As the name suggests, a constant temperature tank is a tank that can provide a constant temperature. It can be divided into constant temperature air (usually called incubator) and constant temperature liquid (usually called incubator). According to the temperature range of constant temperature liquid, it is divided into low temperature incubator (usually -40 ° c ~ 100 ° c), constant temperature tank (usually room temperature ~ 300 ° c). Because the liquid medium above 100 °C cannot use water and oil, it is commonly known as oil tank. The constant temperature water tank has various names such as constant temperature oil tank, constant temperature water bath, constant temperature water tank, constant temperature circulator, electric constant temperature water bath, etc. With the help of the controller, a relatively standard temperature can be maintained to achieve the purpose of the experiment. Let's take a look at the heating and temperature control technology of the thermostatic bath.

As we all know, the main function of the thermostatic bath is to maintain the temperature. Thermostatic baths also have a technology called heating and temperature control. The temperature control of the liquid in the incubator is very strict. The general temperature control accuracy can reach 0.1 ℃, and sometimes it can even reach the unimaginable 0.01 ℃ temperature control accuracy. Temperature control of a thermostatic bath can be appreciated and questioned. Next I'll show you how it does it. If you want to control the temperature in the constant temperature tank to the temperature required by the equipment, the principle of resistance wire heating and compressor cooling is commonly used, coupled with the PID microcomputer to automatically fine-tune the temperature to achieve the purpose of temperature control.

The commonly used method is to use resistance wire for heating and compressor refrigeration, supplemented by PID microcomputer self-tuning temperature to control the management method, and to stabilize the temperature of the thermostatic bath at the set temperature required by the study.

The thermostatic bath is generally equipped with high-stable platinum resistance PRT or other temperature sensors, which respectively realize the temperature control and automatic protection of the thermostatic tank. The controller employs a special noise suppression circuit capable of detecting small resistance changes required for a highly stable constant temperature bath. Using an AC bridge to measure temperature to reduce thermal potential Custom high-precision low temperature coefficient resistors ensure short- and long-term stability of the temperature set point.

Advanced filtering technology overcomes power noise interference, stray electromagnetic interference and radio interference. The invention controls the power supply of the heater of the constant temperature box through the proportional integral control function, and almost eliminates the influence of overshoot through precise factory debugging, so that the constant temperature box can quickly reach its temperature stability after reaching the temperature set point. A key factor in the excellent performance of the bath is our hot port technology. In the invention, the cooling spiral tube and the heater are installed on the side of the stainless steel tube of the constant temperature tank in a sandwich shape, and the bottom of the steel tube becomes the heat exchange port where most of the heat enters and leaves the constant temperature tank.

The above is the heating and temperature control technology of the constant temperature tank. If you want to know more, you can contact us at any time! Our company has many years of experience and is looking forward to your joining.
