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.

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?

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

What does shock and vibration do to a pressure transducer?

There are numerous environmental factors that can interfere with the performance of a pressure transducer.  Two commonly overlooked factors are shock and vibration. Knowing the system where the pressure transducer is installed can help avoid high shock and vibration conditions, minimizing premature failure of your instrumentation.

How are power meters used in LEED projects?

LEED, the Leadership in Energy and Environmental Design, is the largest driving force behind the increased development of green buildings in the world. One of the most important factors that LEED uses in their certification process is energy consumption and the owner’s ability to track usage and identify potential savings. While most conventional buildings have simple meters provided by the utility company for billing purposes, the advanced standards for LEED certification require more robust and more precise monitoring capability.
