Capacitive Transducers

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. 

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

Recently, the Department of Energy (DOE) released a new requirement that goes into effect on Jan. 1^st, 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 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. 

Happy Halloween From Setra

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 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

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.

When selecting an industrial pressure transducer for 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.
