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.

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 14^th through the 17^th, 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 6^th through 9^th, Setra Systems will be exhibiting at the 54^th 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.

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?

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.

Vivarium Defined

Vivariums are enclosed areas designed to provide a stable environment for animals and plants for observation or scientific research. Often, vivariums contain a portion of an ecosystem for a particular species with controlled environmental conditions on a smaller scale. A vivarium you would find in an academic research setting contains multiple racks of various sizes depending on the species it contains.

The Internet of Things (IoT) is changing the way people run their homes. More and more devices are becoming available to consumers that allow them to automate their thermostats and regulate their power consumption, often-times controlling these systems from the phone in their pocket. Products like the Nest thermostat and the Sense home energy monitor provide homeowners convenient tools that also help save utility costs.

Building Automation

In commercial and industrial buildings, there are similar (albeit far more robust) systems and protocols used for the same purposes called building automation. Building automation is the automatic and centralized control of a building’s heating, ventilation, air conditioning, security, electrical, and other systems through a Building Automation System (BAS).

Ensuring the accuracy of transducers used in the measurement of room pressure in critical environments is extremely important in order to maintain patient safety. Because the differences in measured pressure are so small (only fractions of an inch of water column) calibrating these devices can be very tedious and usually difficult to perform without the right tools and processes.

In general, there are two industry standard methods of low pressure calibration: hand pump calibration and automated calibration.
