Servoflo vs Honeywell: Board Level Pressure Sensors

Posted by Seta Davidian on Dec 30, 2019 9:12:42 AM

Users of pressure sensors enjoy a broad selection of models and manufacturers from which to choose. While detailed specifications of individual models are easy to come by, it often helps to see a comparison between specific brands to aid the selection process. The following blog post compares board-level pressure sensors from Servoflo and Honeywell.

Advantages of Servoflo Over Honeywell

At Servoflo, we distribute a broad range of pressure sensors from leading manufacturers, including Fujikura and Silicon Microstructures. Between the two, our sensor products meet the board-level pressure measurement requirements across different price and performance points for pressure ranges from 2-inch water columns (WC) to 150 psi (and even higher) for applications in the medical, HVAC, and industrial industries.

By partnering with us over Honeywell, our customers benefit from our:

Individualized Customer Service

We focus on providing individual attention to meet the unique needs of our customers rather than locking them into a single family of standard products that feature unnecessary features at additional costs. Additionally, Fujikura provides customers with the opportunity to produce modified sensor designs that fit their specific applications in very low volumes with little to no price premium or expensive upfront investment. This level of customer service and customizing is not available with Honeywell. 

Greater Flexibility and Added Benefits

In many cases, pressure is not the only parameter requiring measurement. Other critical parameters that may require monitoring include mass flow, humidity, and temperature. We consider all of these factors and more when curating our product selection to offer solutions that meet a broader range of applications at competitive prices. In addition, Honeywell does not provide benefits like inventory management, stocking, responsiveness, and easy access to technical support like we do.

Sample Overview of Fujikura Sensors

al4-headerFujikura’s AL4 pressure sensor is a low-pressure sensor with digital output. It consists of a silicon piezoresistive pressure sensing chip combined with a signal conditioning integrated circuit. This sensor amplifies the low-level signal from the sensing chip, applies temperature compensation and calibration, and converts it to digital data in proportion to the applied pressure. Highlighted features of this sensor include: 

  • Gauge: positive, negative, or bi-directional
  • Differential: new feature now available!
  • Pressure Ranges: 0–1 kPa (.145 psi) to 0–10 kPa (1.45 psi), depending on model
  • Pressure Media: non-corrosive gases
  • Supply Voltage (constant voltage): 5 +/-0.25 VDC, 3.3 VDC, or 3.0 VDC
  • Accuracy: +/-1.5% FS
  • Ports: dual barbed
  • Size: 11.36 mm x 10.32 mm x 10.32 mm SMT package

Typical uses include battery-operated devices, medical equipment, industrial pneumatic devices, and various consumer devices.

Overview of Silicon Microstructures Sensors

sm933x-headerMEMS pressure transducer technology and CMOS mixed-signal processing come together in the SM9333/SM9336 ultra-low differential pressure sensor. These sensors offer digital, fully conditioned, and multi-order pressure and temperature-compensated sensing. The highlighted features of this model include: 

  • Pressure Range: 125 Pa to 250 Pa differential
  • Digital Interface: 16 bit I2C
  • Compensated Temperature Range: -20° C to 85° C
  • Total Accuracy: +1% full-scale
  • Insensitivity to mounting orientation
  • Robust JEDEC SOIC (16 package with a dual vertical porting option)

Quality Sensors From Servoflo

The above highlighted products are 2 examples of our extensive product offering. We have many more product options that fit a wide variety of needs. High-quality products, individualized customer service, product design flexibility, and a variety of added benefits make Servoflo the better choice for board-level pressure sensor needs over Honeywell.
