Q-Series Room Relative Humidity and
Relative Humidity & Temperature
Sensors
Item Number 129-505, Rev FA Page 1 of 2
Product Description
The Q-Series Room Relative Humidity and Relative
Humidity & Temperature Sensors monitor and
transmit changes in humidity and temperature to the
building control systems. These units are especially
suited for applications where precise, stable
humidity sensing is required.
These combined relative humidity and temperature
units have a 0 to 10V or 4 to 20 mA output signal for
the humidity output and a 0 to 10V, 4 to 20 mA or
passive resistive sensor element for the temperature
output.

space above and below for proper air flow and
access.
Away from drafts caused by doors, windows,
outside walls, air registers, pipes, return air
plenums, etc.
Away from heat sources, such as strong lights,
fireplaces, direct sunlight, etc.
On an inside wall (preferably), about 5 feet
(1.5 m) above the finished floor.
