HMD60UO/YO Outdoor Humidity and

Temperature Transmitter & Solar Radiation Shield

Stable performance in

demanding outside

environments

The duct-mo unt Vaisala HUMICAP®

Humi dity and Temperature

Transmitters HMD60UO and

HMD60YO utilize Vaisala HUMICAP®

Sensor. The Vaisala HUMICAP® Sensor

is known for its excellent reliability, long-

term stability, and reliable operation in

humidity measurement. In addition, the

sensors are insensitive to dust and most

chemicals, and are not damaged by

condensation. The transmitters feature

two wire connections that make

retrofitting, upgrading and installations

easy.

Fast, on-site calibration

The accuracy of the transmitters is easy

to check by using Vaisa la HUMICAP®

Hand-Held Humidity Meter HM70. The

calibration can be done in seconds with

a single potentiometer – without

disturbing the operation, thus ensuring

accuracy and saving hours of

maintenance time.

Shield protects sensor

The maintenance-free, 12 plate Vaisala

Solar radiation Shield DTR503B is

naturally ventilated, and protects the

sensors from scattered, as well as, direct

solar radiation and rain.

The plates are composed of a special

plastic material that offers excellent

thermal characteristics and UV

stabilized construction. The white outer

surface reflects radiation, while the

black inside absorbs accumulated heat,

resulting in more accurate

measurement.

Easy-to-install

The easy-to-install DTR503B is suitable

for a wide range of applications. It can be

mounted on a vertical pole, horizontal

beam or flat surface.

Vaisala HUMICAP® Humidity and

Temperature Trasnmitter HMD60YO,

combined with Vaisala Solar Radiation

Shield DTR503B is easy to install and ideal

for outdoor applications.

HMD70UO/YO

Versatile alternatives to the HMD60UO/

YO transmitters for outdoor applications

are the HMD70UO/YO transmitters.

These instruments feature selectable

output signals of 0…1V, 0…5V, or

0…10V or 0…20mA. Powered by either

AC or DC voltage, they are available

with relative humidity only, or relative

humidity and temperature sensors.

They are also equipped with the

radiation/precipitation shield.
