A Roundup of Currently- Available Pressure SensorsJanuary 17, 2014
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.
Compact Pressure Sensor/Transducer Minds The Budget
The AST4100 stainless steel pressure sensor from American Sensor Technologies is described as both compact and low cost. The sensor is compatible with a wide range of liquids and gases over pressure ranges up to 10,000 PSI and is available with outputs of 10 mV/V, 1V to 5V, 1V to 6V, or 4 mA to 20 mA. Operating temperature range is from -40°C to +85°C. Additionally, AST4100 pressure sensors employ the company’s proprietary one-piece stainless steel sensing element with Krystal Bond technology.
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.
Differential Pressure Transmitter Provides Closed-Tank Level Measurement
Keller America’s Series PRD-33 X differential pressure transmitter handles applications requiring high accuracy with high overload resistance in differential pressure ranges as low as 350 mbar. Integrating a second pressure sensor, line, or common mode, pressure can be measured along with the differential pressure. Features include a differential pressure range from 350 mbar to 3 bar, an overload resistance of ± 35 bar, and an RS-485 interface.

Sealed Sensors Suit Industrial Apps
Designed for industrial applications, Kavlico’s PTE5000 family of modular sensors feature a hermetically sealed design, making them suitable for use in harsh environments. Measuring about 20-mm high depending on the connector type, the low-weight components employ the company’s Thin Film strain gauge technology. They are available in standard pressure ranges from 0 to 6 bar to 0 to 600 bar with higher ranges available on request. Operating temperature ranges from -30°C to +100°C.

Solid-State Pressure Sensors Address Cost-Sensitive Designs
Description The NPC-410 Series of solid state pressure sensors from GE Sensing provide a cost-effective solution for applications that require long-term stability and high volume. In a dual-in-line configuration, the sensors are intended for PCB mounting and offer optional pressure port and lead configurations to accommodate low-profile apps where connection orientation is critical. Based on NovaSensor’s advanced SenStable piezoresistive sensing technology, the NPC-410 series is available in pressure ranges from 0 psi to 5 psi (0 bar to 0.34 bar) through 0 psi to 100 psi (0 bar to 7 bar). Contact the GE for other pressure ranges.
Low Pressure Transmitters Sustain Performance Levels
For designs requiring consistent levels of performance, reliability, and stability, Gems’
3300 Series low-pressure transmitters units come in small packages with all stainless steel wetted parts at an attractive price-to-performance ratio. Features include pressure ranges from 0 to 600 psi (0 to 41 bar), an operating temperature up to +125°C (257°F), and a choice of outputs, electrical connections, and pressure ports. Long-term drift is 0.2% FS/YR (non-cumulative) and accuracy is 0.25% FS.
Pressure Sensor Interfaces Via USB
Eliminating the need for costly I/O interface boards, the GS4200-USB pressure sensor from Ellison Sensors measures pressure directly on a computer via a USB interface. Users can measure up to 16 pressure inputs simultaneously with 21-bit resolution. The component is available in high pressure ranges and is powered by the computer’s USB port. Data is displayed in graphical or tabular form on the PC via ESI-USB configurable Windows Interface software. Data can be saved to a file or exported to Excel.
Pressure Sensors Sport Stainless Steel Suits
For challenging apps in high temperatures and unfriendly environments, Balluff’s pressure sensors are configured quickly and easily in conformance with VDMA standards. The components meet IP 67 requirements and are suitable for use in wind turbine, offshore, and refrigeration and air-conditioning applications. Features include local pressure displays, binary switching outputs, analog output signals, pressure range up to 600 bar, and an operating, -40°C to +125°C.
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.
