Model No.: WZP-230 Assembly thermal resistance pt100
Resistance Temperature Detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes. They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability.
The RTD is one of the most accurate temperature sensors. Not only does it provide good accuracy, it also provides excellent stability and repeatability. RTDs are relatively immune to electrical noise and therefore well suited for temperature measurement in industrial environments, especially around motors, generators and other high voltage equipment.
Applications of RTD's include:
L Air conditioning and refrigeration servicing
2 Food Processing
3 Stoves and grills
4 Textile production
5 Plastics processing
6 Petrochemical processing
7 Micro electronics
8 Air, gas and liquid temperature measurement
9 Exhaust gas temperature measurement
RTDs vs. Thermocouples
The two most common ways of measuring industrial temperatures are with resistance temperature detectors (RTDs) and thermocouples. Choice between them is usually determined by four factors.
Temperature: If process temperatures are between 200 to 500 ° C (328.0 to 932 ° F), an industrial RTD is the preferred option. Thermocouples have a range of 180 to 2, 320 ° C (292.0 to 4, 210 ° F), so for temperatures above 500 ° C (932 ° F) they are the only contact temperature measurement device.
Response time: If the process requires a very fast response to temperature changes— Fractions of a second as opposed to seconds (e. G. 2.5 to 10 s)— Then a thermocouple is the best choice. Time response is measured by immersing the sensor in water moving at 1 m/s (3 ft/s) with a 63.2% step change.
Size: A standard RTD sheath is 3.175 to 6.35 mm (0.1250 to 0.250 in) in diameter; Sheath diameters for thermocouples can be less than 1.6 mm (0.063 in).
Accuracy and stability requirements: If a tolerance of 2 ° C is acceptable and the highest level of repeatability is not required, a thermocouple will serve. RTDs are capable of higher accuracy and can maintain stability for many years, while thermocouples can drift within the first few hours of use.
