Measurement and control system

1) This device adopts the Japanese "Fuji" temperature controller, with a temperature control accuracy of ± 0.1 ℃ (display range)

2) Equipped with PID self-tuning function, fuzzy control function, multi-point alarm function, parameter shielding function, user adjustment function, slope/insulation function

3) The sensor is a Pt100 platinum resistance sensor with high accuracy and precision

refrigeration system

1) Adopting the French "Taikang" fully enclosed refrigeration compressor unit, each unit is monitored item by item through the European "Taikang" computer network and has anti-counterfeiting codes, which can be searched online through computers

2) Refrigeration compressor: To ensure the cooling rate and achieve the lowest temperature requirements of the test chamber, its connecting container is an evaporative condenser. The function of the evaporative condenser is to use the low-pressure cycle evaporator as the high-pressure cycle condenser

3) Refrigeration auxiliary components: air-cooled coil condenser, finned multi-stage evaporator. The main refrigeration accessories and control components are imported, such as the Danfoss thermal expansion valve from the United States and the Aego drying filter from the United States, and the Castello solenoid valve from Italy;

4) The design of refrigeration systems should incorporate energy regulation technology, which is an effective way to ensure that the energy consumption and cooling capacity of the refrigeration system can be effectively adjusted while the refrigeration unit is operating normally, reducing the operating costs and failure rates of the refrigeration system to a more economical state.

5) Refrigerant: uses refrigerant R502 (low-pressure cycle)

6) Cooling method: air cooling
