• Reduced current consumption: Helps to reduce energy
costs, and enhances product life if used in battery driven
systems.
• Media compatibility: Common HFC (hydrofluorocarbon)
refrigerants such as R410A and R134A, next generation low
global warming potential (GWP) refrigerants such as R448A
(Solstice® N40), R32 and R1234ZE, engine oil, petroleum-
based hydraulic fluids, DOT 3 brake fluid, and dry air. For
ammonia and other corrosive media, see Honeywell’s SPT Series.

DESCRIPTION
• Optional diagnostics mode: Beneficial in applications where
the sensor functionality and the need to know internal or
external failure modes is critical.
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 -40ꢁC to 125ꢁC ꢂ-40ꢁF to
257ꢁF].
• 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.
VALUE TO CUSTOMERS
• Total Error Band (TEB) 1.0 ꢀFSS from -20ꢁC to
85ꢁC: Provides the most comprehensive, clear and
meaningful indication of the sensor’s true measurement
performance over a specified temperature range; small
error promotes system uptime and efficiency. (See Figure 1.)
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 -20ꢁC to 85ꢁC ꢂ-4ꢁF to 185ꢁF]
• External freeze/thaw resistance: 6 cycles from -30ꢁC to
50ꢁC ꢂ-22ꢁF to 122ꢁF]

• High insulation resistance and dielectric strength: Protect
the user and sensor in high over-voltage situations,
and ensures that the device is compliant with industry
standards.
• High EMC performance: Operates reliably in the presence
of electro-magnetic fields, such as near wireless signals, RF
communication, and electrical devices.
• High external freeze/thaw resistance: Survives exposure to
frost, commonly found in refrigeration systems. (See Figure 2.)
The PX3 Series is not recommended for use with media
involving water, saturated air such as steam and vapor, and
ammonia.
