Rtd Pt100 Temperature Sensor

Rtd or resistance temperature detectors is a temperature sensor that contain a resistor that changes resistance value as its temperature changes.

Rtd pt100 temperature sensor.

Pt100 rtd sensors rtd probes rtd transmitters sanitary rtds other industrial temperature sensors at discount prices. 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. Among platinum rtd sensors pt100 and pt1000 are the most common. The pt100 sensor is just like a variable resistor whose resistance varies with respect to the environment temperature.

Linearity of the characteristic curve operating temperature range and response time are the same for both. There s information on rtd and prt sensors different pt100 mechanical structures temperature resistance relationship temperature coefficients accuracy classes and on many more. Shop rtds at automation direct. Air temperature sensor for indoor or outdoor use ewsa.

Pt1000 sensors nominal resistance at 0 c is 1 000ω. Enclosure contains screw terminal connections and cable bushing. 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. 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.

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. Pt100 temperature sensor pinout click the image to enlarge it pin configuration. This blog post discusses many useful and practical things to know about the pt100 sensors.

There are many types of pt100 sensors the one we use here is a two wire one. Stainless steel air sensor with 100 or 1000 ohm rtd or 4 20 milliamp output. Via transition leads the joints to the extension cable are. Pt100 sensors have a nominal resistance of 100ω at ice point 0 c.

Resistance temperature relationship of metals. Rtd sensor platinum wirewound detector element 200 c 650 c 100 ohm pt100 series check stock lead times 50 in stock for same day shipping. Traditionally the detector is built into a protecton tube closed at the sensor ending. The pt100 temperature sensors are very common sensors in the process industry.
