The basic principle of piezoresistive pressure measurement is the same as that of resistive pressure measurement, which captures changes in resistance. However, what are the advantages of using piezoresistive elements? This also explains not only the benefits of piezoresistive technology but also the aspects to be cautious about.

Removing and capturing CO2 from the atmosphere in a practical and cost-effective manner is a challenging task, but we will introduce examples of manufacturers that are conducting research and development based on solar cell materials. They have successfully achieved CO2 capture at low power consumption and dramatically reduced CAPEX (capital expenditure) costs. This company has also significantly reduced energy consumption, realizing a cost-effective DAC technology. Why has Keller's high-precision pressure sensors come to be used in that process? We will reveal the secret! (Available for download from related catalogs)

You are likely familiar with the task of removing snow accumulated on cars or ice that has formed on windows. The same task is necessary for aircraft when it begins to snow or ice forms. The process of removing ice or snow from an aircraft is known as de-icing. De-icing is performed in specially designated de-icing areas and is scheduled just before the aircraft takes off. This is because ice and snow not only increase the weight of the aircraft but can also impair its aerodynamic characteristics. De-icing is carried out using a liquid that consists of at least 50% glycol mixed with water, and there are a total of four types of liquids that can be used for de-icing. At Amsterdam's Schiphol Airport, the mixture used for de-icing is stored in large heated tanks and is pumped into what is called "Safeaeros" before being used on the aircraft. Safeaeros is a type of spray vehicle specially developed for this purpose. At Schiphol Airport, four Safeaeros vehicles are used per aircraft (two in front of the main wings and two behind the tail).

When selecting a pressure sensor, there is a type with a flush diaphragm structure. What are its advantages? Main features: 1. Suitable for measuring the pressure of viscous liquids such as ink. 2. Appropriate for applications where regular cleaning is desired. 3. Can be used in food processes if it has a clamp type. A typical pressure sensor has a screw at the tip, with a diaphragm (partition) that receives pressure located behind it. If the medium being measured is air, there is usually no problem with the standard structure. However, there are inquiries such as "I want to measure the pressure of ink" or "I need a structure suitable for cleaning since I regularly clean the pressure-receiving part," and in such cases, the standard structure does not allow for visibility of the interior, making it impossible to confirm whether it has been cleaned properly. In such cases, the pressure sensor with a flush diaphragm, where the pressure-receiving surface is exposed, proves effective. KELLER offers a wide range of products, including a minimum range of 30 kPa and an accuracy of 0.05% FS, with a wealth of experience. If you are interested, please feel free to consult with us.

Pressure Measurement Under Severe Conditions FPT Motorenforschung AG, headquartered in Albon, Switzerland, develops engines for vehicles and machinery in the powertrain division of CNH Industrial. Approximately 220 staff members are on-site developing new FPT products for commercial vehicles, construction machinery, agricultural machinery, and industrial and marine applications, with engines being tested on a total of 30 test benches. To measure engine efficiency, FPT Motorenforschung uses tools such as the M5 series pressure sensors from KELLER, a specialist in pressure sensors based in Switzerland. "The engines we develop and test in the factory meet the most stringent quality requirements in terms of materials, emissions, and efficiency. This means that when inspecting the engines on the test bench, we must consider all variables that affect the engine's performance. Therefore, precise measuring instruments are required to obtain accurate and reliable measurements, even under special conditions inside the engine," said the head of the Testing Engineering/Electronic Measurement Department at FPT Motorenforschung AG.
