Bard 8408-056BX EEV Thermistor Temperature Sensor

The Bard 8408-056BX is a 10K ohm NTC (Negative Temperature Coefficient) thermistor sensor designed specifically for Electronic Expansion Valve (EEV) control systems in Bard HVAC equipment. This precision temperature sensor is a critical component of the EEV system, monitoring suction line temperature to provide real-time data to the control board for accurate superheat calculation.

Key Features:

• 10K ohm NTC thermistor with ±10% tolerance
• Designed for use with Bard EEV control systems
• Monitors suction line temperature for precise refrigerant flow control
• Compatible with Bard wall mount and packaged HVAC units
• Works in conjunction with pressure transducers for optimal system performance

The thermistor works as part of the complete EEV system, which provides tighter control and better capacity management in varying operating conditions compared to standard thermostatic expansion valves. When the sensor detects temperature changes, the EEV control board adjusts valve position to maintain proper superheat levels, typically around 13 degrees. This ensures optimal refrigerant metering to the evaporator for maximum efficiency and system performance.
