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 Sensors in Gauge, Absolute and Sealed Gauge Ranges

System designers are usually aware of the specific differences between these types of pressure measurements. The pressure of interest is being measured relative to ambient barometric, full vacuum, or a sealed reference chamber, respectively.

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

Setra's NEW Industrial Catalog

The new 2014 Industrial Product Catalog is a comprehensive guide that contains the technical data sheets for products commonly used in Industrial applications.

• Section 1.1: General Purpose OEM
• Section 2.1: Test & Measurement
• Section 3.1: Sanitary Pressure
• Section 4.1: Accelerometer
• Section 5.1: Barometric Pressure
• Section 6.1: Very Low Differential Pressure
• Section 7.1: Power Monitoring

The sensing and measurement of physical quantities through small changes in electrical capacitance is scarcely a new concept. The natural benefits of this approach were recognized for many years. But it was not until Setra engineers introduced new materials, new designs, and innovative, dedicated circuitry that the techniques full potential was realized in the practical, real world of pressure measurement.

Here at Setra we realize that each customer is unique and every application has different requirements that necessitate different features in a pressure sensor. We have the best interests of the customer in mind and realize we may not have the best sensor for a particular situation.
