HYGRASGARD® RPFF-25-U

Item No. 1201-7121-0000-100
EAN 4 251325 611358

The calibratable pendulum room humidity and temperature sensor HYGRASGARD® RPFF - 25/ RPFTF - 25 with pluggable metal sinter filter, housing made of impact-resistant plastic, 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 is equipped with four switchable temperature ranges. The sensor is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and clean room technology, hotels, technical rooms, meeting rooms and convention centres. These measuring transducers are designed for exact detection of temperature and humidity. A digital long-term stable sensor is used as measuring element for humidity and temperature measurement. The sensor is appropriate for ceiling and duct installation, or for integrating it into equipment. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
