HYGRASGARD® KFTF-U

Item No. 1201-3111-1000-029
EAN 4 251325 610269

Calibratable duct humidity-/ temperature sensor HYGRASGARD® KFF - SD/ KFTF - SD (± 2.0%), with plastic sinter filter (optional metal sinter filter), housing made from impact-resistant plastic with snap-on lid.

Calibratable duct humidity/ temperature sensor HYGRASGARD® KFF/ KFTF (± 2.0%) or KFF - 20/ KFTF - 20 (± 1.8%), with plastic sinter filter (optional metal sinter filter), housing made from impact-resistant plastic with quick-locking screws with/ without optional display.

It measures the relative humidity and/ or the temperature of the air and converts the measurands into a standard signal of 0 - 10 V or 4...20 mA. It has four switchable temperature ranges and is applied in nonaggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and clean room technology. These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for humidity measurement. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
