What are the accuracy requirements of the instrument of the purchase temperature controller
With the rapid development of society, there are more and more temperature Tamper-proof Thermostat controllers. Many industry departments want to choose some good temperature controllers. Now let’s introduce related matters to select the temperature controller.
To select the temperature controller, you need to consider the range of its measurement. Same as we usually use other instruments, we also need to determine its measurement scale before using temperature controller, otherwise it will simply damage the temperature controller. Just as the measurement component is the same as the temperature controller, the use of the sensor must also know the temperature and humidity scale applicable to the sensor used, so that the relevant knowledge of the temperature controller can be understood, and the temperature controller can be very easy to protect. Otherwise, if the same thing is measured, and the measuring scale beyond the temperature controller, it will simply damage the temperature controller, and will make the measurement results greatly errors. Today, the temperature controller, such as the climate and the scientific research department, usually do not need too high requests for temperature controller and humidity detection and control, that is, do not require full wet range-0 to 100%of RH to measure measurement of 100%. Essence
Then, consider the measurement accuracy of the temperature controller. It is important to choose the measurement accuracy of the temperature controller. The measurement accuracy of the temperature controller is the most important effective indicator of this sensor. As long as a percentage point of the measurement accuracy of the sensor is improved, it seems like a step of the temperature controller, and it can even be said to be a grade. Different working units require different measurement accuracy of the temperature controller, and each measurement of the same thing for each measurement, and the measurement accuracy requested is also different. Therefore, in order to better use the temperature controller or save the money of the purchaser, you must choose the measurement accuracy of the temperature controller you needed. To make different temperature controllers with different measurement accuracy, the cost difference is very large. Of course, the bumps of the capital decide the price of the price. Therefore, the demand purchase temperature controller must steadily select the measurement accuracy of the temperature controller, find the right one, and do not blindly seek high -precision temperature controller in society. This is very simple to make itself suffer, and it will be measured together to bring unnecessary trouble.
Next, we must consider drift and warm drift in the actual application temperature controller. When we use the temperature controller, because of some dust, oil, and some harmful gases, after using it for a period of time, the electronic temperature controller will appear aging Essence Therefore, the general production plant will carefully indicate the effective time of the use of a calibration. It is about one to two years. After expiration, it is necessary to get the calibration.
Of course, when choosing a temperature controller, in addition to the above points, you also need to pay attention. It is best not to choose the temperature controller in an environment with some acidic, alkaline or an organic solvent. In addition, in order to accurately measure the humidity of the space, do not place the temperature controller in a place with the air near the wall and the air. If you want to measure the temperature and humidity of a relatively large space, it is best to use a few temperature controllers to measure together, which can improve the quality of the measured data.
Therefore, whether you choose to buy the temperature controller or the use of the temperature controller, you need to understand the above matters. This can save a lot of unnecessary trouble and improve everyone’s work efficiency.
