SmartFilter TC™ Multichannel Thermocouple Signal Conditioner

Dycor SmartFilter TC FilterDesigned to work in conjunction with dataTaker® data loggers, the SmartFilter TC™ Multichannel Signal Conditioner supports up to 32 channels of fully isolated thermocouples in high electrical noise environments. The SmartFilter TC™ acts as a low pass filter, allowing the thermocouple signal to be passed to the dataTaker® logger, while filtering higher frequency, higher amplitude signals that cause measurement errors.

The SmartFilter TC™ uses advanced analog and digital signal processing to filter out alternating current (AC) interference that can cause significant electrical noise in thermocouple measurements. It was designed and built for use with the dataTaker® DT8X series data loggers and the CEM20 channel expander, with the filter being wired between the CEM20 and the data logger. The filter reads the unfiltered thermocouple mV signal from the CEM20 and outputs a filtered mV signal to the data logger.
