Description

Showcase humidity and temperature sensor HYGRASGARD® VFF / VFTF
The calibratable HYGRASGARD® VFF / VFTF humidity and temperature transmitter measures the relative humidity and temperature of air. It converts the measurands of humidity and temperature into a standard signal of 0-10 V or 4...20 mA, and is available with/without an optional display. The sensor device supports 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 transducer provides precise detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
The showcase sensor device is used in non-aggressive, dust-free environments and is specifically designed for installation in ceilings and walls as well as 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.
