Showcase humidity and tempe­rature sensor
HYGRASGARD® VFF / VFTF

HYGRASGARD® VFF / VFTF

The calibratable humidity and temperature sensor HYGRASGARD® VFF ⁄ VFTF 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 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.
