SUS304 Movable Thread RTD Temperature Sensor Stable Performance

Assembly RTD Various Styles Support Customization Stable Performance

The assembled thermistor measures the temperature by using the characteristic that the resistance of the material changes with the change of temperature. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the medium where the temperature sensing element is located.

1. Assembled thermistor

The assembled thermal resistance for industrial use is mainly composed of temperature sensing element, temperature sensing probe, transition protection and signal cable, and is equipped with various installation and fixing devices.

1) Temperature sensing element: imported thin film platinum resistance PT100 temperature sensing element.

2) Protection tube: according to the type of assembled thermal resistance, the measured medium condition and the measured temperature, the protection tube made of different materials is selected. The protection tube of thermal resistance is generally made of carbon steel, various brands of stainless steel, alloy steel and other materials.

3) Installation and fixing device: the assembled thermal resistance installation and fixing device is used for installation and fixing by users. It is divided into various forms, such as no fixing device, fixed thread, movable flange and fixed flange.

3. Product application

As a temperature measurement sensor, the assembled thermal resistance is usually used together with temperature transmitter, regulator and display instrument to form a process control system, which is used to directly measure or control the temperature of liquid, steam, gas medium and solid surface in various production processes.

PT100 Sensor Technical information:

As for the thermocouple, we split the word: Pt and 100. Pt is the chemical symbol for Platinum, 100 is the resistance in Ohm of the Pt100 at 0 °C. The resistance changes (fearly linear) with temperature are: 0.385 Ohm/°C for European and 0.392 Ohm/°C for American elements. So, by measuring the resistance we can calculate the temperature. Never use a European Pt100 with an American instrument unless you know that it is set for the right conversion factor (usually called 'alpha'). In english a Pt100 is also called a RTD element, meaning Resistance Temperature Detector.

An RTD or Pt100 sensor is connected with two, three or four wires to the measuring device. we learned that we are in fact measuring resistance to determine the temperature. Now when measuring the resistance of the sensing element, we also measure the resistance of the leads and cables used. This gives an error! To compensate for this, the three wire type (bridge) is used, giving enough accuracy in most industrial applications. Even better accuracy is possible with a four wire Pt100 (laboratory applications). Our Pt100 panel mounted indicators have an offset compensation when using two wire sensors.

If you want high accuracy, for example better then 0.5°C between 0 and 100°C, go for the Pt100.
