LVDTs with 4-20mA two-wire output

Paul Boughton

With more than f40 years' experience in the design and manufacture of LVDTs, RDP Electronics has also been involved with significant advances in external control systems, including the widespread adoption of the 4-20mA, two-wire interface.

In recognition of the fact that a majority of controllers utilise the simple 4-20mA system, RDP is now offering this output option on a wide range of transducers, either directly or in conjunction with a simple external module.

RDP LVDTs with 4-20mA output offer connection simplicity, are robust against accidental damage, have good immunity to interference and only require a two-wire cable, which can be relatively long.
