Air Quality Sensors
Energy-savings and superior room quality and comfort in an easy-to-install design
Studies indicate demand-controlled ventilation offers energy savings of up to 70% by
ensuring constant levels of indoor air quality and low operating costs. With Siemens
sensors, optimized indoor air quality and maximized energy savings are achieved by
measuring CO2 and VOC (Volatile Organic Compounds) and implementing demandcontrolled ventilation strategies.
Like all Siemens sensors with active output signals, the indoor air quality range has a
built-in self-monitoring capability for all measuring variables. The non-dispersive infrared
CO2 sensor experiences less than 1% drift per year for the first two years of operation and
negligible drift thereafter, so no calibration is necessary. In addition, the sensors can be
switched to a special service mode, offering additional convenience for project
development and commissioning.
These sophisticated sensors are housed in an aesthetically appealing modular housing to
meet the specifying recommendation of architects and eliminate the need to install
multiple room sensors close to each other.

Fast, secure, and cost-efficient
installation, this line utilizes a
true duct housing, eliminating
the need for a mounting kit
or aspiration box. An
adjustable immersion depth
accommodates all mounting
situations. No alignment with
the flow direction is required —
there’s no sensitivity to air from
outside the air duct. Since two
completely separate
compartments are used for
the measurement modules and
the connection terminals, the
measurement cannot be
falsified by air leakage. Liquid

local visual and numeric information to the occupant in the

Pressure Sensors
Covers the entire spectrum of HVAC applications with accuracy and stability
Siemens covers the range of pressure measurement requirements with sensors that
measure very low to high pressures in liquids, gases, water, refrigerants, and air.
Versions offer either a 0 to 10 Vdc or 4 to 20 mA analog output that is compatible with all
energy management systems. Measurement cells are matched precisely to the pressure
range, further enhancing measurement accuracy and eliminating the need for
temperature or pressure calibration.
The individually laser-adjusted pressure difference for air and non-aggressive gases utilizes
a patented ceramic lever system. This enables highly accurate pressure measurement that
remains stable over a long period, even in highly dynamic processes and through frequent
operating cycles.

Specialty Sensors
Cutting-edge solutions to meet emerging needs and assist in obtaining LEED credits.
Perfect for retrofit or new construction projects, these interchangeable sensors integrate
with any building management system. Through precise control and monitoring, they will
help ensure your building meets the demands of today and tomorrow. Rely on them to
deliver savings on operating costs and count on Siemens expertise for assistance in
meeting energy efficient control strategies and Green initiatives.
Solar Impact Sensors can be used when solar compensation is necessary for buildings or
building sections with large window areas that are subjected to strong solar radiation,
especially in installations where thermostatic radiator valves cannot be used.
Liquid Flow Switches are used to monitor the flow of fluids in hydraulic systems,
especially in refrigeration and heat pumps, and are for use with condensers, boilers,
and heat exchangers.

Air Velocity Sensor
The sensor is used to control
the air velocity to a constant
value, or to balance out
pressure fluctuations (supply or
extract air control). Using a
special thin-film sensing
element, the sensor operates
largely independently of the
direction of flow and is nearly
insensitive to any kind of dirt in
the air flow.

Flow switches detect the flow
of the medium to be monitored
by means of a paddle. If the
flow velocity in the piping falls
below the adjusted switch-off
value, the paddle in the
QVE1900U model actuates a
micro-switch with a dry contact
(SPDT), which closes the
contact. In the QVE1901U
model, the switching is
achieved through two opposite
magnets and a reed contact.

Used as a demand sensor in
facilities where compensation
of solar radiation is required or
desired. To determine the
impact of solar radiation, the
sensor uses a solar cell that
acquires the level of radiation.
