The ACI Relative Humidity Nickel RTD Room Series utilizes a thermoset polymer capacitive sensing element with a factory-installed hydrophobic filter to enhance moisture protection. The multi-layer construction of the sensing element also provides excellent resistance in applications where dust, dirt, grease, and common environmental chemicals are present. The relative humidity room sensor includes an onboard DIP switch that allows users to select the desired output signal and can be powered by either AC or DC power supplies. Single-point field calibration can be performed using the increment and decrement calibration DIP switches, adjusting the curve up or down in ±0.5% increments with each toggle of the corresponding switch. These improvements provide greater flexibility and outstanding long-term reliability, eliminating the need for field sensor replacement. The series offers two enclosure options designed to meet most commercial décor requirements. Both enclosures feature four-way airflow to minimize self-heating. A three-point NIST calibration certificate is available.
