Temperature Sensor PT100 RTD With Stainless Steel Flange
Product Description:
Resistance temperature detectors (RTD) accurately sense temperature with an excellent degree of repeatability and interchangeability of elements. The RTD is composed of certain metallic elements whose change in resistance is a function of temperature. In operation, a small excitation current is passed across the element, and the voltage, which is proportional to resistance, is then measured and converted to units of temperature calibration. The RTD element is manufactured by winding a wire (wire wound elements) or plating a film (thin film elements) on a ceramic or glass core and sealing the element within a ceramic or glass capsule.
Since most RTDs have a low initial resistance, often 100 ohms, and have a small change in resistance per unit of temperature range, the resistance of the lead wire is often compensated for with a three or four wire bridge configuration built into the measuring devices. By selecting the proper elements and protective sheathing, RTDs can operate in a temperature range of (-200 to 650) °C [-328 to 1202] °F.

Features:
1. Thermal sensor with good shock-proof performance
2. No compensational wire, spare cost
3. High measuring accuracy
4. High mechanical strength, good pressure-resistant performance
5. Imported film resistor with stable & reliable performance
Working principle:
Compensation of the thermocouple wires electrode by the two different conductor material
composition. As measuring end and participate in the end there is temperature difference, can
produce thermoelectric power, the instrument will show thermoelectric potential corresponding
temperature value.
Application:
It is usually connected with display meter, recording meter and computer, etc. to directly measure temperature of liquid, vapor, gas and solid surface ranging from -200 to 500 during various production process.
