TTUA
Humidity and temperature transmitter
for room mounting

Wall mounted room transmitters for measuring

humidity and temperature in indoor environments. • Output signal 0…10 V or Modbus
• With or without display
• Good long-term stability
• Humidity range 0…100 RH%
• Temperature range 0…50 °C

SUPPLY VOLTAGE
Function
The transmitter uses a supply voltage of max. 24 V AC
The sensor is mounted in the cover-part of the casing. The

cover is easy to detach from the back by means of snap-in
grips and detachable terminals which makes mounting
easy. Furthermore, no cables have to be disconnected, Appearance
simplifying service and replacement. The transmitter comes in a discreet white housing. The
TEMPERATURE version …-D has a LCD display showing temperature and
humidity in an alternating series.
The transmitter has a built in temperature sensor, which
gives output signal 0...10 V and has a temperature range
of 0...50 °C. In the versions ... -M the output will result Installation
in a Modbus signal. The transmitter should be mounted in a location with
good air circulation where it can be expected to give a

The transmitters have a capacitive thin-film element

which gives a signal that is proportional to the relative
humidity. The measuring signal is converted by the built-
in electronics to output signal 0...10 V (corresponding to
0…100 % RH). The sensor element has rapid response to
changes in humidity, and excellent long-term stability. The
element also has good durability in contaminated environ-
ments.
