Temperature Sensor Rtd Pt100

The difference between pt100 and pt1000 sensors.

Temperature sensor rtd pt100. Shop rtds at automation direct. Rtd or resistance temperature detectors is a temperature sensor that contain a resistor that changes resistance value as its temperature changes. Via transition leads the joints to the extension cable are. Among platinum rtd sensors pt100 and pt1000 are the most common.

Traditionally the detector is built into a protecton tube closed at the sensor ending. A pt100 probe is an assembly composed of an rtd element a sheath a lead wire and a termination or connection the pt100 is a temperature sensor that contain a resistor that changes resistance value as its temperature changes. This blog post discusses many useful and practical things to know about the pt100 sensors. 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.

Pt100 sensors have a nominal resistance of 100ω at ice point 0 c. This document is a part of how to guide for most common measurements centralized resource portal. What is a pt100 probe. The relative change in resistance temperature coefficient.

The rtd pt100 and pt1000 are available in a similar range of tolerances and both can have similar temperature coefficients depending on the purity of the platinum used in the sensor. Rtd overview a platinum resistance temperature detector rtd is a device with a typical resistance of 100 ω at 0 c. Pt100 rtd sensors content general about pt100 rtd with cable process sensors hygienic surface air temperaure iec 60751 temperature ranges general about pt100 rtd pt100 probes mainly are designed in two ways. Resistance temperature relationship of metals.

Pt100 probes may be terminated in a connection head quick disconnect terminal block or extension wire. The pt100 temperature sensors are very common sensors in the process industry. Pt100 temperature sensor pinout click the image to enlarge it pin configuration. Pt1000 sensors nominal resistance at 0 c is 1 000ω.

There s information on rtd and prt sensors different pt100 mechanical structures temperature resistance relationship temperature coefficients accuracy classes and on many more. When comparing the pt100 vs pt1000 in terms of resistance keep in mind that resistance value readings for the pt1000 will be higher by a factor of ten than. There are many types of pt100 sensors the one we use here is a two wire one. Its resistance varies with temperature and it can typically measure temperatures up to 850 c.

The pt100 sensor is just like a variable resistor whose resistance varies with respect to the environment temperature. Common rtd sensing elements constructed of platinum copper or nickel have a repeatable resistance versus temperature relationship r vs t and operating temperature range the r vs t relationship is defined as the amount of resistance change of the sensor per degree of temperature change.
