KAD/TDC/102 15 channel thermocouple ADC
The KAD/TDC/102 is used to condition and digitize up to fifteen thermocouple channels and three channels of module junction temperature. Each thermocouple channel can be configured separately for use with a wide range of thermocouple types.
Together, the KAD/TDC/102 and the CON/KAD/010 connector use the preconfigured module junction temperature channels 0 and 2, to perform linearization and cold junction compensation for each thermocouple channel. At the heart of the KAD/TDC/102 is a hard-wired state machine that oversamples all channels at a rate up to 50 ksps and digitally filters any noise above the user-programmable cutoff frequency.
This is achieved using cascaded, half-band, Finite-Impulse-Response (FIR) filters followed by an 8th order Butterworth Infinite-Impulse-Response (IIR) filter with a default cutoff point set at one-quarter of the sampling frequency (fc = fs/4). All signals are sampled simultaneously. When several channels are sampled at different sampling rates, at the start of an acquisition cycle, all channels are aligned.
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.
