Platinum Rtd Temperature Sensor

An rtd is a sensor whose resistance changes as its temperature changes.

Platinum rtd temperature sensor.

It does not produce an output on its. Platinum rtds resistance temperature detectors are sensing elements that are made of pure platinum wire coil wire wound encapsulated in ceramic or glass or a thin film platinum deposited on a ceramic substrate. The construction is extremely robust and due to the small dimensions the sensors are offered in various housings. 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.

The relative change in resistance temperature coefficient. Temperature sensor rtds littelfuse leaded resistance temperature detectors rtds exhibit a nearly linear temperature resistance curve as well as high accuracy over a very wide temperature range. 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.

Platinum the ist ag platinum rtd temperature sensors are developed with the highest quality materials and cover a wide operating temperature range of 200 c to 1000 c. Typically rtds contain either platinum nickel or copper wires as these materials have a positive temperature coefficient. An rtd is a passive device. Their 50 c to 500 c typical operating temperature range along with their low thermal mass high vibration and thermal shock resistance makes them.

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. The resistance increases as the temperature of the sensor increases. What is a platinum rtd. This means that a rise in temperature results in an increased resistance this change of resistance is then used to detect and measure.

A resistance temperature detector operates on the principle of the change in electrical resistance in wire as a function of temperature. Rtd element sensing portion of the rtd which can be made most commonly of platinum nickel or copper. Resistance temperature relationship of metals. 3328 for precision temperature sensing nothing beats a platinum rtd.

The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. The resistance vs temperature relationship is well known and is repeatable over time. The sensors can operate in the harshest conditions while experiencing minimal drift.

An rtd resistance temperature detector is a sensor whose resistance changes as its temperature changes. Resistance temperature detectors rtds are temperature sensors that contain a resistor that changes resistance value as its temperature changes basically a kind of thermistor in this resistance sensor. The electrical resistance increases as temperature rises in a known and.
