Does Your Product Fall Under New RoHS2 Restrictions?

Newly Added Restricted Products Under RoHS2 Affects Manufacturing

In 2013, RoHS2 was created by the European Union legislation, nearly a decade after the original RoHS (Restriction of Hazardous Substances Directive) was implemented.  RoHS2 is merely an evolution of RoHS1 that provides greater clarity on the legal scope of products that should adhere to the hazardous material guidelines. The combination of

What is Total Error Band & How do You Calculate It?

Total Error Band (TEB) is a measurement of worst case error; it is the most comprehensive and concise measurement of a sensors true accuracy over a compensated temperature range.  TEB is extremely important to know when trying to determine how well a sensor will work within a particular design system. By calculating TEB you'll be able to understand the different possibilities for error. Formulating TEB can be tricky if you don't have the right inputs readily available.

4 Considerations For Low Pressure Measurements

Low pressure measurements are required in various applications such as air flow, static duct and cleanroom pressures in HVAC and energy management systems (EMS).  Other applications include use in medical instrumentation, environmental pollution control, boil combustion efficiency and a wide variety of research and development requirements.  Although the focus will center mainly on air flow and pressure, the same principles

How Is Humidity Measured?

The accurate measurement of humidity is important in many HVAC/R applications. Relative Humidity (RH) is a measure of the ‘actual humidity’, relative to the maximum possible humidity at a given temperature. RH sensors contain an assembly that is made up of an integrated sensor and transmitter. The sensor measures the RH while the transmitter creates an output signal proportional to the sensed RH. There are two common types of humidity sensing elements that are most widely used; Capacitive and Resistive.

HVAC Trends 2016

2016 is all about thinking smarter, with the integration of devices and innovation working together to improve a process rather than focusing on a single technology or behavior. Businesses are thinking smarter by developing extensive resource management strategies to drive cost savings. From intelligent buildings to waste management, this year’s energy management trends can give companies a real competitive advantage, especially in a time of changing energy grids, rising water prices, and tighter regulation.
