We know that the resistance of metallic conductors increases with temperature. Thermal sensors using this property of metallic conductors are called Resistance Temperature Detector(RTD). Construction of RTD The resistance temperature detector is constructed by wounding the resistance wire on a mica base. The wire is wound like a helical coil on the support to reduce […]

Temperature sensors are devices used to measure temperature that is generated by a system. It allows us to detect any physical change to that temperature by producing some output. Classification of Temperature Sensors Different types of Temperature sensors are available depending upon their applications. Two basic physical types of Temperature Sensors are Contact Temperature Sensors.

A capacitive transducer is a passive transducer that works on the principle of variable capacitances. It is used to measure physical quantities such as displacement, pressure, etc. Construction of capacitive transducer A capacitive transducer contains two conducting parallel metal plates separated by a dielectric medium. Working Principle of capacitive transducer The capacitance between these two

RVDT (Rotary Variable Differential Transformer) is a passive transducer, that works on the principle of mutual induction. It is used to measure the angular displacement. The design of RVDT is similar to LVDT, except for the design of the core. Read More: LVDT Construction,Principle and Advantages. Construction of RVDT RVDT consists of one primary coil

LVDT (Linear Variable Differential Transformer) is a passive transducer, that works on the principle of mutual induction and can be used to measure displacement, pressure, and force. Construction of LVDT LVDT consists of one primary coil and two secondary coils wounded on a cylindrical core. The core is made up of a ferromagnetic material such
