P499 Series Electronic Pressure Transducers Product/Technical Bulletin 1

Refer to the QuickLIT Web site for the most up-to-date version of this document.

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 Benefits

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 and Refrigeration 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.

Slender Body Design Facilitates use of deep-socket wrenches for ease of installation;

requires zero turning radius.

1% Total Error Band Provides high-accuracy performance.

CE and UL Agency Listings Allow for global applications.

IMPORTANT: The P499 Series Electronic Pressure Transducers are intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the P499 Electronic Pressure Transducer could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system.

Installation To mount the P499 transducer: See Mounting and Wiring for information on installing the P499 Series Electronic Pressure Transducers. 1. Hand thread the P499 transducer to the pressure tap point. Parts Required 2. Tighten the connection using the wrench flats provided to avoid damaging the transducer. P499 transducers require wire harnesses for all models that do not have an integral cable. Use Table 2 to select a wire harness.
