This manual provides detailed information on the HMP260 series humidity sensors, including product description, installation, commissioning, commands, etc.
The HMP260 series includes the HMP263, HMP264 and HMP265 transmitters that measure relative humidity and temperature, and calculate dew‑point, absolute humidity, mixing ratio and wet‑bulb temperature. The devices feature two analogue outputs, RS‑232C, RS‑485/422 and digital current‑loop interfaces, and optional local display/keypad.
The manual provides guidance on proper installation (free air flow, transverse mounting, IP65 housing), commissioning, command sets for serial and keypad operation, calibration procedures, maintenance checks and technical specifications. Appendices contain wiring diagrams, safety summaries and calculation formulas.
