Here is a roundup of just a few of the latest and greatest pressure sensors
on the market, part one
Pressure Transducer Targets Industrial Applications
The Model XPA-1U pressure transducer from tecsis LP debuts as a highly accurate device, suitable for use in rugged industrial settings. It delivers 0.05% FSO (BFSL) accuracy with reliable repeatability. The XPA-1U requires 10-Vdc excitation and provides a standard 2-mV/V output with internal or in-line amplification optionally available. Pressure measurement ranges from 0 to 15 psi to 0 to 10,000 psi with gage or absolute reference. Other features include a burst pressure of 300% of the rated pressure, 17-4PH stainless steel wetted parts, and an operating temperature from -65° to +250°F, compensated from +60° to +160°F. Price starts at $885.

Heavy Duty Pressure Transducers Are Highly Configurable
Described as highly configurable components, Honeywell’s PX2 Series heavy-duty pressure transducers pair piezoresistive sensing technology with application specific integrated circuit (ASIC) signal conditioning. In stainless steel housings compatible with harsh media (brake fluid, refrigerants, engine oil, tap water, hydraulic fluids, and compressed air), the series is fully calibrated and compensated for transducer offset, sensitivity, temperature effects, and non-linearity via an on-board ASIC. Specs include pressure ranges from 7 bar to 46 bar (100 psi to 667 psi) and an operating temperature range from -40 ºC to +125 ºC.

Unique Pressure Sensor Technology Enables Compact designs
STMicroelectronics’ patented pressure-sensor technology isolates the pressure-sensing element within a fully molded package to meet the ultra-small form factor requirements for next generation of portable consumer devices. Integrating the isolated pressure-sensing element in a molded package allows for encapsulated wire bonding with zero risk of corrosion, elimination of wire bonding damage during pick and place assembly, zero risk of cap detachment or cap damage while the device is being mounted, and no impact on the sensor from the soldering process. Features include accuracy in the realm of ±0.2 mbar, zero drift, a noise figure of 0.010 mbar RMS, and a simplified calibration system.

Digital Pressure Sensor Manages Stress Well
All Sensors’ DLVR Series mini digital output pressure sensor employs the company’s CoBeam2 technology that reduces package stress susceptibility. The technology also promises to improve position sensitivity compared to single die devices. Supply voltage options ease integration of the sensors into a wide range of process control and measurement systems, allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter very low-power modes between readings to minimize load to power supply. Specs include 1 to 60” H2O pressure ranges, an operating temperature range from -25°C to +85°C, and a better than 1% accuracy over temperature. An optional protective parylene coating is available for moisture/harsh media protection.
