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
