How Power Meters Work

Power meters are used in a wide variety of applications to measure electricity use on a more granular level than the main utility meter. Power meters, or submeters as they can sometimes be referred to as, can tell you where, how, and how much electricity is being used in the building.

Why use I2C communication with your transducer?

I2C stands for an integer-integrated circuit. This is a commonly used communication protocol that is flexible enough to be used for a wide variety of applications. Specifically, I2C is a serial communication method with bi-directional two-wire communication. Any sensors and secondary devices only communicate when asked to by the primary.

What are Revenue Grade Power Meters?

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.

What are Power Meters?

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.

Ensuring Safety in Dental Offices

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:

Creating Isolation Spaces in Schools

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.

Keeping Schools Safe from COVID-19

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.

How to Thermally Compensate a Sensor

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.
