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
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 transducers operate with all pressure media
compatible with 17-4PH stainless steel, including most
non-corrosive refrigerants. They are also suitable for
use with ammonia.
The P499 Series provides transducers in numerous
pressure ranges, covering most common refrigeration
and air conditioning applications. These transducers
may also be used in other non-corrosive fluid
