German imports PT1000 platinum thermal resistance factory asking price

The installation of the temperature of the temperature sensor using the

today and share is temperature temperature sensor installation, hope to help you!

error of thermal resistance at high temperature, such as protecting tube with a layer of ash, dust attached to the above, the thermal resistance increase, hinder the heat conduction, when the temperature is lower than the true value of measured temperature value. Therefore, we should maintain the cleanness of thermocouple protection tube outside, to reduce the error.

specialized production provides temperature temperature sensor, if you want to know more products information you can call the company telephone consultation! Serve you wholeheartedly! ！ ！

the characteristics of the temperature sensor temperature

the temperature is very common in industrial production, an important thermal parameters. Many production processes on the process requirements of temperature monitor and control; Some devices will its running state is normal on the temperature had obvious reflection, according to the temperature and its change can understand mechanical and electrical equipment running condition and fault.

the temperature is hot or cold degree of a physical quantity measurement object. Temperature cannot be directly measured, and by means of some physical properties of an object ( Such as heat bilges cold shrink, thermoelectric effect, etc. ) To indirectly measure.

temperature classification and working principle of the temperature sensor is introduced

temperature probe or probe, known as the temperature, relative to other temperature sensor, the scope of its application more widely, so it has a large market share in the market.

temperature temperature sensor is can feel temperature is converted into usable output signal of the temperature sensor. Temperature temperature sensor is the core part of the temperature measuring instrument, wide variety. Temperature temperature sensor for temperature measurement is accurate, is widely used in agriculture, industry, workshop, warehouse, etc.

the category of the temperature sensor and the temperature?

temperature sensor material and electronic component features divided into two categories, thermal resistance and thermocouple.

（ 1) Thermocouple

mV output, can be transformed into 4 ~ 20 ma output. S, B, E, K, R, J, T seven standardization thermocouple type thermocouple for China unified design.

（ 2) Thermal resistance

output resistance value, commonly used Pt10, Pt100, Pt1000, Cu50 and Cu100.

0 ℃ resistance to 10 Ω Pt10 said.

how to select the correct of the thermistor temperature sensor for temperature

bom cost thermistor itself the price is not expensive. Because they are discrete, so can through the use of additional circuit to change the voltage drop. For example, if you are using a nonlinear NTC thermistor, and hope for a linear voltage drop in on the device, can choose to add additional resistor to help implement this feature. However, another can reduce the total cost of the BOM and solution alternative is to use linear thermistor itself to provide the required pressure drop. The good news is that with the help of our new linear thermistor series, engineers can simplify the design, reduce the system cost and the printed circuit board ( PCB） At least a 33% reduction in the layout of the size.
