Shanghai Yetuo Constant Temperature Metal Bath is a laboratory equipment used to maintain a constant temperature, and its working principle involves heating and constant temperature control systems. The following is the working principle of a general constant temperature metal bath:
Heating element: The constant temperature metal bath contains a heating element, usually an electric heating element, similar to the element used in electric kettles. This heating element is responsible for providing heat to increase the temperature in the metal bath.
Temperature sensor: Metal baths are equipped with temperature sensors, usually sensors or thermocouples. The sensor measures the temperature of the liquid and sends feedback signals to the temperature control system.
Temperature control system: The temperature control system receives signals from temperature sensors and adjusts the power of heating elements based on the set temperature value. In this way, the system can maintain the temperature in the metal bath fluctuating around the predetermined target temperature.
Insulation layer: Metal baths usually also include an insulation layer to reduce temperature changes, improve stability, and reduce energy waste.
Circulation system (optional): Some constant temperature metal baths may be equipped with a circulation system to achieve uniform circulation of liquid in the bath, ensuring uniform temperature distribution throughout the bath.
The working process is as follows:
When the set temperature is higher than the current temperature, the temperature control system increases the power of the electric heating element to raise the temperature of the metal bath.
When the temperature approaches the set value, the control system gradually reduces the power of the electric heating element to avoid overheating.
If the temperature is lower than the set value, the system will increase power to maintain temperature stability.
This closed-loop control system enables the metal bath to maintain a very stable temperature within a set temperature range. Thermostatic metal baths are commonly used in the fields of chemistry, biology, and analytical chemistry where experiments need to be conducted at specific temperatures.
