Long stroke displacement measurement
transducers
Providing a simple solution to displacement measurement are the RDP series of DCTH long stroke transducers
Providing a simple solution to displacement measurement are the RDP series of DCTH long stroke transducers With linear ranges from 25mm to 940mm, the DCTH can be ordered with a choice of 'free' armature, 'captive guided' armature and 'spring activated' armature types

Capacitive technique for rotary displacement
The RCDT rotary displacement sensor provides a high accuracy, no friction solution to accurate rotational measurement of a shaft, through application of patented capacitive, non-contact techniques
Because high quality signal conditioning electronics are fully integrated into each transducer, they provide an 'easy-to-apply' device that can be operated from either a single or dual supply from 20V dc to 40V dc with +/-5V or 0 to 10V output, or with a 4-20mA output option.
Suitable for measurement where there may be many millions of cycles or very high-speed movement, the DCTH series are extremely robust.
Using the LVDT principle they readily suit applications where long-term reliability and continuing accuracy of measurement is important.
The method is not only well suited to 'fit and forget' situations, but due to the absolute nature of the output is particularly appropriate for use in closed loop systems.
Where information needs to be transmitted, noise-free over long distances, then the RDP long stroke linear displacement transducers can provide a very cost effective solution.
Full specifications and options for use in harsh environments can be found on the RDP web site. Request a free brochure from RDP Electronics ...
