On-wall humidity sensor / outdoor humidity sensor HYGRASGARD® AFTF-20 VA
Calibratable HYGRASGARD® AFTF - 20-VA outside humidity and temperature measuring transducer (± 1.8%) with metal sinter filter, rugged housing in V4A stainless steel, optionally with/without display, with cable gland or M12 connector according to DIN EN 61076-2-101.
The device measures the relative humidity and the temperature of the air and converts these measurands into a standard signal of 0-10 V or 4...20 mA. It supports four switchable temperature ranges and is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and cleanroom engineering. The sensor device provides precise detection of humidity. A digital long-term stable sensor is used as measuring element for humidity. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
