Human survival and social activities are closely related to temperature control. With the realization of modernization, It is difficult to find a field that has nothing to do with the temperature. Due to different application areas, Technical requirements for temperature-controlled switches are also different. From the manufacturing point of view, The same is the temperature control switch, material, structure, process different. Its performance and technical indicators will be very different, So the price is also very different. For the user, Select the temperature control switch, First of all, need to find out what kind of temperature control switch; Their financial resources to buy what grade allows the temperature control switch, Will not blindly act. We from the user's contacts, Think there are several issues worth noting.

1. Select the measurement temperature range, Select the temperature control switch first to determine the measurement range. In today's information age, Temperature control switch technology and computer technology, automatic control technology closely. The purpose of measurement is to control, The measuring range and the control range are collectively called the temperaturecontrol range. Of course, do not need to engage in monitoring and control system for the application, Directly select the general-purpose KSD301 temperature control on it. The user needs to be made to the temperature control switch factory measuring range, The factory will give priority to ensure that users within the scope of the stability of the same temperature control switch, Reasonable cost performance, The two sides complement each other in terms of is a thing.

2, select the temperature control switch measurement accuracy, Measurement accuracy is the most important indicator of temperature control switch. Each increase - percent. On the temperature control switch is the last step, Or even on a grade. Because to achieve different accuracy, Its manufacturing cost is very different, The price is also very different. For example, an ordinary low-cost temperature control switch only a few cents, The high-precision temperature control switch will need a few dollars, A difference of nearly 10 times. TheTo the user must be tailored, Should not blindly pursue "high, refined, sharp. "Manufacturers are often segmented given the temperature control switch accuracy. Such as medium and low accuracy (10%, 5%, 3%), While high accuracy (1%, 2%). Such as at different temperatures using temperature control switch. The indication also takes into account the effect of temperature drift.
in most cases, If there is no precise means of temperature control, Or the measured space is unsealed, ± 5% accuracy is sufficient. For the requirements of precise control of constant temperature local space, Or need to keep track of the temperature changes of the occasion, And then use more than ± 3% accuracy of the temperature control switch. Corresponding to the temperature sensor. The temperature accuracy must meet ± 3 ℃ above, at least ± 2 ℃. While the accuracy of more than ± 2% of the requirements I am afraid even the standard temperature sensor calibration sensor is also difficult to achieve, Moreover, the temperature control switch itself. National Standard Material Research Center of temperature control switch article that:"Relative temperature control switch, Even at 20-25 & lt; 0 & gt; To achieve 2% accuracy is still very difficult.
3, the temperature control switch input and output voltage selection:Some brands of temperature control switch to support multi-voltage input, First of all, to ensure that the input voltage and allow the input voltage to ensure consistency. There is no excessive demand for AC, Mainly with DC power supply, Must pay attention to positive and negative wiring, Can not be reversed, Otherwise it will burn out the temperature control switch. So we recommend the use of AC power supply temperature control switch. Another point is to put forward, Is that some of the temperature control switch does not support the DC on-off, Or can be broken off the DC voltage is small, This time in the purchase of temperature control switch keep up with business consulting clear, So as to avoid unnecessary trouble.
