What is the function of compensating leads in the platinum resistance thermometer?
Compensating leads help to reduce errors in temperature measurement by minimizing the impact of lead resistance on the overall measurement. They are made of the same material as the sensor to maintain consistency in resistance, ensuring accurate temperature readings.
Does platinum dissolve in nitric acid?
Platinum does not dissolve in nitric acid, which is why it is commonly used in jewelry and other applications that require resistance to corrosion.
What element is an inert metal often used in electrodes?
Platinum is an inert metal often used in electrodes due to its stability and resistance to corrosion. It is commonly used in medical devices, fuel cells, and laboratory equipment.
What is the material used in RTD?
The most common materials used for RTD (resistance temperature detector) sensors are platinum, nickel, and copper. Platinum is the most commonly used material due to its high accuracy and stability in a wide temperature range.
Will sodium hydroxide solution react with platinum?
Sodium hydroxide does not react with platinum under normal conditions as platinum is inert to many chemical reagents, including sodium hydroxide. Platinum is often used in chemical processes precisely because of its resistance to corrosion and reactivity.
What is platinum thermometer?
A platinum thermometer is a type of resistance thermometer that uses a platinum element as the temperature-sensing material. Platinum is often chosen for its high accuracy and stability over a wide range of temperatures, making platinum thermometers suitable for precision temperature measurement applications.
What is the function of compensating leads in the platinum resistance thermometer?
Compensating leads help to reduce errors in temperature measurement by minimizing the impact of lead resistance on the overall measurement. They are made of the same material as the sensor to maintain consistency in resistance, ensuring accurate temperature readings.
Thermometer use to measure temperature above 1250 celsius?
A thermocouple or a pyrometer is commonly used to measure temperatures above 1250 degrees Celsius. These devices are designed to withstand high temperatures and provide accurate temperature readings in such extreme conditions. It is important to select the appropriate type of thermometer that can handle the desired temperature range for accurate results.
What are the industrial used of platinum?
These metals are used as emission catalysts for automobiles and in electronics and glass applications. Platinum is highly valued for its corrosion resistance and catalytic activity.
Temperature can be measured by what?
Temperature is measured by a liquid in glass thermometer in most cases. Other instruments such as thermocouples, resistance or digital thermometers are used for more extreme conditions.
Does platinum dissolve in nitric acid?
Platinum does not dissolve in nitric acid, which is why it is commonly used in jewelry and other applications that require resistance to corrosion.
Why you use rheostat of 15ohm resistance in melde's experiment?
A rheostat with a 15 ohm resistance is used in Melde's experiment to control the amount of current passing through the system. By adjusting the resistance of the rheostat, the frequency of vibration of the standing wave on the string can be varied. This allows for the different modes of vibration to be studied in the experiment.
Resistance thermometer purpose of the device?
they are devices used to measure the temperature, applying the temperature to RTD element. they are sensory devices.
What tool is used to measure the current room temperature?
A thermometer is commonly used to measure the current room temperature. This can be either a traditional mercury thermometer, a digital thermometer, or a smart thermostat that displays the temperature on a screen.
What element is an inert metal often used in electrodes?
Platinum is an inert metal often used in electrodes due to its stability and resistance to corrosion. It is commonly used in medical devices, fuel cells, and laboratory equipment.
What is used to measure temperature?
Temperature is usually measured via expansion/contraction of a liquid (liquid thermometer), differences in expansion/contraction of two metals (bi-metallic strip thermometer), changes in electrical resistance (thermistor or thermocouple) or radiant energy (for example: a pyrometer)
What solid is commonly used as an inactive electrode in electrochemical cells?
Platinum is commonly used as an inactive electrode in electrochemical cells due to its inert nature and resistance to corrosion during the electrochemical reactions.
