The principle of platinum resistance temperature measurement is the principle that the resistance value of the platinum resistance increases as the temperature increases.
Thermal resistance (PT100) is designed and manufactured using the basic principle that the resistance value of platinum wire changes with temperature. According to the resistance value R (℃) at 0℃, it is divided into 10 ohms (graduation number Pt10) et 100 ohms (graduation number Pt100), etc.. The temperature measurement range is large, suitable for -200~850℃. The temperature sensing element of the 10 ohm platinum thermal resistance is made of thicker platinum wire, and its temperature resistance is obviously better than that of the 100 ohm platinum thermal resistance. Mainly used in the temperature zone above 650℃: 100 ohm platinum thermal resistance (PT100) is mainly used in the temperature zone below 650℃. Although it can also be used in the temperature zone above 650℃, the A-level error is not allowed in the temperature zone above 650℃.
What is a platinum thermal resistance?
The resolution of a 100 ohm platinum thermal resistance is 10 times greater than that of a 10 ohm platinum thermal resistance. The requirements for the secondary instrument are correspondingly more than an order of magnitude, so 100 ohm platinum thermal resistance (PT100) should be used as much as possible to measure the temperature in the temperature zone below 650 ℃.
The material of the frame of the temperature sensing element (PT100) is also the main factor that determines the temperature zone of the platinum thermal resistance. Common temperature sensing components include ceramic components, glass components, and mica components. They are made of platinum wire wound on the ceramic framework, glass framework and mica framework respectively, and then processed by complicated processes. Due to the different properties of the framework material itself, ceramic components are suitable for temperature zones below 850°C, and glass components are suitable for temperature zones below 550°C. There are a large number of thick film and thin film platinum thermal resistance temperature sensing elements on the market. The thick film platinum thermal resistance element is printed with platinum paste on the glass or ceramic base plate, and the thin film platinum thermal resistance element is sputtered with platinum paste on the glass or ceramic base plate, and then processed by photolithography. This kind of temperature sensing element is only suitable for the temperature range of -70~500℃, but this kind of temperature sensing element uses less materials, can be mechanized and mass-produced, has high efficiency and low price.
In terms of structure, platinum thermal resistance can also be divided into industrial platinum thermal resistance and armored platinum thermal resistance. Industrial platinum thermal resistance is also called assembling platinum thermal resistance, c'est, the platinum thermal resistance temperature sensing element is welded on the lead wire and assembled in a metal tube or ceramic tube with one end closed, and then a junction box is installed; The armored platinum thermal resistance is a whole assembled by the platinum thermal resistance element, the transition lead, and the insulating powder in the stainless steel tube and then the die is pulled. It has the advantages of being solid, anti-vibration, winding, small wire diameter, easy to use and install, etc..

NTC Temperature Sensor
What Is The NTC Temperature Sensor? NTC temperature sensor is an thermistor after the wire welding, encapsulate into a different probe and then use an epoxy seal. The temperature sensor retains all the features of the thermistor. After the optimization of the injection and cooling stages, will be made into a complete product, mass production is a continuous cycle of this processing step produced.
Production of platinum temperature sensor
STT-M series temperature sensors Probe are packaged with magnetic bodies. For paramagnetic metal surfaces, it can be easily sucked to the surface for temperature measurement and can be easily installed and removed. It is suitable for the detection of the key point temperature of large equipment before leaving the factory, and other occasions where the temperature detection point needs to be replaced frequently, so as to improve the efficiency of temperature detection
PT100 RTD sensor Probe & Câbles
PT100 thermal resistance acquisition modules can be connected to the RS-485 local control network through the isolated 485 communication interface. RS-485 allows up to 32 PT100 thermal resistance acquisition modules to be hung on the same bus. Cependant, if Link-Max's RS-485 repeater is used, up to 256 PT100 thermal resistance acquisition modules can be connected to the same network, and the maximum communication distance is 1200m.
RTD PT100 Temperature Sensor Probe with Cable
What is a Platinum thermal resistance sensor?
An RTD (Resistance Temperature Detector) is a Platinum thermal resistance whose resistance changes with changes in temperature. Its resistance increases as the sensor temperature increases. The relationship between resistance and temperature is well known and repeatable over time. RTD is a passive device. It does not produce output by itself. External electronics can be used to measure the sensor resistance by passing a small current through the sensor to produce a voltage. Typically 1 mA or less measurement current, maximum 5 mA, without risk of self-heating.
What is thermocouple sensor?
The appearance of various thermocouple sensor probes is often very different due to needs. Cependant, their basic structures are roughly the same, usually composed of main parts such as a thermode, an insulating sleeve protection tube, and a junction box, and are usually used in conjunction with display instruments, recording instruments and electronic regulators.
