Showcase humidity and temperature sensor
HYGRASGARD® VFTF - Modbus
Calibratable HYGRASGARD® VFTF - Modbus
showcase humidity and temperature transmitter with Modbus connection, terminal box enclosure made of impact resistant plastic, enclosure cover with quick-locking screws, with/without optional display.
The universal showcase transducer serves to detect various parametres in humidity measuring. Measurands include relative humidity and ambient air temperature.
These measurands are used to calculate various parametres internally. The Modbus device can be used to retrieve the following parametres: 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 provides precise detection of temperature and humidity.
A digital, long-term stable sensor is used as a measuring element for humidity and temperature Fine adjustment by the user is possible.

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