E74 In-Line Signal Conditioning Amplifiers

The E74 series amplifiers are designed to factory fit in the cable of any RDP Industrial series LVDT. They convert the LVDT into a dc to dc or 4-20mA output depending upon which version is used. Many LVDT transducers from our stock are as standard compatible with the E74 series which means that in many cases we can quickly provide dc to dc or 4-20mA output transducers.

For a voltage output consider the E747V, for 4-20mA consider the E748C.
