When we are testing the relevant data of the thermistor, we basically use a multimeter to detect it. Generally, it is basically divided into the following
Steps: The first step is to perform indoor room temperature testing. At this time, the indoor temperature is required to be close to 25 degrees Celsius. Then we don't need
To use the test leads for testing, you need to replace the test leads with alligator clips, and use our alligator clips to clamp the ends of the PTC thermistor.
Measure the actual resistance of the thermistor, and compare it with our nominal resistance, if the actual measured resistance is with us
If the nominal resistance difference is based on the upper and lower 2 ohms, it means that the thermistor is normal. On the contrary, if the actual measured resistance is
If our nominal resistance is very different, this means that our thermistor is damaged or poor performance, then its
The thermistor can no longer be used.
The second one is that we warm up to test. If we say that the data we tested at normal temperature is normal, we still don’t put it on the thermistor.
In the heart, we can carry out the second heating test. We need to put a heat source such as a soldering iron on the side of the thermistor to be tested.
Heating, when heating to a certain level, we need to observe the value of the multimeter. Under normal circumstances, the value of our multimeter will
As the temperature changes, slowly, when the value of the multimeter rises to a certain value, it will stabilize.
The thermistor is normal. On the contrary, if there is no change in the resistance, this time, our thermistor is completely broken.
, can no longer continue to use, must be replaced with new ones. Http://
1. Product introduction
Coal-based Column Desulfurization Column Activated Carbon used high quality anthracite as raw material. Adding a certain proportion of adhesive, auxiliary catalyst, by selection, proportioning, grinding, molding, drying, carbonization, activation and deep processing made.
2. Application
This product is mainly used in all kinds of gas, such as water gas, semi water gas, coke oven gas, natural gas, carbon dioxide gas, city gas, synthetic ammonia process gas, and exhaust gas in sulfur dioxide chemical raw materials and other containing mercury. It also used for adsorption of flue gas of power plant equipment, including the removal of sulfur dioxide and saltpeter, which replace the lime desulfurization process before. It also applies to other gas that contains mercury cannot get rid of the low concentration, which is equal to or below the national emission standard.
3.Transportation and Packing
Woven bag, lined with plastic film bags, each 25kg can also be packaged according to customer demand. The product should be placed in a cool and dry place during storage; When transportation, it prevents to mixed with hard materials, to prevent carbon particles broken that affecting the quality of packaging, to prevent breakage. To avoid leakage or mixed with debris; to avoid water, oil and fire.
