LDTs have many attractive features, which have made them indispensable in today's measurement and control applications. Their noncontact measurement effectively reduces wear, which improves operational life and reduces downtime. Made with high precision, thus now you can easily perform all your repeatable measurements in their various industrial applications without compromising the accuracy. The actual real time feed back is the ability for the system to to instantly respond to positional changes such as having an automated system or precision quality control based on the sensors. Their robustness and ability to withstand the effects of environmental aspects such as Electromagnetic Interference (EMI), shock and temperature variations make them reliable to operate in various conditions. Digital, Analog and Fieldbus interfaces, makes them to be integrted with control systems and data recording devices with no problem. The lack of moving parts in addition to the designs of most modern ones make them virtually maintenance free and generally more reliable and long lasting than any other type. These transducers have high resolution and on occasion are capable of micro accuracy and stability over long periods of time. Thanks to their small size and versatile mounting options, they are particularly suited for space restricted applications. The instruments are low maintenance and need only be calibrated occasionally. They enable the possibility of scaling in a wide range of measurement from fraction of millimeter to several meters, so that they can be applied to different applications. The fast response time and high sampling rate make it possible to better monitor rapid position changes, required in the case of dynamic control systems. In addition, they are energy efficient and consume low power, which cuts down on operating costs and environmental impact.
