The regulation language in U.S. Pharmacopeia Standard 797 (USP 797) has long been the guiding principle for cleanliness in hospital pharmacies that treat cancer patients with compounding sterile preparations (CSPs). For airflow in these special rooms, USP 797 outlines how spaces are to be pressurized, and what are permissible parts per million (PPM) particle counts.

What is a PID loop?
In HVAC systems, various motors and devices need to be controlled with modulated signals to turn damper actuators and hydronic reheat valves. Most controllers in the industry do this using specific and standard logic, called a Proportional Integral Derivative (PID) controller, or PID Loop. PID is mathematical logic that provides these three functions as parameters that can be tuned, so devices function accurately and optimally.
From August 14th through the 17th, Setra Systems will be exhibiting at the NCSL International Workshop & Symposium taking place at the Gaylord National Convention Center in National Harbor, MD.
The theme of this year’s symposium is “Precision & Performance with Measurement Science”:
From August 6th through 9th, Setra Systems will be exhibiting at the 54th ASHE Annual Conference & Technical Exhibition in Indianapolis, IN. Associates from Setra will join nearly 4,000 other professionals to discuss healthcare compliance, updates to codes and standards, and other emerging trends in healthcare facility management.

How do we know that hospitals are safe?
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 at-large safe. But how can we know for certain that a hospital is clean and safe, and that we won’t get sick from something another ill patient has carried in?

Setra Gives Back on its 50th Anniversary
This year, Setra Systems celebrates 50 years of designing and delivering premium sensing solutions. Brothers Y.T. Li and S.Y. Lee founded Setra in 1967 shortly after developing the variable capacitance transduction principle. Since then, Setra has grown to become an industry leader in the field of high-accuracy pressure sensing.
User-side energy submetering is becoming increasingly popular in new commercial construction and renovation projects alike. The latest advanced LEED certification requires operator-owned submeters to be installed in high consumption areas and facilitate continuous tracking of total consumption for an entire structure.
The BACnet community is proud to announce that Setra has become the latest company to join BACnet International as a Silver member. Setra, founded in 1967, designs and develops one of the most comprehensive portfolios of sensors in the world. It has nearly 50 years of experience in critical applications in many industries, and is part of the Fortive Corporation, a Fortune 500 science and technology leader.

How to Select a Power Meter
What Are You Monitoring?
One critical consideration when searching for a proper power meter is to determine what you're measuring. Is the monitored load signal-phase, split-phase or three-phase? What voltage/current ranges are going to be monitored?
If you're interested in a power meter for residential or light commercial applications, then typically a single or split-phase meter would be the best cho
