Dewesoft KRYPTON thermocouple amplifier

The Dewesoft KRYPTON range now offers an amplifier for thermocouple sensor inputs. These devices with TH-HS amplifier offer high-speed acquisition rates and channel-to-channel isolation for temperature measurements with thermocouple sensors, and universal thermocouple input for all thermocouple types: K, J, T, R, S, N, E, C and B.

The amplifier addresses the growing need for stable temperature measurements in an EMC-harsh environment, such as on the stator of an electric motor or near inverters. The amplifier doesn’t only improve upon the EMC immunity of the previous unit on the digital side but also uses a sharp analog antialiasing filter (3rd order, -3dB @ 1 kHz) and digital FIR filters to remove unwanted frequencies.

The input connector is MINI TC. Sensor break detection is provided in the software and applies physical LED indicators.

A 24-bit ADC is used with sampling rates of up to 10 kS/s per channel. This enables use in dynamically demanding applications when recording transients of temperature shocks. A higher sampling rate also enables Dewesoft filtering technology, using digital FIR filters to reduce the noise floor down to -130 dB and reach a resolution below 1 μK.
