control system 1. Temperature measurement: Pt100 platinum resistance. 2. Control device: The controller adopts imported programmable PLC and high-quality imported LCD color LCD touch screen dual-loop temperature control system, and its control display adopts imported color LCD touch screen (5.7-inch) control display. The controller adopts Chinese operation display interface. Display, display, set test parameters, curve, total running time, total running time of the segment, heater working status and calendar time. The control program is compiled by man-machine dialogue mode, and the interface is friendly. The automatic operation function of the refrigerator can be realized only by setting the temperature. High temperature aging room, hot and cold impact box, walk-in test room, constant temperature aging room The control system uses an intelligent control software system, which is equipped with automatic combined refrigeration, heating and other subsystems to ensure high-precision control over the entire temperature range, while achieving energy saving and consumption reduction. The perfect detection device can automatically perform Detailed fault display, alarm, such as when the test box is abnormal, the controller displays the fault status in Chinese kanji, and has the storage function of historical data table trend graph and historical fault record. The manufacturer provides a free upgrade of the control software system for two years. Optional R485 computer communication interface and computer upper and lower computer computer auxiliary control system device to realize continuous data transmission and remote control functions. Recorders can also be optionally used for experimental data recording. 3, system setting accuracy: temperature: 0.1 °C Time: 1min 4, running mode: program running or fixed value can be 5, the device has an independent working time tired timer. Safety protection measures 1. Safe and reliable grounding protection device 2, power supply undervoltage, phase loss protection 3, independent studio over temperature protection 4. Refrigerator overpressure, overload, oil pressure undervoltage protection; 5, heater short circuit, overload protection.
