Heating system

Continuous PID control, using AC contactor as the heating actuator, safe and reliable, with a separate overtemperature protection system.

Fan system

In order to ensure a higher uniformity index, the test chamber is provided with an internal circulation air supply system; In the interlayer of the air duct at one end of the studio, heaters, refrigeration evaporator, blades and other devices are distributed; Use the fan to circulate the air in the box, when the fan rotates at a high speed, the air in the studio is inhaled from the lower part of the air duct, and blown out from the upper part of the air duct after heating and cooling, and the air after heat exchange with the test products in the studio is inhaled into the air duct, repeated circulation, so as to meet the temperature setting requirements.

Control Sytem

Control system composition:

Temperature measurement: Pt100 platinum resistance;

Humidity measurement: Pt100 platinum resistance dry-wet bulb method;

Control device: touch screen programmable temperature and humidity controller TEMI850. Can display setting parameters, time, heater, humidifier and other work at the same time with automatic test operation and PID parameter self-setting function. The automatic operation of refrigerator can be realized only by setting the temperature. The control system uses intelligent control software system, with automatic combined heating, humidification and other sub-system working conditions, so as to ensure high precision control in the whole range of temperature and humidity, to achieve the purpose of energy saving and consumption reduction. Perfect detection device can automatically carry out detailed fault display, alarm, such as when the test chamber abnormal, the controller automatically display fault state.

Screen display: set temperature and humidity; Measured temperature and humidity;

Setting accuracy: 1℃

Operation mode: constant operation;

Other main low-voltage electrical components are famous brand products, such as Schneider AC contactor, thermal overload relay, Omron small relay, Delixi circuit breaker, Wan Fanyi water level float switch, etc.
