- Programmable input range
- High accuracy (0.02% FSR typical)
- Programmable voltage excitation per channel
- Short on any channel does not affect others
- 16-bit simultaneous sampling with three configurable output streams on each channel
- Completion resistors and classic shunt
Applications
- Bridge sensors and strain gage measurement
- Differential voltage measurement
The AXN/CHS/03U is a 3 user-slot Axon chassis, which along with the housing and backplane, includes an isolated 50W power supply for the controller and user modules.
The AXN/ADC/401 is used to condition and digitize up to eight analog channels.
The AXN/ADC/408 is a monitor for 3-phase power lines that supports variable frequency power monitoring.
AXN/ADC/404 Axon Full/Half Bridge ADC
The AXN/ADC/404 provides independent excitation for up to 12 channels and is intended for full or 1/2 bridge sensors, or for differential input measurements.
At the heart of the AXN/ADC/404 is a hard-wired state machine that oversamples all channels and digitally filters any noise above the user-programmable cutoff frequency.
This is achieved using cascaded, 15-tap FIR filters with output rate decimation, followed by a final FIR or IIR filter. If IIR filtering mode is selected, the last digital filter in the filtering chain is an 8th or 16th order (selectable) Butterworth filter. If FIR mode is selected, the last digital filter in the filtering chain is a 49-tap Kaiser window, Beta 6 filter.
There are three independently configurable output streams per channel, allowing different sample rate, cutoff, and filter type to be selected for each output stream.
All signals are sampled simultaneously. Thus, when several channels are sampled at different sampling rates, at the start of an acquisition cycle, all channels are aligned.
The AXN/ADC/404 supports programmable primary gain, voltage excitation (with compliance up to 32 mA), digital filter type as well as completion resistors, and high accuracy.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
