This document is the instruction manual of HMD70U/Y temperature and humidity sensor.
This manual describes the mechanical mounting, electrical connections, and optional current‑loop module for the HMD70U/Y humidity and temperature transmitters. It includes detailed diagrams for mounting holes, cable shielding, and the recommended use of a pressure‑seal to ensure electromagnetic compatibility.
The document also covers disassembly and re‑assembly of the sensor head, calibration procedures using the portable HMI41 indicator, replacement of the HUMICAP® sensor and filter, and provides a full technical data sheet with measurement ranges, accuracy, response time, and power‑supply options. This manual is written in French.
| Humidity measurement range | 0…100 %HR |
|---|---|
| Temperature measurement range (model Y) | -20…480 °C |
| Response time (90%) at 20 °C | 15 s with filter membrane |
Calibration should be verified once per year, depending on operating conditions and required measurement accuracy.
