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).

Popular Types of Current Sensors

Current Shunts

Current Shunts are low value resistors that are inserted into a circuit. The shunt provides terminals to connects the sensed current and voltage monitoring terminals. The commercially available shunts have sensed current ranges from less than 1A to several hundred amps.

Pounds per square inch (PSI) is a common unit of pressure used in many different pressure measuring applications. It’s typically used for non-SI industrial and technical purposes such as tire pressure, fuel storage & distribution, waste water management, and test & measurement activities, among many others.

Humidity sensing is important, especially during the cold winter months that many of us are currently experiencing. Properly installing and using humidity transmitters helps building automation systems understand when the air becomes too dry or too humid for comfort.

ACREX India 2015 to Be Hosted in Bangalore February 26-28

Last year ACREX India saw 30,000 visitors and 400 exhibitors from 25 countries gather in Pargati Maidan, New Delhi for the largest show on Air Conditioning, Ventilation, Refrigeration and Building Services. Not only did the trade show feature innovative new products from exhibitors, but eWorkshops and interactive panel discussions were available for all attendees.
