What material is used in making thermistors?
Thermistors are typically made from metal oxides such as manganese, nickel, cobalt, or iron. These metal oxides are mixed with a ceramic binder and then sintered to form a compact thermistor element.
What do thermisters do?
Thermistors are temperature-sensitive resistors that change resistance with temperature. They are commonly used in electronic devices for temperature measurement and control. Their resistance can be used to calculate the temperature of the surrounding environment.
Can we use a bourdon gauge for measuring or sensing temperature?
No, bourdon gauges are typically used for measuring pressure, not temperature. For temperature measurement, instruments such as thermocouples, thermistors, or RTDs are commonly used.
How do thermistors work in clothes dryers?
Thermistors in clothes dryers work by sensing the temperature inside the dryer drum. They change their electrical resistance with temperature variations, which is then used by the dryer's control system to regulate the heating element. This helps maintain a consistent temperature during the drying cycle.
What is the difference between ntc and ptc?
NTC is resistance decreases as the temperature increases. NTC are made up of metal oxides from elements such as iron, copper, manganese, nickel and titanium. NTC are very reliable and can operate accurately at relatively high temperatures. NTC are uses in thermostats, ovens, engines and laboratory, industrial and manufacturing processes. PTC resistance increases as the temperature increases. PTC is many applications that benefit from their temperature measuring capabilities. PTC is semi conductive resistors made from polymers or polycrystalline ceramic materials. PTC are used in apparatuses such as motors and self-regulating heaters, and in time-delay, liquid level and air-flow equipment. PTC will offer the amount of resistance required to regulate temperatures or limit currents, therefore protecting the application from damage.
Why are thermistors used?
thermistors change value as thermal units increases or decreases . that can be used to shut down items that unnecessarily overheat
How are thermistors used in computer fans?
Thermistors change their properties with temperature, so they can be used to run a fan only when it's hot.

Is Thermistor ohmic or non-ohmic?
no.....thermistors are not ohmic.
What is principle of thermistor?
The thermistors are resistors whose resistance changes with the temperature. While for most of the metals the resistance increases with temperature, the thermistors respond negatively to the temperature and their resistance decreases with the increase in temperature. Since the resistance of thermistors is dependent on the temperature, they can be connected in the electrical circuit to measure the temperature of the body.
In one high voltage electric motor installed in your water works ten thermistors were used why?
because tamrat samarjini is in the initial form

What has the author James K Luers written?
James K Luers has written: 'Test and development of inflatable spheres instrumented with miniaturized thermistors, accelerometers and pressure transducers' -- subject(s): Balloons, Thermistors, Accelerometers, Transducers
What are the characteristics of a thermistor?
Thermistors are semiconducting devices whose electrical resistance is sensitive to the temperature (which is derived from the two words thermal and resistor). The resistance of a thermistor decreases approximately exponentially with the increasing of temperature. Therefore it is possible to determine the temperature by measuring the resistance across the thermistor. Thermistors are used in various fields such as self regulating heating elements, current limiters and temperature sensors etc.The thermistors are also very robust. And they could not be confused with RTDs (resistance temperature detectors), as the prior is made of semiconductors and the latter from pure metals. Also where RTDs are effective in a massive temperature range where thermistors work in a limited temperature range such as 180 K to 400 K, but with a higher precision.

What does a thermistor do that makes it different from a thermocouple?
a thermistor is a temperature sensitive resistor - to measure temperature you must measure its resistance and convert that resistance to equivalent temperaturea thermocouple is a temperature sensitive voltage source(i.e. battery) - to measure temperature you must measure the voltage across it and a reference thermocouple at a known constant temperature connected in series with it and convert that voltage to equivalent temperatureNote: Thermistors do not require reference thermistors, thermocouples do require reference thermocouples at a known constant temperature. Thermocouples are more linear than thermistors, making them easier to read accurately. Thermocouples are available that are far more sensitive to small changes in temperature than thermistors.
