CAUTION: Electrical Safety
Under normal circumstances, you are unlikely to suffer any real harm from the low voltages and
currents used in the OD2 Transmitter. However, the electrical connections should be made with
the power off.

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.
1.2 SPECIFICATIONS
Instrument specifications are listed in Table B1.1. These specifications are the performance stan-
dards or limits against which the instrument is tested.
1.3 SAFETY CONSIDERATIONS
Before operation, the instrument and manual, including the safety page, should be reviewed for
safety markings and instructions. These must then be followed to ensure safe operation and to
maintain the instrument in a safe condition.
1.4 INSTRUMENTS COVERED BY MANUAL
Attached to the top of this instrument is a name plate (Fig. 1.1 ), this manual only refers to instru-
ments listed in Table B1.2.
1.5 MAINTENANCE AND REPAIR
If the instrument is suspected of being unsafe, take it out of operation permanently. This is the
case when the instrument:
- shows physical damage;
- does not function anymore;
- is stressed beyond the tolerable limits (eg. during storage and transportation).
1.6 DISMANTLING THE INSTRUMENT
Before opening the instrument, disconnect it from all power sources. Refer to the Service Safety
Summary. Calibration, maintenance or repair must be performed only by trained personnel being
aware of the risks.

OD2 Transmitter will operate with most Solartron transducers having strokes up to E100mm
(E4in), 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.
