The difference between high and low temperature test chamber and high and low temperature alternating test chamber control system

Control of high and low temperature alternating test chamber   Braking system

lThe temperature and humidity control instrument adopts (Korea) imported large screen screen, the screen operation is simple, the program editing is easy, no need to input the button, the screen directly touches the option;

l Accuracy: 0.1 ° C (display range);

l Resolution: ±0.1 °C;

l Temperature sensor: PT100 platinum resistance temperature measuring body;

l Control mode: heat balance temperature adjustment mode;

l Temperature and humidity control adopts P.I. D+S.SR system co-channel coordinated control;

l With automatic calculation function, the temperature and humidity change conditions can be corrected immediately, so that the temperature and humidity control is more precise and stable;

l The controller operation interface is available in Chinese and English, and the real-time running curve can be displayed on the screen;

l has 120 sets of programs, each group of 100 segments, each segment can cycle 999 steps of capacity, each time set zui large value of 99 hours and 59 minutes;

l After inputting the data and test conditions, the controller has a screen lock function to avoid human touch and stop;

l With RS-232 or RS-485 communication interface, you can design programs on the computer, monitor the test process and perform functions such as automatic switching, printing curve, data, etc.

l The controller has a screen automatic screen saver function to better protect the LCD screen during long-term operation (to make it last longer);

l The air vent of the test chamber has an automatic defrosting device (so that the water vapor generated during the test will not accumulate on the refrigeration evaporator, causing ice blockage).

High and low temperature test chamber control system

l Temperature control adopts imported RKC digital display touch button, P. I. D system co-channel coordinated control;

l Accuracy: 0.1 °C ( display range);

l Resolution: ±0.1 °C;

l Temperature sensor: PT100 platinum resistance tester;

l Control mode: heat balance temperature adjustment mode;

l With automatic calculation function, it can reduce the inconvenience caused by artificial setting.

The device temperature control part is controlled by intelligent high - precision digital display PID microcomputer control instrument, film type button , touch type setting, digital position and direct display, and temperature control output power are calculated by microcomputer to achieve high precision and high efficiency. Electricity efficiency.

The temperature control adopts P.I.D + S.S.R. The system co-channel coordinated control can improve the stability and life of the control components and interface. Having a P. I. D automatic calculation function, it can reduce the inconvenience caused when the manually set. When the device is running or set, an alert number will be provided if an error occurs.

The time controller of the device controls the time required for the test and is simple to operate. When the device reaches the set time, the test is automatically stopped and the temperature is automatically entered.
