Revenue grade power meters are defined in the American National Standards Institute (ANSI) standard C12.20-2010 Class 0.2. The intention of such a standard is to establish the requirements for power meters so the meters in question accurately and reliably provide monitoring. This ANSI standard has 3 accuracy classes: 0.1, 0.2, and 0.5. These classes correspond to accuracy at full load and include CTs.

Data centers exist all over the world, whether they are dedicated buildings or sections of buildings, and each houses computer servers. In the United States alone there are around 3 million data centers. Out of these 3 million, approximately 3,000 are large data centers while the rest are smaller server rooms in businesses.

In the wake of the coronavirus, it is imperative for hospitals to be prepared for future outbreaks of infectious diseases. For these situations, the safest method for treating patients is isolation rooms. The safety and effectiveness of such rooms is contingent upon proper control of the room's differential pressure.

Power meters measure utilities like electric, gas, or water to increase building performance. With a power meter, users can get granular data on the use of energy of a building. Such granularity can reveal any equipment or systems adding to energy waste. Submeters can be used in any type of building, from manufacturing to apartments. Meters make it easy to visualize and optimize energy usage.

During a disease outbreak, there are several risks dentists encounter. One serious risk is contracting an illness from aerosol particles created during a procedure. Aerosols are splatters, mists, or droplets in the air, and can include saliva, blood, and plaque. Three main sources of airborne contamination in dental offices are dental instrumentation, saliva and respiratory sources, and the operation site. Aerosol particles can be generated with:

It is paramount for schools to put safety first as students prepare to return amidst all the concerns of the coronavirus. An isolation area, separate from any other spaces in the school where medical care is provided, means students displaying symptoms can safely remain isolated until they are picked up.

In the wake of the coronavirus, it is essential schools create the safest possible environment before students return. One of the ways to do this is to provide a COVID-19 Related Isolation Space for students displaying symptoms. This isolation area is separate from the nurse's office and any other space where routine medical care is provided. In a negatively pressurized space like this, students with symptoms can safely remain isolated until they are picked up.

Pressure transducers all have some degree of variation in output caused by changes in temperature. The best way to compensate for such variation is to employ components on the PCBA that respond to temperature. These components can be fixed in value, adjustable like a potentiometer, or feed into a digital circuit.
