Digital ALMEMO® D7 measuring connector for thermocouple sensors of type K, N, T, J, R, S, B, E Measure dynamic temperature changes with up to 100 measurement operations per second. One single connector for different thermocouple types (programmable). Optimal linearization accuracy of the thermocouple characteristic by calculation methods as per the DIN IEC 584. Increased accuracy thanks to multi-point adjustment of the thermocouple sensor during calibration. For current measuring instruments ALMEMO® V7, ALMEMO® 202-S, 204, 104, 710, 510, 809. Technical data and functions • The digital ALMEMO® D7 measuring connector for thermocouples can be used for a variety of thermocouple types. Once connected, the thermocouple type is programmed via the ALMEMO® V7 measuring instrument. • The range for thermocouple type E. For use at lowest temperatures. • The thermocouple is connected via 2 screw terminals integrated in the measuring connector. Every measuring connector has an integrated temperature sensor directly in the screw terminals for measurement and automatic compensation of the cold junction temperature. • The input of the ALMEMO® D7 measuring connector is galvanically isolated from the ALMEMO® V7 measuring instrument. Therefore the connected thermocouple sensor is galvanically isolated from the other connected ALMEMO® sensors as well. • The digital ALMEMO® D7 measuring connector operates with its own integrated A/D converter. The linearization of the thermocouple characteristic is calculated using method in compliance with DIN IEC 584 (not an approximation). • For measuring dynamic temperature changes, the ALMEMO® D7 measuring connector operates at a fast conversion rate. The measuring rate is determined exclusively by the integrated A/D converter. • On the ALMEMO® V7 measuring instrument all D7 measuring connectors operate in parallel - each at its own measuring rate. The measuring instrument's very short scan cycle is determined by the measuring rates of the d7 measuring connectors - nearly irrespective of their number. The ALMEMO® V7 measuring instrument saves the measured values; the measuring software WinControl displays them graphically. • The overall accuracy of the measuring operation is unaffected by the presence of an ALMEMO® V7 display device / data logger. In case the measuring chain - consisting of a thermocouple sensor and the connected ALMEMO® D7 measuring connector - is calibrated, the measuring chain can be connected to any ALMEMO® V7 measuring device without any additional measuring uncertainties. • At constant ambient conditions, an increased system accuracy is achieved by calibrating the thermocouple sensor using multipoint adjustment. • To designate a sensor it is possible to program comments with up to 20 characters. 11/2025 • We reserve the right to make technical changes.

The self-heating must be included in the measurement uncertainty: If the self-heating is NOT known for the sensor design at hand, a lump sum must be charged. Example: For a sufficiently long sheath element, an amount of 17 mK is recommended. In comparison: For the Ahlborn precision probe FPA923/FPD723 the self-heating was determined and is included in the measurement uncertainty with typ. 2 mK. The hysteresis must be described in addition to the measurement uncertainty: If the hysteresis is not determined, a lump sum of up to 0.2 % of the span is recommended in international regulations. Example:...
