Bard 8602-064BX Solid State Enthalpy Sensor for HVAC Economizer Systems

The Bard 8602-064BX is a solid-state enthalpy sensor designed for precise measurement and control in commercial HVAC economizer applications. This sensor measures both temperature and humidity levels to determine the total heat content (enthalpy) of air, enabling HVAC systems to make intelligent decisions about when to use outdoor air for free cooling versus mechanical cooling.

Key Features:

• Solid-state construction for reliable, long-term performance
• Measures both temperature and humidity for accurate enthalpy calculation
• Designed specifically for Bard HVAC rooftop units and air handlers
• Enables energy-efficient economizer operation by comparing outdoor and return air conditions
• More accurate than basic dry bulb temperature sensors in humid climates
• Helps reduce compressor run time and lower utility costs

Enthalpy sensors are essential components in modern HVAC economizer systems, which automatically bring in outdoor air for cooling when conditions are favorable. By measuring total heat content rather than just temperature, this sensor ensures optimal system performance and prevents introducing humid outdoor air that could compromise comfort. The solid-state design offers improved accuracy and reliability compared to older electromechanical sensors, making it ideal for commercial buildings, retail spaces, and other applications where energy efficiency and proper ventilation are priorities.
