GDJS-225C

Temperature Humidity Cyclic Chamber

Introduction

 The product is suitable for the investigation of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, its moisture resistance, and can also be used as an adaptability test for storage, transportation and use in high-low temperature environments.

Cabinet structure

1. The whole box adopts an integral structure.

2. The inner side of the box is made of 1.0mm SUS304B stainless steel plate, and the outer side is sprayed with 1.0mm cold-rolled steel plateThe warm material is made of ultra-fine glass insulation foam.

3. The door seal is made of double-layer silicone rubber sealing material.

4. The observation window is multi-layer conductive film tempered insulating glass, and the size is 250×260mm to prevent low temperatureThe glass is frosted, surrounded by a built-in special heating wire, and illuminated by a light to provide illumination for observation.

5. There is a φ50mm test hole with a plug on the side of the box, and the plug material is silicone rubber with low foaming, which is durableHigh-low temperature, both thermal insulation effect.

6. An air conditioning cabinet is arranged at the back of the box studio, and evaporators, electric heaters, andHumidifiers, fans, fan volutes and other equipment.

7. The temperature sensor is placed at the air outlet.

8. The air supply mode in the Test Chamber is the upper air supply and lower return air mode.

Heating and humidification systems

1. The heater adopts porcelain frame nickel-chromium wire electric heater, which has low thermal inertia and long life. The controllable pulse duty cycle PID signal is output by the instrument, which is controlled by a solid-state relay, and the control is stable and reliable.

2. Steam boiler electric heating humidification method, armored electric heating tube, PID control mode, using non-contact periodic pulse widening SSR (solid state relay) control, equipped with water level control device, heater anti-dry burning device.

Control system

1. Temperature controller: LCD touch screen temperature and humidity controller

2. Sensor: PT100 temperature sensor.

3. The control heating output is triggered by solid-state relay zero-crossing to reduce noise, reduce pollution, facilitate maintenance, and improve control accuracy.

4. Safety protection measures should be set up in the control system, including: phase loss protection, phase sequence error protection, phase Voltage uneven protection, fan overload protection, over-temperature power-off protection, leakage and other protection.

5. The control system is equipped with a user-friendly operation panel, which is located in the upper left part of the Test Chamber, and is equipped with power supply, lighting, operation buttons for various functions and fault indicators.

6. In addition to the main controller in the system, an independent over-temperature protector is also set up, even if the main controller fails, the over-temperature protector can reliably disconnect the heating power supply to protect the safety of equipment and samples.

7. There is an interlock device in the electrical control system, and the heating and humidification system cannot be started when the circulating fan is not started or overloaded.
