Used almost interchangeably across the sensor industry today, the terms transducer and transmitter actually have fundamentally different meanings.  Before going into those differences, a transducer and a transmitter are both sensors; in this case both sensing pressure.  A pressure sensor converts an applied pressure of a gas or liquid into a usable output.  The type of output the sensor gives, defines whether a unit is considered a transducer or transmitter.

Explosions are always possible in hazardous environments. Practical solutions for explosion protection are vital prerequisites for electrical instrumentation and safety measures must ensure a degree of freedom for the connections in the safe area. Ensuring that all electrical loops are initially designed to meet all safety and installation criteria is critical. The output of equipment should be installed and tested so that no additional explosion proof measurements need to be taken later. The most practical way to provide this level of both protection and freedom is by intrinsically safe equipment.

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.
