Resistance Temperature Detectors (RTD) Construction
The RTD incorporates pure metals or certain alloys that increase in resistance as temperature increases and, conversely, decrease in resistance as temperature decreases. RTDs act somewhat like an electrical transducer, converting changes in temperature to voltage signals by the measurement of resistance. The metals that are best suited for use as RTD sensors are pure, of uniform quality, stable within a given range of temperature, and able to give reproducible resistance-temperature readings. Only a few metals have the properties necessary for use in RTD elements. RTD elements are normally constructed of platinum, copper, or nickel. These metals are best suited

How Limit Switch Works ?
Presence Sensing is the act of detecting the presence or absence of an object with a contact or non-contact sensing device. The sensors then produce an electrical output signal that can be used to control equipment or processes. Limit switches are a type of sensor that detect presence and absence. Specifically, mechanical limit switches are switches that are mechanically activated, meaning that they have some sort of arm, lever, knob, plunger, etc., which is physically—or mechanically—activated by making contact with another object. As the object makes contact with the actuator of the switch, it eventually moves the actuator to its

Conductive Level Measurement Working Principle
Measurement principle The conductivity of a liquid medium may vary widely. Once the liquid reaches the fill limit determined from the installation height of the electrode, the liquid medium closes the DC free alternating current circuit between the two electrodes (or between the container wall and an electrode). A switching signal is produced from the sudden increase in current consumption. Acids, lyes and solutions containing water are conductive and are detected very well. Aggressive liquids can be detected without problems using probes made from highly-resistant materials. Combustible liquids such as fuels, oils and solvents are nonconductive and cannot be measured

U-tube Manometer with equal & unequal limb types
This is the most simple and precise device used for the measurement of pressure. It consists of a transparent tube constructed in the form of an elongated 'U', and partially filled with the manometeric fluid such as mercury. The purpose of using mercury as the manometeric fluid is that their specific gravity at various temperatures are known exactly and they dont stick to the tube. The two common types of manometers are the equal limb type and unequal limb type. Operation of Manometer : To measure the pressure of a fluid which is less dense and immersible with the manometeric
