Temperature Sensor Rtd Thermocouple

Thermocouples are temperature sensors that use two different metals in the sensor to produce a voltage that can be read to determine the local temperature.

Temperature sensor rtd thermocouple.

Jiutian is an expert manufacturer focusing on thermocouple rtd temperature sensor designing and manufacturing since 1995. Rtds have a range from 240 to 649 c and thermocouples from zero to 1800 c. Manufactures a complete line of thermocouple elements rtd sensors thermowell elements industrial assemblies and specialty surface temperature sensors our products include multipoint temperature sensors sanitary rtds high temperature furnace thermocouples and so much more to suit a wide variety of industrial applications and oem. For example if accuracy is considered as the key performance indicator usually rtd s are better than thermocouples.

Expert thermocouple rtd temperature sensor manufacturer. Approximately 10 times more accurate. A wide temperature range approximately 200 to 850 c li good accuracy better than thermocouples li good interchangeability li long term stability. 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.

Rtds offer several advantages. Pyromation began operations in 1962 and is one of the leading manufacturers of thermocouples rtds pt100s and thermowells in north america. Mti industrial sensors is a leading manufacturer of quality thermocouples thermowells rtds gauges temperature sensors temperature transmitters pressure gauages bimetal thermometers and millions of other temperature sensors. To wrap up this video the comparison between different types of temperature sensor technologies is a multi facet task.

Thermistor vs rtd vs thermocouple comparison measuring range. A grounded thermocouple will respond nearly three times faster than a pt100 rtd. As an iso 9001 registered company advanced manufacturing firm and lean enterprise with an onsite nvlap. While both sensor types respond quickly to temperature changes thermocouples are faster.

The fastest possible temperature sensor is an exposed tip thermocouple. The right way smart sensors inc. Rtd vs thermocouple or thermistor 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.
