Bard 8406-157BX - High Pressure Transducer
The Bard 8406-157BX is an OEM high pressure transducer used on Bard wall mounted heat pump systems to convert refrigerant discharge pressure into a control board signal for monitoring, diagnostics, and system protection. This sensor is commonly applied on Bard WH Series variable speed wall mount heat pumps and is designed to provide a stable 0.5 to 4.5 V output across a 0 to 650 psi pressure range so the unit can manage capacity and respond to abnormal operating conditions. Because pressure transducers are application and control specific, confirm your model and wiring match before ordering, and replace the sensor any time the system shows erratic pressure readings, fault codes tied to high side pressure, or suspected sensor drift.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
