Should Your Sensor Have A Connector Or Pin Terminals?
When it comes to measuring the activity of your project, it’s nice to have options. High precision sensors can offer plenty of selections from the range of your measurements to the output of your readings, but a sensor is only as good at its connection. Connectors and pin terminals are common and dependable connections that relay your readings from within the sensor to the screen in front ...

Determining the Right Cable Length and Output for a Sensor
If you’re monitoring a bridge or automating a machine, a high precision sensor is a great solution, but it’s no good if the output signal can’t reach the data logger. Depending on what you need to measure and what environment you’re in, determining how long your cable must run can be crucial. High precision sensors offer three common output types: analog, digital and ...

Greenhouse gas mitigation in the EU: An overview of the current policy landscape
In 2009, the European Union (EU) pledged a unilateral greenhouse gas (GHG) reduction target of 20 percent below 1990 levels by 2020, rising to 30 percent if “other developed countries commit themselves to comparable emission reductions” (European Council 2009). The EU’s GHG target forms one pillar of a so-called 20-20-20 package that, in addition to the 20 percent GHG reduction, ...

Process gas mass flow controllers - An overview
A mass How controller (MFC) is used 10 control the How of gases in a wide range of microelectronic processes. A well-designed MFC maintains a constant tlow within I percent of the full-scale flow, has a repeatability of 0.2 percent of full scale, and has a response time of 1 second to reach within 2 percent of the desired (command) flow, all of this is in response to any changes in command flow. ...

How Does Recycling Reduce Air Pollution
Recycling has a profound impact on reducing pollution levels. Using recycled materials instead of raw, new resources, we diminish the harmful emissions of extraction and manufacturing. For example, the mining and refining aluminium from bauxite ore is highly energy-intensive and results in significant greenhouse gas emissions. In contrast, recycling aluminium requires only 5% of the energy ...
