ACI relative humidity indoor series with thermistor utilizes a thermoset polymer capacitive sensing element, factory-equipped with a hydrophobic filter to enhance moisture resistance. The multilayer construction of the sensing element provides excellent resistance in applications where dust, dirt, grease, and common environmental chemicals are present. The relative humidity indoor sensor features an onboard DIP switch that allows users to select the desired output signal, and can be powered by either AC or DC supply. Single-point field calibration is achieved using increment and decrement calibration DIP switches, with each actuation adjusting the curve up or down in ±0.5% increments. These improvements enhance flexibility and long-term reliability, eliminating the need for field sensor replacement. The series is available in two enclosure options designed to meet most commercial décor requirements. Both enclosures feature a four-way airflow design to minimize self-heating. A three-point NIST calibration certificate is available.
