Using temperature stand-offs can replace expensive high temperature pressure sensors.

When selecting a pressure transducer for monitoring high temperature liquids or gases, be sure to note the operating temperature range of the transducer. This specification is included under environmental data on most manufacturers’ data sheets. The temperature compensated range specification of a transducer is the error introduced as temperature increases or decreases from 70°F. This thermal error affects both the span and zero setting of the transducers analog output and is generally listed as a percent of full scale per degree (% FS/°F). The static accuracy (accuracy at 70°F) of the pressure transducer plus the thermal error introduced by a high temperature pressure source is the total possible error for a specific high temperature pressure measurement

The MicroCal™ automated pressure calibrator is used as a stand-alone calibration standard for differential and gauge pressure sensors found in critical environments. Setra partnered with NASA to develop the industry’s quickest and most stable pressure control for low range applications. The Micro-Cal™ combines precise pressure control with high accuracy modular pressure references providing the quickest and most accurate calibration solution available on the market today.  The MicroCal™ is an easy-to-use solution that significantly improves labor productivity and efficiency when compared to the leading competitors, providing immediate ROI.

Apprenticeship Programs: The Solution For More Skilled Workers

A shortage in skilled labor is a serious issue in United States'

manufacturing industry.  Why? There's a misconception of what kind of training someone needs to have in order to enter professions within this industry.  Many begin to build their skills through trade school before becoming a manufacturing professional.  These students don't always get the proper hands-on training that can truly prepare them for the complex world of manufacturing  Yet with these schools, there's still the perception that traditional degrees have more long-term value than vocation training.

Thin Film Technology Strain Gauge

Thin film pressure transducers are made by vapor deposition or sputtering of insulation and strain gauge elements directly on a polished pressure sensing diaphragm or beam. The desired strain gauge pattern is deposited either by masking the non-conductive areas or by etching away unwanted conductive material. Laser trimming is used to calibrate the resistive elements.

Many of the following technical specifications appear on datasheets for pressure transducers and similar devices. Here we review their technical definitions and relationships.

Root Sum Squares (RSS): accuracy of a pressure transducer is calculated by taking the square root of non-linearity + hysteresis + non-repeatability.

Industrial pressure transducers are used in a wide variety of applications ranging from HVAC/R compressors, refrigeration and variable speed pumps to hydraulic pressure, oil and water. A transducer can be used anywhere there's a pipeline or chamber, its function is to sense and convert pressures into a proportional electrical output signal that is transmitted to monitoring or control system.

With different equipment comes different air pressure testing techniques for measurement. But are you sure if your procedures up to date? This article breaks down specifically what methods need to be implemented for different scenarios. These new steps in calculating

Take action and become a company that practices Lean Six Sigma by:

• Having repetition/replication throughout different supply chains
• Being cross-functional
• Using technology where ever possible
• Encouraging positive reinforcement

One obstacle that's in the way of adopting this lean system is a lack of trust.
