Groundbreaking ceremony for significant growth

The office and manufacturing space alone at the new S+S location in Nuremberg will be expanded to 8,600 m² in order to meet the increasing demand for advanced sensor devices.

With Giga factory for sensors to become the #1 on the market

On a total area of over 14000 square meters, the new S+S company headquarters is being built in the north of Nuremberg.

DFF-U

HYGRASGARD® DFF-U

Item No. 1201-6131-0000-100
EAN 4 251325 616568

The calibratable humidity and temperature sensor HYGRASGARD® DFF measures
the relative humidity and temperature of air. It converts the measurands humidity and
temperature into a standard signal of 0 - 10 V or 4...20 mA, and is available with/ without
an optional display.

It is equipped with four switchable temperature ranges. Relative humidity (in % r.H.) is the
quotient of water vapour partial pressure divided by the saturation vapour pressure at the
respective gas temperature. The measuring transducers are designed for exact detection
of temperature and humidity. A digital, long-term stable sensor is used as a measuring
element for humidity and temperature measurement. Fine adjustment by the user
is possible.

The ceiling-installed sensor is used in non-aggressive, dust-free environments and is used
for installation in suspended ceilings in corridors, offices, as well as in residential and
commercial buildings. The connecting head is pluggable for quick, easy mounting.
The measuring transducer is accommodated in a separate housing.
