BAPI Room Duct, and OSA Humidity Transmitters
Model BA/H Series 2% and 3% Accuracy humidity transmitters are designed specifically for HVAC systems. The room transmitters use Delta or BAPI-Stat II enclosures with optional communication jacks. All duct and OSA units come in weatherproof enclosures selectable for NEMA 3R or IP66 applications. All BA/H transmitters have optional temperature sensors or temperature transmitters. Transmitter outputs include 4-20mA, 0-5V ad 0-10V with replaceable sensors.
