How to use a single Power Supply to power pressure transducers

When installing a pressure transducer system selecting a power supply, may not be one of the first things that comes to your mind. Since a single power supply can be used to power multiple pressure transducers, many regard it as a non-vital task. Nonetheless, it is essential to have the proper configurations between the power source and devices in order for all components to communicate properly and to avoid receiving inaccurate data. Here are some of the best practices we found for using a single power supply to power multiple devices.

Pressure Sensor Calibration for Cleanrooms

Within a building there 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.

How To Measure Velocity And Flow

In HVAC/R applications it is helpful to understand the methods used to determine air velocity. Air velocity (distance traveled per unit of time) is most often expressed in feet per minute (FPM).  Multiplying air velocity by the area of a duct allows you to determine the air volume flowing past a point in the duct per unit of time. Volume flow is generally measured in cubic feet per minute (CFM).

How to Troubleshoot a Pressure Transducer

Pressure transducers today are more rugged and reliable than ever. Made of stainless steel construction, they provide abundant overpressure protection, improved total error band, and offer negligible orientation and vibration effects. They are ideal for long-term use even in harsh environments of extreme temperature, humidity, and vibration.

Can A Room Pressure Monitor Help Me Save Energy?

Monitoring and controlling room pressure in laboratory and healthcare settings can do more than just ensure directional airflow (positive or negative pressure rooms). Proper room pressure also contributes to saving energy. Overpressure or under-pressure scenarios mean that airflow, or even temperature control, are not optimal.

Energy Savings Strategies For Operating Rooms

Operating Rooms consume a great deal of energy, considering the high airflow requirements needed, bright lighting, and significant plug load from patient care equipment. There are, however, strategies to conserve energy and still meet the stringent safety requirements of maintaining positive room pressure. Two conditions need to be met to enable OR energy savings. The first is a method to trigger occupied and unoccupied states. And the second is to act on that state change to setback both temperature and airflow.

Capacitance & Inductive Pressure Sensors

Capacitive Transducers

Setra’s capacitive pressure transducers are expertly designed adaptations of a simple, durable and fundamentally stable device...the electrical capacitor. In a typical Setra configuration, a compact housing contains two closely spaced, parallel, electrically isolated metallic surfaces, one of which is essentially a diaphragm capable of slight flexing under pressure.

Does Your Product Fall Under New RoHS2 Restrictions?

Newly Added Restricted Products Under RoHS2 Affects Manufacturing

In 2013, RoHS2 was created by the European Union legislation, nearly a decade after the original RoHS (Restriction of Hazardous Substances Directive) was implemented.  RoHS2 is merely an evolution of RoHS1 that provides greater clarity on the legal scope of products that should adhere to the hazardous material guidelines. The combination of

The Importance of Maintaining Building Humidity

While it is important to maintain proper relative humidity levels in office buildings for worker comfort and productivity, it is also just as important to maintain proper levels in factories, production facilities and art galleries to protect industrial, commercial and artistic products.
