1 / 8 page  Figure 2. PX3 Series External Freeze/Thaw Resistance • 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. 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, non- ionized air) • Dielectric strength: AC1500V, 1 min. or AC1800V, 1 s (in dry, non- ionized 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 The PX3 Series is not recommended for use with media involving water, saturated air such as steam and vapor, and ammonia. PORTFOLIO Honeywell’s PX3 Series joins the PX2 Series, MLH Series, and SPT Series heavy duty pressure transducers. Sensing and Internet of Things 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]. VALUE TO CUSTOMERS • Total Error Band (TEB) ±1.0 %FSS from -20°C to 85°C: 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.) Figure 1. TEB Definition and Temperature Performance • 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.
