How does the high and low temperature test chamber complete the temperature control?

The high and low temperature test chamber is a product that is placed in regular temperature and humidity to study the high temperature resistance, low temperature resistance and humidity resistance of the product, and has the functions of heating, cooling, humidifying and dehumidifying. Therefore, the experimental box has a wide temperature control scale. This article aims to understand how to control the temperature of the high and low temperature test chamber and ensure the temperature control is completed to explain how it completes the temperature control and then obtains the experimental results. :

First, the temperature control of the high and low temperature experiment box

1, temperature sensor:

PT100

Platinum resistance sensor with high precision;

2. The temperature control output power is calculated by the microcomputer to achieve high precision and high efficiency power consumption;

3, temperature control selection

PID

+

SSR

The system operates in harmony with the channel. Heat balance temperature adjustment method;

4. The return air outlet has automatic defrost equipment.

Second, the raw materials of high and low temperature experimental box

1, the box body gallbladder: use high-grade

(SUS304)

Stainless steel plate

2, the box shell: excellent selection

A3

The steel plate CNC machine tool is formed and molded, and the outer surface of the outer casing is sprayed and treated, which is more clean and beautiful.

3. High-density glass fiber cotton is used as insulation material.

+

Polyurethane rigid foam, insulation cotton thickness is

100mm/120mm

.

4, survey window: the use of multi-layer hollow tempered glass, built-in lighting, the inner glued sheet type conductive film heating defrosting clearly investigate the experimental process;

5, temperature cycle system: the use of temperature-resistant low-noise air conditioning motor, multi-leaf centrifugal wind wheel;

6. Between the door and the box: Double-layer high temperature resistant and high-strength sealing strip is selected to ensure the sealing of the test area.

After the above two aspects of the temperature control of the high and low temperature test chamber and the raw materials for ensuring the temperature control, I believe that we have a deeper understanding of the experimental temperature control, which will bring us very accurate operation and protection. Great assistance.
