Input connectors for Pt100Digital ALMEMO® D7 measuring connector for Pt100 / Pt1000 temperature sensor High-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! 11/2025 • We reserve the right to make technical changes. Technical data and functions • 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.

ALMEMO® D7 Note on suitable sensors: The sensor determines the accuracy, stability, hysteresis and long-term stability of the measuring chain consisting of sensor and digital connector. For the sensor, the following must be taken into account: - The type of Pt100 sensor element determines, among other things, the achievable measurement uncertainty / stability. - The design (sensor diameter, installation of the sensor element, powdered or with thermal paste) influences the self-heating and the hysteresis for the measurement uncertainty. The self-heating must be included in the measurement uncertainty:...
