2 PRODUCT OVERVIEW
HMDW110 Series Overview
HMDW110 series transmitters are accurate humidity and temperature transmitters for measurements in HVAC and cleanroom applications. The series consists ofthe following models:
nHMD110/112 models for installation in ventilation ducts
nHMW110/112 models for wall installation
nHMS110/112 models for outdoor use
All models are loop-powered,with 2-wire currentoutputs for humidity and temperature. HMD112,HMW112,and HMS112 are standard models. HMD110, HMW110,and HMS110 are factory configurable models thatare delivered with customer specific outputsettings,including calculated humidity parameters and special scaling ofoutputs.
HMDW110 series transmitters can be connected to Vaisala’s RDP100 panel display for real-time viewing ofthe measurements. HMDW110 series can also supply the operating power to the display using only the loop power from the outputs.

2Product Overview
Output Parameters Explained
HMDW110 series transmitters offer several outputparameters. Relative humidity (RH) and temperature (T) are the measured parameters,the others are calculated based on RH and T.

2Product Overview
Analog Output Overrange Behavior
Analog outputs ofthe HMDW100 series transmitters have a defined behavior when the values measured by the transmitter are outside the scaled analog outputrange:
nOutputis clipped atthe end ofthe scaled outputrange.
nYou can allow the outputexceed the scaled range by 10% with the aover serial command.
nOutputis setto error state (default3.6 mA) ifan error is active (for example, due to sensor damage). You can change the error state using the aerr command.
For configuration ofthe analog outputs using serial commands,see section Analog outputon page 33.

3Installation
3 INSTALLATION
Selecting Location
When mounting ductmodel transmitters:
nAvoid installing in a location where condensation may fall on the sensor inside the duct.
nPosition the sensor in the center ofthe duct.
nSelecta site where the transmitter can be installed horizontally,onto the side ofthe duct. Do notpointthe probe downward,as this will make condensation run down to the sensor.
When mounting wall model transmitters:
nSelecta location thatrepresents well the area ofinterest.
nDo notinstall on the ceiling.
nAvoid placing the transmitter near heatand moisture sources,close to the discharge ofthe supply air ducts,and in directsunlight.
When mounting outdoor transmitters:
nInstall in a location with a good airflow around the transmitter.
nAvoid placing the transmitter near windows,air conditioning units,or other heatand moisture sources such as cooling towers.
nInstall the transmitter atleast2.5 m above ground level.
