With more than 40 years experience in the design and manufacture of LVDTs, RDP Electronics has, over the years, also been involved with significant advances in external control systems, including the widespread adoption of the 4-20mA, two-wire interface.
In recognition that a majority of controllers utilise the simple 4-20mA system, RDP now offers 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, possess great immunity to interference and only require a two-wire cable, which can be very long.
