We see from your search that you're looking for information on the term "LVDT (Linear Variable Displacement Transducer)",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release DROs improve rotary table efficiency from
ACI (UK), which we summarised at the time by saying "The use of digital readout systems is playing a key role in enabling a tooling manufacturer to maintain its worldwide reputation for the supply of high precision rotary tables".
A few weeks before,
we featured the news release 'Go/no-go' component inspection made easy from
ACI (UK): "Measurement and control specialist ACI (UK) has made available Metronics' Gage-Chek, a 'go/no-go' gauge for checking even the most complex components".
In June 2007, we covered the news from GTMA
- take a look at DRO and CNC systems firm joins GTMA
which says: "Regarding the UK's GTMA as 'one of our most proactive trade associations', measurement and control company, ACI (UK), has taken up membership of the Association".
Take a look also at the news release from RDP Electronics, Loop powered transducer ideal for position sensors,
as well as LVDT range expanded from Applied Measurements,
and Linear variable differential transformer products from Monitran.
