Room pendulum humidity and temperature sensor HYGRASGARD® RPFF / RPFTF

The calibratable HYGRASGARD® RPFF / RPFTF pendulum room humidity and temperature transmitter with plastic sinter filter measures relative humidity and air temperature of air. It converts the measurands into standard signals of 0-10 V or 4...20 mA, supports four switchable temperature measuring ranges and is available with or without optional display.

The measuring transducer is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and cleanroom engineering, in hotels, utility rooms, meeting rooms and convention centres. It 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 suitable for ceiling and duct installation, or for integration into equipment. The device is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
