Precision RTD Temperature Monitoring for Ducted HVAC Systems
The A/TT100-D Series is a high-accuracy duct temperature transmitter designed for air handling units, rooftop HVAC systems, and mixed or return air duct monitoring. Each unit uses a platinum 100Ω RTD (PT100) sensor and delivers a reliable 4–20 mA loop-powered output, ensuring compatibility with BMS/BAS platforms.
Factory-calibrated to DIN EN 60751 Class A accuracy and equipped with a rugged 12" (30.48cm) 304 stainless steel probe, these transmitters offer excellent stability and fast response. Choose from four enclosure options (NEMA 1, 3R, 4X, or plenum-rated) to match your site’s environmental conditions.
