Platinum Rtd Temperature Sensor

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.

Platinum rtd temperature sensor.

Resistance temperature relationship of metals. An rtd is a passive device. The acronym rtd stands for resistance temperature detector. The electrical resistance increases as temperature rises in a known and.

The resistance vs temperature relationship is well known and is repeatable over time. This means that a rise in temperature results in an increased resistance this change of resistance is then used to detect and measure. 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 resistance vs temperature relationship is well known and is repeatable over time.

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. Their 50 c to 500 c typical operating temperature range along with their low thermal mass high vibration and thermal shock resistance makes them. 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. 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. Rtd element sensing portion of the rtd which can be made most commonly of platinum nickel or copper. An rtd resistance temperature detector is a sensor whose resistance changes as its temperature changes. The sensors can operate in the harshest conditions while experiencing minimal drift.

Typically rtds contain either platinum nickel or copper wires as these materials have a positive temperature coefficient. A resistance temperature detector operates on the principle of the change in electrical resistance in wire as a function of temperature. The relative change in resistance temperature coefficient.

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. An rtd is a sensor whose resistance changes as its temperature changes. Platinum rtds have a positive temperature coefficient. The construction is extremely robust and due to the small dimensions the sensors are offered in various housings.

The resistance increases as the temperature of the sensor increases. Learn more about resistance temperature detectors rtd s. The resistance increases as the temperature of the sensor increases.
