Rtd Sensor Temperature Range

The relative change in resistance temperature coefficient.

Rtd sensor temperature range.

Resistance temperature relationship of metals. For example a class a sensor equipped with a coiled rtd element must maintain the specified tolerance from 100 450 c. By selecting the proper elements and protective sheathing rtds can operate in a temperature range of 200 to 650 c 328 to 1202 f. This depends on the material of the wire used in the sensor.

Rtds offer several advantages. Why use an rtd instead of a thermocouple or thermistor sensor. The din standard specifies a base resistance of 100 ohms at 0 c and a temperature coefficient of 00385 ohm ohm c. The curve describes the resistance vs temperature characteristics of a platinum 100 ohm sensor the standardized tolerances and the measurable temperature range.

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. For platinum is used the range is up to 660 0 c. Each type of temperature sensor has a particular set of conditions for which it is best suited. Different combinations of metals can be used in building the thermocouples to provide different calibrations with different temperature ranges and sensor characteristics.

Pyromation manufactures resistance temperature detectors and resistance thermometers for many industry applications. 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. 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.

Nickel is suitable for temperatures below 300 0 c. When operated outside this temperature range the sensor accuracy might default to class b. A wide temperature range approximately 200 to 850 c good accuracy better than thermocouples good interchangeability long term stability.
