HMDW110 Series Overview
HMDW110 series transmitters are accurate humidity and temperature
transmitters for measurements in HVAC and cleanroom applications. The series
consists of the following models:
n HMD110/112 models for installation in ventilation ducts
n HMW110/112 models for wall installation
n HMS110/112 models for outdoor use
All models are loop-powered, with 2-wire current outputs for humidity and
temperature. HMD112, HMW112, and HMS112 are standard models. HMD110,
HMW110, and HMS110 are factory configurable models that are delivered with
customer specific output settings, including calculated humidity parameters and
special scaling of outputs.
HMDW110 series transmitters can be connected to Vaisala’s RDP100 panel
display for real-time viewing of the measurements. HMDW110 series can also
supply the operating power to the display using only the loop power from the
outputs.
