Setra’s capacitive pressure transducers are expertly designed adaptations of a simple, durable and fundamentally stable device...the electrical capacitor. In a typical Setra configuration, a compact housing contains two closely spaced, parallel, electrically isolated metallic surfaces, one of which is essentially a diaphragm capable of slight flexing under pressure.

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

Recently, the Department of Energy (DOE) released a new requirement that goes into effect on Jan. 1st, 2017 as part of the "Energy Conservation Program: Test Procedures for Central Conditioners & Heat Pumps.” All manufacturers of heating and cooling systems need to ensure that the AHR units they manufacture for residential and small commercial applications meet this new standard.

Total Error Band (TEB) is a measurement ofworst 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.

Have you ever wanted to build your own Haunted House or Spooky Trail?
I'm sure we've all thought about it one time or another. You know what I'm talking about. Places like amusement parks, fairs, or even a homemade one that your “Halloween Crazed” neighbors down the street built themselves. But how do they work?

Low pressure measurements are required in various applications such as air flow, static duct and cleanroom pressures inHVACand 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

湿度的准确测量在许多HVAC/R应用中是重要的。相对湿度(RH)是“实际湿度”的量度，相对于给定温度下的最大可能湿度。RH传感器包含一个由集成传感器和发射器组成的组件。传感器测量RH，而发射器产生与感知RH成比例的输出信号。There are two common types ofhumidity sensing elementsthat are most widely used; Capacitive and Resistive.

When selecting anindustrial pressure transducerfor monitoring high temperature liquids or gases be sure to check the operating temperature range of the transducer, in order to select the correct pressure transducer for these applications.

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.

Thank you to all who visited us at Booth 1244 in the Building Automation and Controls section of the AHR Expo this year in Orlando, Florida. We enjoyed seeing both new and familar faces! The world's largest HVACR event was anything but boring and we think the 60,000 attendees would have to agree.
