Honeywell’s Heavy Duty Pressure Transducers PX3 Series
Honeywell’s PX3 Series Pressure Transducers use piezoresistive sensing technology with ASIC (Application Specific Integrated Circuit) signal conditioning in a brass housing and Metri-Pack 150 electrical connector. 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 typ.): 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.
- 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.
- Low current consumption: Helps to reduce energy costs, and enhances product life if used in battery driven systems.
- Media compatibility: Common HFC (hydrofluorocarbon) refrigerants, next generation low global warming potential (GWP) refrigerants such as R32 and R1234ZE, petroleum oils, lubricants, hydraulic fluids, brake fluids, air and water. For ammonia and other corrosive media, see Honeywell’s MLH Series and SPT Series.
Differentiation
- Efficient: Proven, tight TEB accuracy.
- Great customer value: Multiple configuration possibilities with the right combination of features provide flexibility of use in the application; configurability on standard ports, pressure reference type, media seal type, and pressure range with no upfront NRE or tooling charges.
