Utility model content

In view of the fact that the existing deviation indication improvement device often makes its pointer deviate due to vibration or external interference, resulting in a decrease in the accuracy of temperature control, and the existing temperature controller contains a large number of sensor elements, amplifier circuits and Transformers, etc., are very heavy when assembled, so there is room for improvement. Therefore, the purpose of this utility model is to provide an improved device for deviation indication, which uses LED and seven-segment display to replace the existing pointer to display temperature changes. Therefore, the accuracy of temperature control is greatly improved, and circuits such as sensor components, amplifier circuits, and transformers are integrated into the IC, so that the cost and overall weight can be reduced.

In order to achieve the above purpose, the utility model provides an improved device for deviation indication, which includes: a housing, a panel and a control circuit, the housing is provided with several input/output contacts; the panel is connected to the housing integrated, and the panel has several display units and several control units, and the panel is combined with a display circuit, the display circuit is connected to the display unit; the control circuit includes a detection circuit, and the control circuit is controlled In the control unit, the control circuit is connected to the display circuit and the input/output contact, and the control circuit is arranged in the casing; thus, an improved device for deviation indication is formed.

By replacing traditional pointers with LEDs and seven-segment displays, and integrating sensor components, amplifier circuits, and transformers into the IC, temperature control accuracy can be reduced and weight can be greatly reduced.
