomes.
The temporary fence, is also called portable fence, crowd control barrier. It is very convenient both in installaion and movement. The temporary fence and barriers is widely used in construction sites, tempory protetion, major sports events or activities and crowd control. Our steel barriers are design for help you keep control of your crowds at your event. They are made of heavy-duty steel with secure interlocking hooks. The pedestrian control barriers are commonly used at many public events and parking area. They are frequently visible at sporting events, parades, outdoor festivals, works, roads, streets, car parks, shopping centres, and restaurants. Event organizers, venue managers, and security personnel use barricades as part of their crowd management planning.
Main markets
