8406-128 OBSOLETE
- Pressure Transducer 0-700 PSI 5VDC
The Bard 8406-128 pressure transducer is an OEM HVAC sensing component used to monitor system pressure and convert it into a low-voltage signal the unit controls can read for proper operation and protection. This style of transducer is commonly applied in Bard commercial wall-mounted air conditioners and heat pumps where accurate pressure feedback helps the control circuit manage performance and fault conditions. If you are troubleshooting pressure-related lockouts or control issues, replacing a drifting or failed sensor with the correct Bard 8406-128 helps restore reliable readings and proper equipment response. Always confirm your model and required pressure range and connector style before ordering to ensure an exact fit.
