Room pendulum humidity and temperature sensor HYGRASGARD® RPFF - 25/ RPFTF - 25

Calibratable HYGRASGARD® RPFF - 25 / RPFTF - 25 pendulum room humidity and temperature measuring transducer with pluggable metal sinter filter, housing made of impact resistant plastic, with/without optional display. The sensor device 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 with four switchable temperature ranges.

The transmitter is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and cleanroom engineering, hotels, technical rooms, meeting rooms and convention centres. It provides precise detection of temperature and humidity. A digital long-term stable sensor is used as measuring element for humidity and temperature. The sensor is suitable for ceiling and duct installation, or for integration into equipment. It is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
