Pressure Transducer, Class 1, Non-Intrusive Calibration, 0-100 PSI, for Commercial Refrigeration and Air Conditioning. (OBSOLETE)

ELECTRONIC PRESS TRNSDCR; 0-100 PSIS 1/4IN SAE 45 DEG FLARE INTNL THREAD (7/16-20 UNF)W/DEPRESSOR

Description

The P499 Series Electronic Pressure Transducers are compact, economical, rugged, direct-mount pressure transducers designed for use in commercial refrigeration and air conditioning applications. These transducers produce an analog signal based on the sensed pressure.

The P499 Series transducers feature environmentally protected electronics with stainless steel construction. The digitally compensated P499 transducers are highly accurate over a broad temperature range, resisting the effects of wide ambient temperature swings, high humidity, condensation, and icing.

The pressure port is machined from a solid piece of 17-4PH stainless steel. No O-rings, organic materials, or welds are exposed to the pressure media, allowing for a leak-proof, all-metal, sealed pressure system.

The P499 Series transducers operate with any corrosive or non-corrosive pressure medium that is compatible with 17-4PH stainless steel, including water, condensate, carbon dioxide, glycol, most refrigerants (including ammonia), and many other compatible fluids and gases. The P499 Series provides transducers in a variety of pressure ranges, covering most common refrigeration and air conditioning applications.

Features

• single-piece machined 17-4PH stainless steel pressure port provides a durable assembly that eliminates refrigerant loss due to O-ring or weld failures; resists damage due to physical shock, vibration, and pressure pulsations; enables use with non-corrosive or corrosive pressure media that is compatible with 17-4PH stainless steel.
• environmentally protected electronics withstand the effects of adverse conditions associated with typical HVAC/R applications, including freeze/thaw applications on suction lines.
• reliable, repeatable performance and long operating life minimizes service and replacement costs.
• many available pressure ranges provide a single line of transducers for all refrigeration and air conditioning application needs.
• 1% total error band provides high-accuracy performance.
• slender body design facilitates use of deep-socket wrenches for ease of installation; requires zero turning radius.
• CE and UL agency listings allow for global applications
  
  

Repair Information

If the P499 Series Electronic Pressure Transducer fails to operate within its specifications, replace the unit. For a replacement transducer, contact the nearest Johnson Controls® representative.

Accessories

P499 transducers require wire harnesses for all models that do not have an integral cable.

Refer to the P449 Series Electronic Pressure Transducer Product/Technical Bulletin (LIT-12011190) for important product application information.
