Converting mA to voltage is common in HVAC when working with pressure transducers. Terminology to keep in mind includes:

• 1 mA = 0.001 AMP (short for amperes)
• Amps are referred to as CURRENT
• Resistor values are in OHMS (Ω is the symbol for ohms)
• VOLTAGE is the result of passing amps through a resistor

One of the greatest fears in the general population is the rapid spread of infectious disease. While there are many strategies employed to prevent these infectious diseases from becoming an outbreak, the only way to treat patients without risking the spread of disease is through the use of isolation rooms. Isolation rooms are designed to prevent contaminated particles from spreading beyond a quarantined area by ensuring air is exhausted from the room and filtered through a high-efficiency particulate air (HEPA) filter before it is vented outside of the building.

OEM and mechanical parts suppliers adopting ISO Standards is increasingly common throughout the US, driven by a spike in industry demand for components manufactured in ISO compliant factories. In addition to existing and increasing demand for ISO compliance in clean rooms, healthcare spaces, and laboratories, manufacturing facilities like automotive, electronics, loT, and industrial are now adapting to observe these standards. To be ISO compliant, all of these spaces need highly accurate, reliable, and NIST-traceable sensors for monitoring.

Building automation systems (BAS) are increasingly common in a variety of environments to make HVAC systems as efficient as possible and reduce the need for in-person monitoring of pressure in each area. The value of a BAS relies heavily on a number of components seamlessly integrated together. Pressure transducers that conduct intensely accurate measurements work in tandem with room pressure monitors presenting real-time data and raising alarms if something goes wrong. Calibration equipment ensures building automation tools work smoothly and accurately without the need to oversee them. A BAS can be used in many applications, from filter monitoring to green buildings to zone control in critical environments.

In a hospital environment, alarm fatigue is an increasingly prevalent issue. Alarm fatigue is the sensory overload when clinicians are exposed to an excessive number of alarms; this can result in staff ignoring alarms, particularly if different devices employ similar sounds or frequencies. Nuisance alarms are those not representative of a patient in danger but come from devices that don't allow configuration for non-critical circumstances.

Energy management is a growing practice among companies that operate large buildings, campuses, and other complex facilities. Successful energy management requires detailed information on how energy is being used. However, this valuable information is not available in facilities being actively monitored. For effective energy management, facility engineers need to understand exactly how and where energy is being consumed on their properties.

The goal of any commercial property owner is to attract tenants while also still being profitable. Operating a large building often means having a lot of expenses and other overhead costs, whether they be for maintenance, repairs, utilities, or the multitude of other expenditures any business could incur.

 Technicians at the Kennedy Space Center often work in cleanrooms, laboratories with high degrees of cleanliness provided by strict control of particles such as dust, lint, or human skin. These facilities must be contaminant-free environments where the air is repeatedly filtered and surfaces are smooth to prevent particles from getting lodged.

There are many applications for differential pressure transducers, but none are more critical than those measuring the pressure parameters in a cleanroom. A cleanroom is a critical area used to manufacture medications, containers, enclosures, and other medical devices that require the products to remain sterile from manufacturing through delivery to the customer. The products manufactured in these environments are used to treat and care for the general population and are handled differently than other products.

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.
