About the temperature of the temperature sensor selection problem

temperature temperature sensor selection is mainly based on the measurement range. When the measuring range is expected within the total range, can choose platinum resistance temperature sensor. Narrower range usually require basic resistance temperature sensor must have a fairly high, in order to get enough resistance change. Thermistor provided enough resistance change makes these sensitive element is very suitable for narrow measuring range. If the measuring range is quite large, thermocouple more applicable. Will also include freezing in this range, because of the thermocouple indexing table is based on temperature. Known within the scope of linear temperature sensor also can be used as a selection of the temperature sensor of strings attached.

response time is usually expressed in time constant, it is to choose another fundamental basis temperature sensor. When you want to monitor temperature storage tank, the time constant is not so important. However, when in use process must measure the temperature in the tube, vibration time constant becomes decision factor to choose temperature sensor. Bead type thermistor and armoured outcrop type thermocouple time constant is fairly small, and immersion probe, especially the thermocouple with protective casing, time constant is larger.

the dynamic temperature measurement is more complex, it is only through repeated tests, as far as possible close to simulate the temperature sensor used in the condition of frequent, to achieve reasonable approximate temperature sensor dynamic performance.

temperature sensor or temperature measuring

the multimeter resistance RX20K measurement can be. Average temperature sensor is a 5 k, 10 k, 15 k, the temperature sensor has a resistance value is, if and marked on the actual is the huge difference between resistance drift. Or your hand holding the head of the temperature sensor, and then measure the resistance if there is any change, if resistance has been still means that it is bad!

air conditioning temperature when the temperature sensor performance is good or bad, the air conditioning that decide frequency should be set in the state of forced cooling, the frequency conversion air conditioning should be set in the test run state. If the air conditioner can operate, and the working current basic normal, can generally be considered bad temperature temperature sensors. Air conditioning temperature temperature sensor resistance becomes big or compressor temperature temperature sensor resistance small, will cause the inverter output frequency is low, influence the refrigeration effect

temperature thermal resistance temperature sensor structure

today and share is temperature thermal resistance temperature sensor structure, hope to help you!

end face temperature thermal resistance temperature sensor end face temperature of thermal resistance heat temperature sensor resistance wire winding by special processing, close to the face in the thermometer, it is compared with general axial temperature thermal resistance temperature sensor, can more accurately and quickly to reflect the actual temperature of end face, is suitable for measuring temperature bearing and other parts of the face.

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.
