LVDT Displacement Transducers

Accurate displacement/position measurement using the Linear Variable Differential Transformer principle making it the most robust and reliable position sensor type available! The key strength is no electrical contact across the transducer position sensing element meaning��clean data,��infinite resolution��and��long life. Available in a variety of mechanical configurations. Depending on your application and environment, we have both AC LVDTs with external signal conditioning and DC to DC units which have internal signal conditioning that are easy to use and set-up with voltage or 2-wire 4-20ma outputs.


Din Rail and in-line modules compatible with RDP���s LVDTs and those from most other LVDT manufactures as well as models to work with a wide selection of strain gage based sensors. DC and AC powered versions and packages to fit all environments.

Digital Display Meters

Analog amplifiers with panel meter and microprocessor based units with a very wide range of gain adjustment ensures that our amplifiers are compatible with the vast majority of LVDT and strain gauge sensors available from most manufacturers. The E725 amplifier unit also has a serial output and limit trips with optional relays. Features such as auto-zero and MAX, MIN and TIR store are features which are also available with most versions of this unit.

Standard Options and Custom Engineered Units

With over 50 years of experience designing and manufacturing LVDTs and other types of linear position transducers we can offer a solution from our vast knowledge base to meet your application requirements. If a standard model is not suitable for your application, take advantage of our expertise and��call us at 1-800-334-5838 to discuss your special needs��with one of our application engineers and we will��design a custom solution.
