Honeywell Introduces the PX2 Series Heavy Duty Pressure Transducers

Logo.jpg

Configurable Pressure Measurement Devices (7 bar to 34 bar) Provide Reliable Performance in Moderately Harsh Media Environments

Honeywell expands its Heavy Duty Pressure product portfolio with the PX2 Series Heavy Duty Pressure Transducer. These new highly configurable, stainless steel pressure measurement solutions are engineered to be resistant to moderately harsh media such as refrigerants, brake and hydraulic fluids, engine oil, tap water, and compressed air.

The PX2 Series is designed to monitor performance and efficiency in a wide range of potential industrial applications including HVAC/R equipment, air compressors, system pressure, factory automation, pneumatics, valves, pumps, packaging/laminating equipment, sprayers, lasers, foam dispensing, solar energy, and emissions monitoring. Potential transportation (heavy equipment, alternative fuel vehicles) applications include system pressure, pneumatics, light hydraulics, brake and engine oil pressure, transmissions, and truck/trailer air braking.

“With the PX2 Series, our customers can truly have it their way,” said AJ Smith, director of global product marketing for Honeywell Sensing and Control. “We designed the PX2 Series to be highly configurable and durable, with a wide pressure range, so customers can select the form factor and functionality they want to help them reduce their design and implementation costs while still meeting challenging application requirements.”

The PX2 Series use piezoresistive sensing technology with ASIC (Application Specific Integrated Circuit) signal conditioning. Their compatibility with varied media, combined with up to IP69K protection and CE compliance, allow for reliable performance in tough environments.

Designed for configurability, the PX2 Series’ numerous standard or custom connectors, ports, pressure types and ranges, and output options allow customers the ability to configure devices to meet their specific application needs, and to obtain product samples quickly. By configuring the transducer to meet system requirements, the PX2 Series reduces the design and implementation costs of the end product. New standard configurations are regularly being added to the Series.

The PX2 Series is fully calibrated and compensated for transducer offset, sensitivity, temperature effects, and non-linearity using an on-board ASIC. The industry-leading Total Error Band of ±2% over the compensated temperature range of -40 ºC to 125 ºC [-40 °F to 257 °F] provides excellent interchangeability due to minimal part-to-part variation in accuracy, eliminates individual transducer testing and calibration, and supports customer system accuracy and warranty requirements.

These transducers measure absolute or sealed gage pressure. The absolute versions have an internal vacuum reference and an output value proportional to absolute pressure. The sealed gage versions have an internal pressure reference of one atmosphere at sea level. They are available in 7 bar to 34 bar [100 psi to 500 psi] pressure ranges with additional pressure ranges coming soon. Good EMC protection means that the transducer will not be damaged by environmental electromagnetic interference.

The PX2 Series is designed to Six Sigma standards, providing the highest level of product quality, performance, and consistency. Honeywell’s knowledgeable application engineers are available to answer customers’ specific design questions during the development, launch, and production of this product. Honeywell’s global presence offers customers immediate product and application support throughout the development cycle from design to global manufacturing.

Honeywell Introduces Upgraded ASDX Series Ultra-Low-Pressure Silicon Pressure Sensors

Logo.jpg

Devices Provide Enhanced Performance, Accuracy, and Sensitivity While Lowering Integration Costs

Honeywell has expanded its industry-leading ASDX Series silicon pressure sensor portfolio with ultra-low pressure ranges that include 0 to 10 inches of H2O gage, ± 10 inches of H2O differential, and ± 5 inches of H2O differential. These sensors include additional signal conditioning integrated within the product, allowing customers to remove components associated with signal conditioning from their PC board to free space and reduce costs normally associated with those components.

ASDXO

The Application Specific Integrated Circuit (ASIC)-based design provides a fast, highly accurate, amplified, conditioned pressure reading. Ratiometric 12-bit analog output for reading pressure over the specified full scale pressure span and temperature range allows for fast and easy integration into standard electronic circuits, and 12-bit I2C or SPI digital interface for reading pressure over the specified full scale pressure span and temperature
range minimizes connections and provides higher resolution and faster performance through reduced conversion requirements and the convenience of direct interface to the microprocessors and microcontrollers.

The ASDX Series achieve a tight total error band of ± 2.0% of full scale span maximum, providing enhanced sensitivity and accuracy even at ultra-low pressure ranges. Custom calibration ranges (inches H2O, psi, mbar, bar, kPa), supply voltage of 3.3 Vdc or 5.0 Vdc, and absolute, differential, and gage pressure types expand application opportunities.

These ultra-low pressure sensors are intended for use with non-corrosive, non-ionic working fluids, such as air and dry gases. The ASDX Series pressure sensors are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity. Calibrated output values for pressure are updated at approximately 1 kHz.

The ASDX Series silicon pressure sensors may potentially be used in industrial and medical applications including barometry, flow calibrators, gas-flow instrumentation, sleep apnea/therapy equipment, pneumatic controls, and ventilation/airflow monitors.

in Harsh Environments

Honeywell introduces the Series 1000 pressure switch for potential hydraulic brake pressure applications. Honeywell’s Series 1000 switch excels in brake systems used in many harsh environments such as extreme weather conditions or particle-filled areas due to its IP65 sealing and high burst rating. With its high resistance to shock and vibration, this pressure switch is designed to withstand pressure spikes in critical systems.

Series_1000.jpg

Honeywell Sensing and Control has utilized our engineering expertise to reduce part count on this product by approximately 75%. With fewer parts, the switch’s cost and complexity are optimized. The new design may contribute to lowering installation time by minimizing the time required for adjustments and potentially the need for field maintenance. The result is reduced field failures, even in the most demanding environments. Custom versions of this product have been in operation for over 2 years in 20,000 ATVs with no known field failures reported.

With its small size and superior sealing, the Series 1000 pressure switch may be used to actuate brake lights in brake systems for small vehicles used in many harsh environments.  Typical vehicles include ATVs, snow, and sport vehicles as well as smaller motorcycles and scooters. The switch may also be used in applications where high operating pressure and low set point are required. Other potential applications may include hydraulic brake systems in small vehicles, compact agriculture tractors, utility vehicles (UTVs), trucks, lift trucks, and other small self-propelled vehicles.
