Input connectors for NTCDigital ALMEMO® D6 measuring connector for temperature sensors NTCHigh levels of precision and resolution 0.001 K across measuring range -20 to +65 °C. Linearization of the NTC characteristic - calculated using Galway Steinhart coefficients. Increased measured value accuracy - thanks to multi-point adjustment of the NTC sensor during calibration. For all ALMEMO® V6 and V7 measuring instruments, including ALMEMO® 2490 and ALMEMO® 202-S. Technical data and functions • The digital ALMEMO® D6 measuring connector uses its own integrated A/D converter. Linearization of the NTC characteristic is calculated using the Galway Steinhart coefficients (not an approximation). Across measuring range -20 to +65 °C this produces the very high resolution of 0.001 K. • The digital temperature sensor reaches this high level of precision irrespective of any extension cables used and of any processing in the ALMEMO® display device / data logger. Overall accuracy is determined exclusively by the NTC sensor and the ALMEMO® D6 measuring connector. This increased measured value accuracy is achieved by subjecting the NTC sensor to multi-point adjustment during calibration. With the ALMEMO® D6 measuring plug, customer-specific NTC sensors can be connected to the ALMEMO® system after the corresponding Steinhart-Hart coefficients have been configured via the sensor menu. When using own sensors no additional adjustment of the connector is necessary. Sensor type Measuring input 11/2025 • We reserve the right to make technical changes.
