NTC Thermistor- Wind Velocity Measurement

NTC thermistors are sensitive to air flow when they are in self-thermal status, so NTC thermistors has potential to measure wind velocity. Under the same temperature and electric condition, such as stable room temperature, provide a constant current to NTC thermistors for self-thermal. Put NTC thermistors in still air, at this time, the terminal voltage is the lowest. Then increase the wind velocity generally, and the terminal voltage increases accordingly. That’s because the flow air decreases the self-thermal temperature of NTC thermistors, and the resistance increases. More fast is the flow air, more obviously the temperature falls. Vice versa, when we know how much the self-thermal temperature falls by detecting the terminal voltages, we can know the wind velocity. This is the principle of wind velocity measurement.

NTC Thermistor-Liquid Level Measurement (III)

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 can’t 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 need to be measured at the same time, but generally, it’s hard to measure temperature when NTC thermistors are self-thermal. Therefore, another NTC thermistor is needed. By using two NTC thermistor, one in self-thermal, and the other not. Then we can measure the liquid level after processing in electronic circuit. Likely, the liquid level measurement in other gas or liquid media can be solved.

NTC Thermistor-Liquid Level Measurement (II)

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. That’s because when NTC thermistor enters into the water, the temperature falls, resulting in a resistance increase and the terminal voltage increase. The heat capacity of water is 2.5 times higher than the air, so the self-heat temperature in the water needs 2.5 times power than that in the air.

NTC Thermistor-Liquid Level Measurement (I)

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, it’s easy to solve the problem of liquid level measurement when measuring them with NTC thermistors. It’s difficult to judge the media according to the measurement result when NTC thermistors measure temperature at zero power, i.e. non-natural state. When NTC thermistors are in self-thermal state and the temperatures of the media keeps the same, the dissipation factors of NTC thermistors are different. When NTC thermistors are in different media under the same electrical conditions, they will show different electrical performances. This is the basis of liquid level measurement.

NTC Thermistor-Dissipation Factor

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.

It’s usually in still air to test the dissipation factor of NTC thermistors. It’s 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 the air in the room is relatively stable. Firstly, measure the zero power resistance. After removing the glass container, the resistance keeps the same; then measure the dissipation factor. When the self thermal reaches a thermal balance, i.e. the current and terminal voltage of the NTC thermistors keep stable. When removing the glass container, the current or the terminal voltage fluctuate, thus losing the stability. This denotes that the weak same temperature air influences the dissipation factor, but not the zero power resistance. Obviously, self-thermal NTC thermistors are sensitive to the flow air, which is a useful characteristic.

In addition, there is a compensation network, which is used to match the thermal load characteristics and can help to obtain high temperature stability and high response speed. 

Besides ATEC24V10A1Peltier controller, there are many other Peltier controllers in stock, such as ATFC105D, TECA1-XV-XV-D and so on. You can choose what you want, and we can also customize a Pletier controller based on your demands.

The Characteristics of Peltier Controller ATW3A314

ATW3A314 is the part number of an ATIPeltier controller, which is designed for monitoring and controlling the actual objet temperature. ATW3A314Peltier controller has high efficiency, compact size and high stability. Besides monitoring and controlling the temperature, this Peltier controller can also be used to switch frequency synchronizedto an external signal. The photo followed is the physical photo of an actual ATW3A314Peltier controller.

ATW3A314 Peltier controller comes with a programmable set-point temperature window, and users can set the required object temperature. This Peltiercontroller has a standby indication, when the temperature is within the pre-set object temperature, it will go into standby mode automatically. As thisPeltier controller is packaged in a six side metal enclosure, it has the capacity of blocking the interference between the Peltier controller and other electronics. There are two packaging methods available,DIP and SMT packages.

Main Applications of NTC Thermistor (I)

Thermistor is a semiconductor component whose resistance changes significantly with the change of the (sensed) temperature. It’s called NTC thermistor when its resistance decreases when the temperature increases. NTC thermistor is widely used in home appliances. 

There are some main parameters for NTC thermistor:

1. Self-heating: When we measure or use NTC thermistor, there is always a current going through it, and this current heat up the thermistor. When self-heating occurs, the resistance of NTC thermistor drops, which produces some dynamic changes in measurement and other application. Therefore, it is critical to control self-heating. It should avoid self-heating when using NTC thermistor in temperature measurement. It should take advantage of self-heating when it is used in liquid level or wind speed measurement.

There are various types of NTC thermistor in Analog Technologies, Inc., such as ATH100KR8 and ATH10KR8B, etc. Moreover, we also provide NTC thermistor with a ring lug outside its thermistor head, which is used for easy mounting and fixing. More types of NTC thermistors with high stability and accuracy can be found in our website.

Main Applications of NTC Thermistor (II)

Continued from last article… 

2. Zero Power Resistance: Zero power resistance is the most basic parameter of NTC thermistors. The resistance given by the manufacturer belongs to zero power resistance. However, ‘zero power’ confuses some customers since zero power doesn’t exist in physical meanings. Actually, the change of the resistance caused by self-heating can be neglected when comparing with the total measurement error. Generally, the zero power measurement of NTC thermistor is made in thermostatic bath, therefore, there are two main factors which influence the measurement error: one is the current through NTC thermistor, and the other is the accuracy of the thermostatic bath. In general, there are many ways to decrease this current, and when the current is reduced to a certain level, it’s the accuracy of the thermostatic bath that influences the total measurement error.
