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.

The Digital Altimeter Setting Indicator (DASI) System is a critical part of flight control and instrumentation. It assists with calculating the true altitude of an air plane relative to the ground.  Pilots use this altitude calculation for landing aircrafts safely on the runway. Without this system, pilots wouldn't have accurate altitude measurements accessible to them prior to landing.

Altimeters, a vital component within an aircraft, calculate and display altitude by measuring the barometric pressure and converting that measurement into altitude. The greater the altitude of the aircraft, the lower the altimeter pressure reading. Altimeters produce readings with respect to sea level. This is an inaccurate reading as a result of weather patterns and varying elevations of airport locations. Changes in weather can alter the readings at an airport control tower. As weather patterns move, high and low

Current switches and current transducers are often used in very similar applications. Common applications include: monitoring motor activity, detecting belt slippage or breaking in fan, monitoring for bearing wear in motors and detecting heating element failure or end of life.

It's almost here! The 2016 AHR Expo kicks off in three weeks on Monday January 25 in sunny Orlando Florida with a record breaking number of attendees and exhibitors. With hundreds of new products launching at the expo, there isn't a lack of HVAC innovation. Setra, this year located at Booth 1244 in the Building Automation section, is featuring multiple new products including the Power Patrol.

With over 2,000 organizations as featured exhibitors this year, there will be thousands of brand new products being highlighted across over a dozen applications. With only three weeks away from the 2016 AHR Expo, Setra is excited to be sharing its newest lineup of products to attendees.  Some of Setra's newest products are:

Hospital staffs face a barrage of beeping devices daily while caring for patients. Alarm fatigue, as it’s known, can cause staff to ignore alarms, especially if different devices have similar sounds or frequencies. Nuisance alarms are those sounds that do not represent a danger to the patient, but come from devices that cannot otherwise be configured to stop the alarm from sounding when a situation is neither important nor urgent.

The baud rate is the rate at which information is transferred in a communication channel. Baud rate is commonly used when discussing electronics that use serial communication. In the serial port context, "9600 baud" means that the serial port is capable of transferring a maximum of 9600 bits per second.

Pressure Sensor Installation: In the Wall or In the Ceiling?

The landscape of room pressure monitors is diverse, with many different options of product design from various manufacturers. One of the basic choices in product design is whether to include the differential pressure transducer on-board with the touch screen, or external in the ceiling or interstitial space. There are pros and cons for each approach, depending mostly on the preference of the A&E firm or customer.

Engine and Power Train Testing Applications

Pressure is a big part of engine testing and automotive component manufacturing. That’s why wherever you find engines being tested; you’ll likely find transducers measuring everything from air intake pressures to exhaust back-pressures. In the automotive industry, you’ll find transducers measuring everything from tire inflation pressure for dynamometer testing to controlling tool pressure during crankshaft journal burnishing. 

A frequent question asked about room pressure monitoring applications is “how much sensor accuracy do I need?” The most common thought is to order the most accurate sensor available. For a moment, consider all things are equal with regard to price. Is the best accuracy the best choice? Not always. It depends on the application.
