Input connectors for Pt100Digital ALMEMO® D7 measuring connector for Pt100 / Pt1000 temperature sensorHigh-level resolution of 0.01 K across the entire measuring range up to 850 °C Linearization of the Pt100 / Pt1000 characteristic calculated Calibration with greater accuracy by subjecting the temperature sensor to multi-point adjustment Only for latest ALMEMO® V7 measuring instruments, AlMEMO® 202-S, 204, 104, 710, 510, 809. The new ALMEMO® D7 measuring connector provides even greater precision! • The digital ALMEMO® D7 measuring connector uses its own integrated A/D converter. It provides a high-level resolution of 0.01 K across the entire measuring range up to 850 °C. Linearization of the Pt100 / Pt1000 characteristic is calculated in compliance with DIN IEC 751 (not an approximation). • The overall accuracy of the measuring operation is unaffected by the presence of an ALMEMO® V7 display device / data logger. The whole measuring chain, comprising e.g. a Pt100 / Pt1000 sensor and the connected ALMEMO® D7 measuring connector, can be calibrated end-to-end. Calibration can be performed with greater accuracy by subjecting the temperature sensor to a process of multi-point adjustment. The measuring rate is determined entirely and exclusively by the integrated A/D converter. On the ALMEMO® V7 measuring instrument all D7 measuring connectors operate in parallel at their own measuring rate. The measuring instruments very short scan cycle is determined by the measuring rates of the D7 measuring connectors - irrespective of their number. Sensor identification can be programmed with designations up to 20 characters in length. 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:...
