Description
Duct humidity and temperature sensor
HYGRASGARD® KFF-SD
Calibratable HYGRASGARD® KFF - SD / KFTF - SD duct humidity/temperature sensor (±2.0%), with plastic sinter filter (metal sinter filter optional), housing made of impact resistant plastic with snap-on cover.
The transmitter measures relative humidity and/or air temperature and converts the measurands into a standard signal of 0-10 V or 4...20 mA. It supports four switchable temperature ranges and is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and cleanroom engineering. The measuring transducer provides precise detection of humidity. A digital long-term stable sensor is used as measuring element for humidity. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
