The Solartron Metrology OD2 Transmitter is designed for use with ac inductive type LVDT displacement transducers.

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.

Key features

Two wire 4-20 mA signal conditioner
Low noise susceptibility
Suitable for long ranges
IP65 protection class

OD2 Transmitter will operate with most Solartron transducers having strokes up to E100 mm (E4 in), in particular with the SM, AC, AX, AT and some of the MACH 1’s. Switches on the printed circuit card are used to set up the transmitter for a specific transducer type and onboard Span/ Zero controls are provided for calibration purposes.
