P104 LVDT/RVDT Measurement Board
73LD4
-
NAI’s 73LD4 is a PC104-compliant LVDT/RVDT Measurement Board with six separate transformer-isolated channels. The channels can incorporate up to six programmable LVDT/RVDT-to-Digital Tracking Converters in a stack-through module. Each channel is programmable for 2-, 3-, or 4-wire inputs that automatically range between 2.0 volts and 28 volts, so there is no need to purchase multiple boards set for specific inputs. Operating frequency between 360 Hz and 10 kHz can be specified. Each channel also produces differential incremental encoder (A & B) outputs with programmable resolution and a zero-degree marker pulse.

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.

Digital LVDT sensor ZET 7111-L
-
ZET 7111-L is a digital LVDT displacement sensor. It requires no special adjustment and starts measuring right after power is on. Displacement measured values are transferred in digital form via CAN interface. The LVDT digital sensor consists of a primary transducer (LVDT sensor) and a measuring element (ZET 7111-L unit). The LVDT sensor converts meaured object (to which it is mechanically connected) linear displacement into electric signal to be further transferred into displacement values by the measurement module.

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.

Linear Variable Differential Transformer (LVDT) and Rotary Variable Differential Transformer (RVDT) are transformer-type voltage/current transducers that convert a linear/rotary movement of a core/shaft to a multi-wire differential AC electrical signal. Both deliver signals linearly proportional to the position of a shaft (magnetic induction core). An LVDT/RVDT simulator is used to convert digital positional commands to corresponding AC signals.
