4 Channels, 2-28 Vrms Input, 5 kHz-10 kHz
LD3
A linear variable differential transformer (LVDT) is a type of electrical transformer/transducer used for measuring linear displacement (position). A counterpart to this device used for measuring rotary displacement is called a rotary variable differential transformer (RVDT). The RVDT is like an LVDT in that it measures a positional displacement, however, the displacement, which is still a linear proportional function, is based on rotary instead of linear positional movement.

AC Calibration Standard
1U647-001
The 1U647-001 is a low cost calibration standard used to determine if a 1U632-100 or a 1U663-100 DMU requires factory calibration. Its portability makes it ideal for field-testing. The standard generates signals that simulate the aircraft’s resolvers, rotary variable transformers (RVTs), and linear variable displacement transformers (LVDTs). The unit also generates a pulse width modulated (PWM) signal, and routes the output of an ARINC 429 source to the different DMU input channels. The calibration standard connects directly to the DMU and replaces the output signals of an active extender card. Discrete switch settings simplify testing. The unit is housed in a rugged aluminum case.
