Introduction

The ACI outdoor air relative humidity transmitter features a thermoset polymer capacitive sensing element with a factory-installed hydrophobic filter, providing a proportional analog current or voltage output signal. The hydrophobic filter enhances resistance to moisture, dust, and other chemicals, improving long-term reliability. This outdoor air relative humidity transmitter incorporates DIP switches for field selection of the appropriate output signal and supply voltage to meet application requirements. Each unit also offers 0%, 50%, and 100% test options to verify proper transmitter operation and wiring. Field calibration is possible via increment and decrement calibration DIP switches without replacing the sensing element. These enhancements improve flexibility and long-term reliability. The outdoor air configuration features a weatherproof Euro-style enclosure with a sealed cover and a conformal-coated circuit board for enhanced protection against moisture and chemical corrosion. A three-point NIST calibration certificate is available.
