The causes of errors temperature temperature sensor

at higher or lower temperature measured medium temperature sensor output does not change, this kind of situation is mostly temperature problem of temperature sensor seal, may be due to temperature, temperature sensor is not sealed or accidentally when welding will be a small hole, welding temperature sensor that generally need to replace the temperature sensor shell to solve it. The output signal is not stable, the cause of the reason is that temperature source ability, temperature source skill is an unstable temperature, if the meter is not stable, that is the reason why the anti-interference ability of the instrument is not strong. Temperature sensor output error is big, because this kind of circumstance is more, may be to choose the temperature of the temperature sensor resistance wire wrong lead to range error, there are also can not to be temperature sensor calibration.

what are the main application field, temperature temperature sensor range?

temperature temperature sensor in the market now using range is very wide, is mainly used in some computer measurement and control system is more, so everyone can see it in use process has the characteristics of the professional manufacturers, production, processing and the quality of the instrument is very good, and on the testing data is also very accurate, also from this point can be judged from the realm of product specific use.

used in the petrochemical industry is more

petrochemical industry are need to use the temperature sensor temperature, because it is in use process need to effectively control the temperature of the site, once the temperature is not reasonable, or abnormal situation, need to be timely and effective solution. Recommended when using can also take a look at the overall measurement way, of course also with other instruments are needed to use, can play a better role.

field temperature control in the field of food industry

food industry was also need to use this product, because it is at the scene of the production need to control temperature, if not timely and effective control, may also bring a lot of influence, we suggest that we should be detailed understanding of the use place, food industry and building materials industry, should be reasonably choose to use the product.

the above content can also be found, as a common kind of temperature measurement and control products, involved in the process of using temperature temperature sensor has a very wide range of industries, the demand of petroleum and chemical industry is very much, and in the power industry are also widely used in building materials industry. Use effect is very good in computer measurement and control system, with the instrument used to detect data is very accurate, very convenient also.

choose the basic principle of temperature sensor temperature

survey scope, the output signal is with the user of temperature measuring temperature range corresponding to the selected survey scope should be larger than the actual application scope, a certain amount of leeway, normal temperature range of practical application accounts for only about 70% of the survey scope;

conditions of use, using background temperature requirements shall be depending on the specific location, wide temperature range of outdoor must choose to use in the north; And in the south of the Yangtze river region or indoor requirements can be lower. Survey should be paid attention to in high temperature, temperature of temperature sensor plate temperature can not exceed the prescribed scope, or should choose wall temperature sensor, or repay the wires away a bit; Power supply voltage fluctuation, the influence of load resistance change on surveying precision and the background of temperature error is smaller.
