Displacement Input
The PXI Displacement Input Module supports 4-, 5-, and 6-wire AC linear variable differential transformer (LVDT) and AC rotary variable differential transformer (RVDT) measurements. The module simultaneously samples each analog input and sets the excitation frequency and voltage for each channel independently. You can set different timing, triggering, and sampling modes for each channel independently. Diagnostic features include self-calibration, overcurrent detection, and open coil detection.The PXI Displacement Input Module includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.

Linear Variable Differential Transformers (LVDTs)
-
Whilst there are several ways to measure displacement, the Linear Variable Differential Transformer (LVDT) remains a popular transducer in most industrial applications. LVDTs initially were used as a means of taking dimensional readings in laboratories. They gained popularity in a wide variety of industrial monitoring and control applications, and whilst an LVDT is used to measure displacement the technology can be employed within other transducer types.

LD4
-
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.

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.
