Calibratable duct humidity- ⁄ temperature sensor, with plastic sinter filter, housing made of impact-resistant plastic with quick-locking screws, with
cable gland. 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 non-aggressive 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.
