Master the Basics With HVAC Terminology

Absolute Pressure — Pressure measured relative to full vacuum. Referred to as pounds per square inch absolute (PSIA).

Atmospheric Pressure — Pressure of the atmosphere at the earth’s surface NIST standard atmospheric pressure = 1.01325 bar.

BAR — Unit of pressure (or stress). 1 bar = 750.07 mm of mercury at 0°C, at 45°.

Look no further than the recent Ebola case in the US to understand that one of the greatest fears in the general population is the rapid spread of infectious disease. When infectious diseases such as Ebola and MERS make an appearance, they immediately become front page news and are featured by every media outlet across America. 

While there are many strategies employed to prevent these infectious diseases from becoming a

Setra is proud to announce the launch of our new website!

For the past five months, Setra’s marketing team has been working hard to develop a new and improved website that offers a user friendly experience and responsive design. Additionally, we went one step further and have rebranded Setra with a more modern and impactful logo.

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.

 Pressure Transducers in Test & Measurement:

Particle Test & Analysis

Pressure transducers are commonly used in particle test and analysis applications. Learn how sensors are used within three different scenarios of particle test and analysis.

Porosimeters/Permeameters

These products are utilized for grain volume measurements, direct pore volume measurements, and grain density determination. 

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.

3 Ways To Have Room In Your Budget For An Energy Management System

With smart meter demand rising, price points still don't seem to be budging from its premium peak. Many don't realize that with an energy management program in place, the return outweigh the costs. Finding a budget is the first obstacle that needs to be tackled when looking into this expensive solution.

Alternating Current - current that reverses its direction of flow periodically (Hz).

Ampere - a unit of measure for the rate of current flow

Apparent Power - applied voltage multiplied by current in an AC circuit. This value would not take the power factor into account. Unit is volt amperes. (VA).
