DESCRIPTION

Honeywell’s PX3 Series Heavy Duty Pressure Transducers

use piezoresistive sensing technology with ASIC (Application

Specific Integrated Circuit) signal conditioning in a brass

housing and Metri-Pack 150 or cable harness electrical

connections. The PX3 Series are fully calibrated and

temperature compensated from -40°C to 125°C [-40°F to

257°F].

DIFFERENTIATION

• Optional diagnostics mode: Beneficial in applications where

the sensor functionality and the need to know internal or

external failure modes is critical.

• Great customer value: Multiple configuration possibilities

provide flexibility of use in the application with no upfront

NRE or tooling charges.

• Durable: Provides the tough environmental specifications

needed, including insulation resistance and dielectric

strength, external freeze-thaw resistance (see Figure 2),

and EMC performance.

FEATURES

• Pressure range: 1 bar to 50 bar | 15 psi to 700 psi (absolute

and sealed gage)

• Ratiometric output: 0.5 Vdc to 4.5 Vdc or 0.33 Vdc to 2.97 Vdc

• Fully calibrated and temperature compensated

• Total Error Band: ±1.0 %FSS from -20°C to 85°C [-4°F to 185°F]

• External freeze/thaw resistance: 6 cycles from -30°C to

50°C [-22°F to 122°F]

• Insulation resistance: >100 MOhm, 1500 Vdc (in dry, nonionized

air)

• Dielectric strength: AC1500V, 1 min. or AC1800V, 1 s (in dry, nonionized

air)

• Current consumption: 3.5 mA max.

• EMC (radiated immunity): 200 V/m per ISO 11452-2

• Ingress protection IP67 (Metri-Pack 150), IP69K (cable

harness)

• Response time: <2 ms

• RoHS, REACH, and CE compliant

• Six industry-standard pressure port types, including a

tube port which provides for hermetically-sealed process

connection

POTENTIAL APPLICATIONS

• Industrial: Refrigerant pressure monitoring in HVAC/R

systems; air compressor system pressure

• Transportation: Air system monitoring; hydraulic oil pressure

monitoring
