1, visual inspection and judgment (1) Judging: The XDl (red) and XD2 (green) indicators on the control panel indicate the heat preservation and heating status of the high temperature furnace (ie power off and power on). Close K2 under normal....
1. Loosen the screw at the top of the thermostat with a small Phillips screwdriver and then remove the outer casing. Then use the screws provided on the bottom plate to fix the place you want to fix and then fasten the temperature controller....
The temperature controller circuit uses LED light-emitting diodes to display the temperature in sections. When the temperature reaches the highest temperature displayed, the heating device automatically stops working. The temperature contro....
The thermostat controller consists of the thermistor Rt1, Rt2, NE555 time base circuit, temperature range adjustment resistors RP1, RP2 and the control actuator. The circuit is shown in Figure 1 (click here to download the schematic). Rt1 a....
In production and scientific research, electric oven thermostats are widely used, and temperature measurement and control accuracy are also required. In the application, when the thermostat controller cuts off the electric power of the elect....
