LVDT sensors still perfect after over 25 years
A
RDP Electronics product story
Edited by the Engineeringtalk editorial team
Oct 2, 2001
When Hydraulic Presses (UK) returned the 1974 LVDT sensors which had been fitted as original equipment to the RDP Electronics factory for recalibration, they were in perfect order!
Hydraulic Presses (UK) of Cannock, West Midlands, has been in the business of repairing and refurbishing industrial presses for over thirty years.
They know the importance of long-term reliability and so do their customers.
Hydraulic Presses is also an RDP customer, replacing pre-used machines' sensors with new RDP versions as a matter of course.
One recent project involved the complete refurbishment of a press which had been in constant use from the time of its initial installation in 1974.
Dale Chambers takes up the story, "We noticed that the LVDT sensors fitted as original equipment were made by RDP Electronics, so we returned them to the factory for recalibration." RDP regularly provides sensor recalibration and certification, but everyone was astounded by the results of this request.
As Fred Thornycroft of RDP explained, "Imagine our delight when we found the 1974 transducers to be in perfect working order after nearly three decades of continuous use.".
