Platinum RTD Technology
Platinum RTD sensors are widely preferred in commercial HVAC and building automation for their superior accuracy, repeatability, and resistance to drift over time. The 1,000 Ohm configuration provides excellent resolution and is less susceptible to lead wire resistance errors compared to lower-resistance RTD types, ensuring dependable readings across a wide temperature range.
Applications
- Outdoor air temperature monitoring for BAS and DDC systems
- Economizer and free-cooling control
- Outdoor air reset for hydronic heating and cooling systems
- Energy management and demand control strategies
- Commercial and light industrial HVAC installations
