5X00063G01  Comparison of traditional and digital temperature sensors

Temperature sensor is the core of temperature measuring instrument, its variety, in a variety of industries are widely used. Today, temperature sensors in the market are generally divided into traditional temperature sensors and digital temperature sensors, so which is better? Here is a brief comparison for learning. From China Sensor Trading Network

5X00063G01 Temperature sensors on the market can be roughly divided into traditional temperature sensors and digital temperature sensors, both of which are widely used. These two sensors have their own characteristics and applications, now can not completely say which is good which is not good, at present can only say that each has its own advantages.

The digital temperature sensor is different from the traditional thermistor, the use of integrated chip, the use of single bus technology, it can effectively reduce the external interference, improve the measurement accuracy, at the same time, it can directly convert the measured temperature into a serial digital signal for microcomputer processing, the interface is simple, so that data transmission and processing simplification. The integration of some functional circuits makes the overall hardware design more concise, can effectively reduce costs, build circuits and welding circuits faster, debugging is more convenient and simple, which shortens the development cycle.

Most of the traditional temperature 5X00063G01 detection with thermistor as a sensor, the use of thermistor, can meet the 40 degrees Celsius to 90 degrees Celsius measurement range, but the thermistor reliability is poor, low temperature measurement accuracy, for 1 degree Celsius signal is not applicable, but also through a special interface circuit converted into digital signals can be processed by the microprocessor.
General principles for sensor selection

5X00063G01 Modern sensors vary greatly in principle and structure, how to select sensors reasonably according to the specific measurement purpose, measurement object and measurement environment is the first problem to be solved in the measurement of a certain quantity. When the sensor is determined, the corresponding measurement method and measurement equipment can be determined. The success or failure of the measurement results depends to a large extent on whether the selection of sensors is reasonable.

1, 5X00063G01  according to the measurement object and the measurement environment to determine the type of sensor

To carry out a specific measurement work, we must first consider what principle of the sensor, which needs to analyze various factors to determine. Because, even if the measurement of the same physical quantity, there are a variety of principles of the sensor is available, which principle of the sensor is more suitable, you need to consider the following specific problems according to the characteristics of the measurement and the use of the sensor conditions: the size of the range; The sensor volume requirements of the measured position; Whether the measurement mode is contact or non-contact; Signal extraction method, wired or non-contact measurement; The source of the sensor, domestic or imported, whether the price can be borne, or self-developed.
