The
Importance of Temperature Sensor for Industrial Production
With the
continuous improvement of the industrial production efficiency, the expansion
of the automation level and the scope, the demand for the temperature sensor is
also higher and higher, and the following aspects are summarized:
Extended
temperature measurement range: at present, the commonly used temperature
measurement range is-200C-3000 ℃. With the development of industry, the measurement requirements of
ultra-high temperature and ultra-low temperature are becoming more and more
urgent, such as thousands of degrees of high temperature often need to be
measured in cosmic rocket technology.
The
measurement accuracy is improved. With the development of the electronic
technology, the accuracy of the signal processing instrument is greatly
improved, in particular the use of the microcomputer makes the processing
precision of the signal more improved.
Expand
the temperature measurement object: with the improvement of industry and
people's daily life requirements, it has now developed from point measurement
to line and surface measurement. All kinds of temperature measuring instruments
are needed in environmental protection and household appliances.
A new
product is developed to meet the special needs: in the temperature measurement,
in addition to further expanding and perfecting the tube cable thermocouple,
the thermal resistor, and the transistor temperature measuring element, the
rapid and high-sensitivity common thermocouple, and according to the
environment of the tested object, a number of special requirements are set
forth. Such as anti-sulfur, explosion-proof, wear-resistant thermocouples,
continuous temperature measurement of molten steel, flame temperature
measurement, and the like.
The
digital thermometer not only has the characteristics of direct reading, no
error, high resolution and small measurement error, but also brings great
convenience to the intellectualization of the temperature instrument
Verification
automation: because the temperature calibration device will directly affect the
quality of the temperature instrument, it is worth making great efforts to
study in this area. A thermocouple calibration device controlled by
microcomputer has been developed in China.
