Johnson Controls P499AAP-101 Electronic Pressure Transducer 4-20mA 0-100 PSI 1/8" NPT

The Johnson Controls P499AAP-101 is a compact, economical, rugged electronic pressure transducer designed for use in commercial refrigeration and air conditioning applications. This transducer produces an analog 4-20mA signal based on the sensed pressure, making it compatible with most modern control systems and building automation platforms.

Key Features:

• 1/8 inch SAE 27 NPT external thread connection (Style 49) with 0-100 PSIG pressure range
• 1% total error band provides high-accuracy performance
• Pressure port machined from solid 17-4PH stainless steel with no O-rings, organic materials, or welds exposed to pressure media for leak-proof operation
• Digitally-compensated for highly accurate performance over broad temperature ranges, resisting wide ambient temperature swings, high humidity, condensation, and icing
• Environmentally protected electronics withstand adverse conditions associated with typical HVAC/R applications, including freeze/thaw applications on suction lines
• Compatible with corrosive and non-corrosive pressure media including water, condensate, carbon dioxide, glycol, most refrigerants (including ammonia), and many other compatible fluids and gases

This individual pack comes with the transducer only; wire harness must be ordered separately. The P499 Series offers reliable, repeatable performance with long operating life, minimizing service and replacement costs in HVAC, refrigeration, and air conditioning system installations.
