P499 Electronic Pressure Transducers; Style 47 Fitting
Shown on the Left and Style 49 Fitting Shown on the Right
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.
Refer to the P449 Series Electronic Pressure Transducer
Product/Technical Bulletin (LIT-12011190) for important product
application information.
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.
