IIIBLD series temperature shock test chamber/thermal shock test chamber/environmental stress screening ESS test chambercontrol system
Control device for high and low temperature impact test chamber: The human-machine interface adopts a color large screen (5.7 inches) liquidCrystal touch display screen, control interface adopts full Chinese display, can set test parameters, curves, and total operating timeThe total operating time of the interval and section, the working status and time of the heater, etc. The development of control programsUsing human-machine dialogue, the interface is user-friendly, and automatic operation of the refrigeration machine can be achieved by simply setting the temperatureCan.

The control system uses an intelligent control software system, which has automatic combination of subsystems such as cooling and heatingThe working conditions ensure that the entire temperature range is maintainedHigh precision control, while achieving the goal of energy conservation and consumption reduction, with a complete detection device that can automatically perform

Detailed fault display and alarm, such as during testingWhen an abnormality occurs in the box, the controller displays the fault status in Chinese characters. Simultaneously possessing historical data table trendsStorage function for potential maps and historical fault records.Equipped with a communication interface, it can be directly operated by connecting to a computer.

Operation mode: Program running, constant running, timed start stop.
Temperature measurement: Pt100 platinum resistance temperature sensor.
