What is a Pt100 probe?
If you have been wondering what a Pt100 probe is, then you are not alone. The Pt100 probe is basically the assembly that consists of the RTD’s element, one sheath, one lead wire & also one terminal or one connection. The Pt100 happens to be a temperature sensor, which contains one resistor, which tends to change the resistance value when there are changes in the temperature. Such a type of probe is commonly used in temperature measurement and control, and it is important to understand how it works in order to get accurate readings. The Pt100 probe is used in a variety of applications including temperature measurement, process control, and thermal management. The Pt100 probe has a wide range of temperature ratings and can be used in both Cryogenic and High Temperature applications. The Pt100 probe can be terminated with a variety of lead wires and sheaths.
A Pt100 probe could be terminated inside a connection head, in the fast disconnect, in the terminal-block or also in the extension wire. The standard terminations are described on the product-related pages. Other styles of termination are available by special order.
Pt100 probes also have lead wires, which are used to connect the probe to a measuring device. The lead wires are usually made of copper or another conductive material. Lead styles & RTD cables of extension tend to be provided in 1 of the 4 configurations. Style two is the standard. Ensure selecting a configuration, which matches the instrumentation. Some probes are also available with different types of lead wires, depending on the application.
A Pt100 probe consists of a Pt100 element, which is a resistive material that changes resistance with temperature.
The standard RTD probe has been built from a 100 ohm European platinum curved element (á = 0.00385).
The element is encased in a sheath, which is typically made of stainless steel. The sheath protects the element from damage and also helps to ensure accurate readings. The sheath, the tube with a closed end, secures the element and also protects it against any moisture content & other environment for measurement. The sheath too gives protection as well as stability for the lead wires of transition of the sensitive element wires. The standard sheaths are 3 mm (1/8″) & 6 mm (1/4″) O.D. 304 tubes made of stainless steel material.
Pt100 probes are available in a variety of temperature ratings, which determine the range of temperatures that the probe can accurately measure. “PR” Style of the RTD’s probe assemblies have been rated to be used in temperatures largely up to even 600 degree Celsius (1110 degree Fahrenheit). The style sensor of “PRTF” has been rated up to the range of 260 degree Celsius or 500 degree Celsius as per the design. The limitations for the temperatures might be placed upon the styles of termination because of the insulation used in the wire. The rating of maximum temperature has been made available by special order, and it can be 750 degree Celsius (1380 degree Fahrenheit).
If you have been looking for accurate temperature readings, a Pt100 probe is a great option. This type of probe consists of a thin wire that is wrapped around a metal rod. The wire is then connected to a monitoring device. Pt100 probes are often used in industrial settings, as they are able to withstand high temperatures. They are also available in different sizes and with different lead wire and sheath options, so you can choose the best option for your needs. Keep in mind that the element and temperature rating of the Pt100 probe will affect its accuracy. When using a Pt100 probe, it is important to choose the right termination for the lead wires. This will ensure that the readings are accurate and that the probe is properly connected to the measuring device. For procuring the right type of products, you can come to Heatcon!
