Pressure Sensor Hits The Rails With Safety Certification

Baumer’s PP20R family of pressure sensors offer high insulation strength and enhanced EMC immunity, while also being, according to Baumer, the only pressure sensor on the market right now to be labeled in accordance with the GS1 standard. The PP20R measures relative pressure in pressure ranges from 0 to 0.25 bar and 0 to160 bar. It is available in a variety of models about accuracy, output signal (current 4 to 20 mA and voltage 0 to10V, 0 to 5V, and 0 to 2V), and electronic and process connections.

 

The sensor is suitable for use in applications such as pressure measurement in braking systems, cooling systems for traction units, and controlling and regulating the pantograph contact pressure. Insulation strength is up to 1.5 kVac, which minimizes the risk of damage caused by voltage differences in the device, thereby increasing both its own operating safety and that of the entire system. Additionally, its high electromagnetic immunity exceeds the requirements set out in the EN 50121-3-2 standard, meaning it can even be positioned close to electronic interference fields without a problem.

With its four pressure equalization ports in place of the single equalizer found in other products on the market, the PP20R is less vulnerable to environmental dirt, deposits, condensation water, and other liquids. This also makes it ideal for outdoor applications in harsh weather conditions, including on vehicle roofs or even in underfloor areas. For more insights, checkout the datasheet.
