HYGRASGARD® VFTF-MODBUS DISPLAY

Item No. 1201-6126-1200-100
EAN 4 251325 616575

Calibratable showcase humidity and temperature sensor HYGRASGARD® VFTF - Modbus
with Modbus connection, terminal box housing made of impact-resistant plastic, housing
cover with quick-locking screws, with/ without optional display.

The universal showcase sensor is used to detect various parameters in humidity
measurement. The relative humidity and temperature of the ambient air are measured.
These measurands are used to calculate various parameters internally. The Modbus can
be used to retrieve the following parameters: relative humidity [% r. H.], absolute
humidity [g/ m³], mixture ratio [g/ kg], dew point temperature [°C], enthalpy [kJ/ kg]
(ignoring atmospheric air pressure) and ambient temperature [°C].

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 showcase sensor is used in non-aggressive, dust-free environments and is specifically
designed for installation in ceilings, walls, inside showcases or display cabinets in museums,
galleries, cinemas or lecture halls or laboratories. The measuring element is contained inside
a stainless steel probe and its low height (approx. 2.5 mm) makes it barely noticeable.
