There is no guarantee of a perfect, contaminant free cleanroom. However by adhering to room pressure requirements, proper gowning procedures and by understanding the origins of the contaminants, users can minimize contamination risk to ensure safe testing and manufacturing environment. These are some of the things you may not have realized can compromise a cleanroom, and some possible ways to reduce the contamination of the source.

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.

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.

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.

A common issue that users see is that a new device is added to a network but is not communicating with the segment or has intermittent communication. Troubleshoot BACnet communication problems through the following steps:

Hospitals and outpatient facilities serve a critical need in global communities. They provide emergency care for the sick, but we also rely on them as a safe zone for treating communicable diseases and keeping the public safe. Pressurized rooms in these special buildings are designed to contain dangerous airborne contaminants, such as tuberculosis, aspergillus, and vaporized cough. When properly pressurized, these rooms protect the most vulnerable patients, and allow healthcare staff to safely treat highly infectious cond

Any design engineer must seriously consider the manufacturing environment when looking to select a pressure transducer for inclusion within a refrigeration chiller, pump, engine test equipment, or other machinery. The life of a pressure transducer is proportional to the system design and assembly process.
