The resistance thermometer is also known as resistance temperature detector. By using the sensor the temperature is measured by comparing the resistance of the resistance temperature detector element with temperature. In most of the cases the RTD elements contain a length of fine coiled wire wrapped around the glass core or ceramic. The RTD elements are made up of nickel,

Based on the industry standards some combinations of alloys have become popular. Erected on the type of blend the cost convenience, availability, stability chemical properties, melting point and output thermocouples are available. Various types of thermocouples are used in various applications. Individuals have carefully chosen the thermocouple on the base of sensitivity and temperature range. Minimal sensitivity in the thermocouples

The silicon band gap temperature sensor is used in the electronic equipment. The main advantage of using this thermometer is due to the cost efficiency compared to the remaining temperature sensors. The integrated circuit present in the thermometer is low of cost. The measuring temperature depends on the bipolar junction transistor. T = Temperature measured in Kelvin = reference temperature

The pyrometer comes from the Greek word. The meaning is to measure. Pyrometer is a type of thermometer which is helpful to measure high temperatures. Various types of pyrometers are existed historically.  In the present usage, there is non-contact device that interrupts and measured the thermal radiation. This process is known as pyrometry. The temperature on the surface is measured

Mercury in glass Thermometer The mercury thermometer or mercury in glass thermometer was invented by Daniel Gabriel Fahrenheit in 1714. The mercury glass thermometer consists of a bulb and it contains mercury in it. And the tube is attached to the glass tube is of thin diameter. Compared to the bulb volume in the tube the mercury is very less.

A plastic strip thermometer or liquid crystal thermometer is a type of thermometer which contains heat sensitive liquid crystals. The liquid crystals in the plastic strip changes colour to indicate the dissimilar temperatures. Liquid crystals have the mechanical properties of a fluid, but need the visual properties of a single crystal. Change in temperature can affect the colour of a

Glass thermometer: In an indoor thermometer and outdoor thermometer, these two are based on a conventional liquid in glass thermometer. The stem present in the outdoor thermometer is connected to the bulb by a long semi rigid capillary or flexible capillary. On the stem the temperature scale is marked. At the bulb the temperature is actually measured. Ambient modifications are

Heat meter is a device used to measure the thermal energy provided by a source. In the other case, the energy should be delivered to the sink. The flow rate must be measured by the heat transfer fluid. So there is a temperature change between the outflow fluid and return legs of the system. The heat meter is mainly used

Cryometer A Cryometer is used to measure the low temperature of an object. There are different types of Cryometer. They are Thermocouples Vapour pressure thermometer Resistance thermometer Melting curve thermometer Resistance noise thermometer Magnetic thermometer Nuclear resonance thermometer Thermocouples: The thermocouples are used to measure the temperature which is about 1 K Vapour pressure thermometers The vapour pressure thermometers are
