Stability is defined as a change (or lack of change) in accuracy over a period of time.
Drift is commonly used as a specification to illustrate the stability, or change in accuracy over a period of time, commonly shown as X%/year where X = a number; i.e. 0.25%/year. In this scenario, a device with a ±1% accuracy, would be expected to have an accuracy of ±1.25% (1%+0.25%) after a period of one year. Depending on the design, brand, and range of the sensing instrument, the stability can vary widely. Continue reading “What is Stability and Why is it Important?”
Room pressure monitors are devices that monitor differential pressure between two rooms or areas. Differential pressure is the difference of two pressures being sensed.
There are several applications where it is important to maintain a pressure difference between two rooms. This helps to ensure that there are no contaminants entering or exiting a protected area. In a medical setting, an isolation room requires a pressure differential to make sure that no bacteria, pathogens, or viruses enter (or leave) the isolation room. This protects healthcare professionals, patients, and other guests, and minimizes the spread of germs. Room pressure monitors would also be used in areas such as: pharmaceutical manufacturing, semiconductor manufacturing, clean rooms, research labs, vivariums, and clean manufacturing areas.Continue reading “What Are Room Pressure Monitors and Where Are They Used?”
What are the differences between pressure transducers and pressure transmitters?
Many readers have likely heard the terms transducer and transmitter used interchangeably without much confusion. When searching the internet for either term, search engines provide nearly identical results. Are there any differences? The short answer is “yes”. Continue reading “Pressure Transducers vs. Pressure Transmitters”
Electrostatic discharge (ESD) is a unique phenomenon that can be seen in everyday life. The effects of ESD can be seen by rubbing a balloon on your head, resulting in your hair sticking to the balloon, or by touching a doorknob or a pet in a dry building and receiving a static shock.
