Medical surge in demand for infrared sensor, temperature sensor for market burst?

According to Global Market Insights, recently, according to the 2019 Global temperature sensor Market size of more than $7 billion, estimates from 2020 to 2026, with compound annual growth rate of 4% growth. Market growth from the automotive, health care and manufacturing and so on, the measuring accuracy and measuring range has a very high requirements.

Conceptually, the temperature sensor is to point to can feel temperature translates into usable output signal of the sensor.

According to measuring methods can be divided into two types: contact and non-contact.

1, contact

Contact temperature sensor detection part of the measured object and has a good contact, also called a thermometer.

Thermometer reach thermal equilibrium by conduction and convection, which makes the value of the thermometer can directly said the temperature of the object to be tested.

General measure precision is higher. At a certain temperature range, the thermometer can measure the temperature distribution within the object. But for the movement of body or heat capacity is very small, small target object will produce larger error of measurement, the commonly used liquid thermometer with double metal thermometer, glass thermometer, pressure type thermometer, resistance thermometer, thermistor, thermocouple, etc. They are widely used in industry, agriculture, business, etc. People often use the thermometer in our daily life.

2, non-contact

The measured object, sensitive element and contact each other, also known as non-contact thermometer table. This instrument can be used to measure the moving objects, small target has a smaller thermal capacity and temperature changes or (transient) of the object surface temperature quickly, can also be used to measure the temperature of the temperature field distribution.

The most commonly used non-contact thermometer table based on the fundamental laws of blackbody radiation, known as radiation thermometer table. All kinds of radiation temperature measurement method can only detect the corresponding luminosity temperature, radiation temperature or colorimetric temperature. Only the blackbody (all absorbed radiation is not reflected light objects) is the true temperature measurement temperature. If you would like to determine the true temperature of the object, the material surface emissivity correction must be conducted. And emission rate depends not only on material surface temperature and wavelength, but also with the surface state, coating, and microstructure and so on, so it is difficult to measure accurately.

Non-contact temperature sensor has the advantage of measurement limit is not restricted by thermal components heat resistance level, and therefore there is no limit of maximum temperature measurement in principle.

According to the temperature sensor output signal model, can be roughly divided into three broad categories: digital temperature sensor, temperature sensor, analog temperature sensor logic output.

1, digital temperature sensor

It USES the production of silicon digital temperature sensor, the structure of PTAT, the semiconductor structure is precise, good output characteristics related to temperature.

2, logic output temperature sensor

In many applications, we don't need strict measuring temperature, only care about whether the temperature is beyond the scope of a set, once the temperature is beyond the scope of, emit alarm signals, on or off the fan, air conditioner, heater, or other control device, logic output type temperature sensor is optional at this time.

3, analog temperature sensor

Analog temperature sensor, such as thermocouple, thermal resistance and RTDS for temperature monitoring, in some linear temperature range is bad, need to undertake the cold end compensation or lead compensation; Thermal inertia is big, slow response time. Integration compared with analog temperature sensor with high sensitivity, good linearity, fast response speed, and it will also drive circuit, signal processing circuit and the necessary logic control circuit integration in monolithic IC, has practical advantages of small size, easy to use. Common analog temperature sensor are LM3911, LM335, LM45, AD22103 voltage output type, AD590 current output type.
