Pressure sensors for oil and gas industry

Honeywell added two models to their Wing Union/Hammer Union pressure sensor portfolio, which are designed for precision accuracy during drilling operations.


Honeywell added Models 425 and 427 to their Wing Union/Hammer Union pressure sensor portfolio, which are designed for precision accuracy during drilling operations (pictured: Model 425). Courtesy: HoneywellHoneywell Sensing and Control added the Model 425 and Model 427 to their Wing Union/Hammer Union pressure sensor portfolio.

The Model 425 is available in two accuracy levels (±0.2 % BFSL [Best Fit Straight Line] – Standard) or (±0.1 % BFSL – High Accuracy). The Model 427 (±0.2 % BFSL) provides a wide and shallow sensing port that facilitates the seamless flow of more viscous media blends. 

Both models provide accurate and reliable data for more confident detection of small changes in pressure, allowing the operator to quickly adjust media flow pressure during drilling operations. This helps drilling operators optimize oil withdrawal rates and profile potentially dangerous conditions such as gas bubbles to increase drilling personnel safety. 

Other features include:

  • Quick Installation/Serviceability – Designed for quick field installation, offers resistance to torque stress at hammer up with field adjustable zero and span for reliable long term performance.
  • Reliability/Durability – All welded stainless steel construction, with Inconel wetted parts for resistance to abrasive or corrosive media. Shock and vibration tested; CE, CSA / ATEX - Intrinsically Safe approvals.
  • Longevity – Hit it and forget it: Honeywell’s class leading reliability plus an annual calibration cycle allows customers to install and move on. 
  • Quick Availability – Multiple configurations available for quick shipment in less than 5 days, others available within 2 weeks. 

 More features:

  • Model 425 available with ± 0.1% high accuracy; or ±0.2% standard accuracy 
  • Model 427 with ±0.2% accuracy features a wider aperture design for use with more viscous media 
  • Both feature all-welded one-piece, hermetically sealed, stainless-steel construction and Inconel X-750 wetted parts for additional durability with abrasive or corrosive media 
  • Multiple electrical connections available 
  • RFI/EMI protected
  • Intrinsically safe option
  • CE approved; CSA/ATEX certification

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
