    4 Observation and lighting

     

     

    The heating system

    Continuous PID control, the use of ac contactor as heating actuator, safe and reliable, has a separate overtemperature protection system

     

     

     

     

     

     

     

    Air duct system

    In order to guarantee high evenness index, test chamber is equipped with internal circulation air supply system; Duct sandwich at the end of the studio, the distribution of the heater, refrigeration evaporator, blades, etc; Use fan to make the air circulation in the oven, when fan at high speed, the studio in lower suction air duct, after heating, cooling, blow out from the upper air duct, the sample (s) in the studio and heat transfer within the air inhaled air duct again after repeated circulation, so as to achieve the temperature set requirements.

     

     

     

     

     

     

     

     

     

     

     

    Control system

    Temperature measuring: Pt100 platinum resistance

    Humidity measurements: Pt100 platinum resistance dry wet ball method

    Control unit: programmable digital temperature controllers and humidity controllers TEMI880. Can display set parameters, time, heater, humidifier and other working condition, and has run test at the same time and PID parameters self-tuning function. It takes only a set temperature can achieve the function of refrigerating machine to run automatically. Control system using intelligent control software system, has automatic combined cooling, heating, humidification, etc. The operation condition of the subsystem, so as to ensure the high precision control of temperature and humidity in the whole range, to achieve the purpose of saving energy and reducing consumption. Perfect detection device can automatically, according to the detailed fault alarm, such as when the chamber when an exception occurs, the controller automatically according to fault state.

    Screen display: set temperature and humidity; the measured temperature and humidity

    setting precision: 1

    operation modes: constant operation

    Other main low voltage electrical components adopt famous brand products, such as Schneider ac contactor, thermal overload relay, OMRON small intermediate relay, delixi circuit breaker, Taiwan and all appropriate water level float switch, etc
