1. GENERAL
1.1 INTRODUCTION
The Model OD2 Transmitter is designed for use with ac inductive type LVDT displacement trans-
ducers. It has a dual function: (1) its onboard oscillator derives power from the supply and pro-
duces a sine wave carrier to drive the transducer primary winding; (2) its amplifier, demodulator
and filter circuit conditions the transducer output and a voltage-to-current converter produces
this as a dc milliamp drive. The transmitter is especially suitable where a readout is required at a
substantial distance from the transducer and for interfacing with a controller, or computer in auto-
mated manufacturing processes.
