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

Proper Tank Level Measurement Ensures Project Success

Selecting the optimal method to measure liquid tank level is an extremely important decision when starting your project. Making the right choice helps ensure that both vented aboveground and in-ground tanks as well as pressurized tanks work properly. This means that homeowners will receive water for drinking, water will be available to fight fires in remote residential areas, manufacturers will maintain

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.

Are Your Heating and Cooling System Test Stands Compliant?

Recently, the Department of Energy (DOE) released a new requirement that goes into effect on Jan. 1st, 2017 as part of the "Energy Conservation Program: Test Procedures for Central Conditioners & Heat Pumps.” All manufacturers of heating and cooling systems need to ensure that the AHR units they manufacture for residential and small commercial applications meet this new standard.

What is Capacitance?

Capacitance is becoming more integrated in many of today’s applications such as computer memory, condenser microphones, radio receivers, and pulsed magnets. Capacitance is defined as a measure of the amount of potential electric energy that can be stored for a given medium in an electric conductor.  A capacitor is an electronic device designed to provide capacitance in an electrical circuit by providing two conducting electrode plates for storing energy. This technology doesn’t measure the amount of energy stored but rather the potential energy that can be stored. There are various methods of measuring capacitance, generally measured in farads (micro, nano, and pico).

What is the difference between NEMA and IP Rating Systems?

NEMA and IP Ratings both define degrees of protection against substances such as water and dust in electrical enclosures. There are differences however as each rating system is based on different standards (NEMA 250 and IEC standard 60529) and test parameters.

What is Barometric Pressure?

Have you ever wondered why the top results when searching for barometric pressure, are about atmospheric pressure? Barometric pressure refers to the measure of atmospheric pressure, which is the pressure of the atmosphere at the earth’s surface. Both types of pressure can be thought of as the weight of air pressing down on the earth.

Why Do You Need to Calibrate Pressure Transducers?

One of the biggest concerns after pressure transducers have been installed is knowing how accurate the results will be over time. As a result pressure transducers are replaced more often than necessary or are calibrated with outdated technology. Low-pressure transducers used in critical applications require calibration after extended use to ensure
