The TECA1-XV-XV-D Peltier controller is designed to drive thermal electric coolers ( TECs ), and its parameters can be customized. This Peltier controller has a compact size, 25.6mm*20mm*7.5mm (see Figure 1), so that it is very easy and convenient to use, carry and store. In addition, the Peltier controller has high reliability, high stability and some other advantages. Figure 1. The TECA1-XV-XV-D Peltier controller For TECA1-XV-XV-D, the first X stands for the maximum input voltage, and the sec...(more)
Continued from last article. In actual liquid level measurement, the temperatures of the water and air are often not the same. When the air temperature is low and the water temperature is high, we cant judge NTC thermistor is in the water or air according to the voltage. However, if we know a temperature point and also the voltages of the air and the water at this temperature, then we can judge the NTC thermistor is in the air or in the water. That is to say, the liquid level and the temperature...(more)
Continued from last article. We are introducing liquid level measurement for NTC thermistor. In the water and air of the same temperature, and under the same electrical condition, a constant current is provided to NTC thermistor, and make the thermistor produce self-heat. The voltage of NTC thermistor is relatively stable after heat balance. Then put it into the water, the voltage of NTC thermistor rises. Thats because when NTC thermistor enters into the water, the temperature falls, resulting i...(more)
NTC thermistors are widely used in temperature measurement and control system. ATI provides a complete series of NTC thermistors with high stability, high accuracy and a long service life, such as There is a main theory of liquid level measurement for NTC thermistor. The gas and liquid are different media. If we can distinguish these two media, its easy to solve the problem of liquid level measurement when measuring them with NTC thermistors. Its difficult to judge the media according to the mea...(more)
A Peliter controller is an electronic module, which is designed to control and monitor the temperature of thermal electric coolers (TEC). It has many excellent performances, such as high efficiency, high reliability and high stability. The Peltier controller packaged in a six sided metal enclosure (see Figure 1) can block the interferences between the controller and other electronics. Figure 1. The Peltier controller Users can only select the manual soldering method to solder the Peltier control...(more)
The ATFC105D Peltier controller is designed for controlling and monitoring the temperature of TEC/Fan assemblies. As thisPeltier controller has high efficiency, high stability and high reliability, it has become more and more popular among electronic designers. In addition, as shown in Figure 1, the ATFC105DPeltier controller has a compact size and needs no heat sink during operation, so it is very convenient to use, carry and store. Figure 1. The ATFC105D Peltier controller It is very easy for...(more)
The ATFC105D is a Peltier controller with high efficiency (more than 98%), high stability and high reliability. The Peltier controller is designed to driveand monitor thermal electric coolers (TECs) /fan assembles. It provides a high output power for TECs. As the ATFC105DPeltier controller has a compact size (see figure 1) and there is no need of heat sinksduring operation, it is very convenient to use, carry and store. Figure 1. The ATFC105DPeltier Controller The ATFC105DPeltier controller come...(more)
Analog Technologies, Inc. offers a series of NTC thermistors with or without a ring lug, such as ATH10K1R25 and ATH10KL2B , etc. There is a very important factor in NTC thermistors, dissipation factor. We are looking for the relationship of self-thermal and dissipation factor. Its usually in still air to test the dissipation factor of NTC thermistors. Its often in a glass container. When we do the test, the temperature of the inner glass container should be the same as the room temperature while...(more)
