You are likely familiar with the task of removing snow that has accumulated on a car or ice that has formed on the windows. The same task is necessary for aircraft when it starts 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 contains 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 known as "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).

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.

Main Features 1. Suitable for pressure measurement of viscous liquids such as ink 2. Suitable for applications where regular cleaning is desired 3. Can be used in food processes if it is a clamp type A typical pressure sensor has a screw at the tip and a diaphragm that receives pressure behind it. If the measurement target 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" and "I need a structure suitable for cleaning since I regularly clean the pressure receiving part." In such cases, the standard structure does not allow visibility into the interior, making it impossible to confirm whether it has been cleaned properly. In such situations, the pressure sensor with a "flush diaphragm" that has the pressure receiving surface protruding is effective. KELLER offers a wide range of products, including a minimum range of 30 kPa and an accuracy of 0.05% FS, and has a wealth of experience. If you are interested, please feel free to consult with us.

FPT Motorenforschung AG is headquartered in Albon, Switzerland, and 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, industrial applications, and marine use, 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 engines on the test bench, we must consider all variables that affect engine 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.

The pressure sensor 35XHT/35XHTT can be used for media temperatures up to 150°C and is suitable for use in bioreactors and autoclaves that require regular sterilization due to its flush diaphragm structure. It achieves an accuracy of ±0.15% full scale (FS) over a temperature range of 20 to 120 °C using a mathematical correction method. The pressure connection of the standard model in the 35XHTT series features a G1/2 flush diaphragm structure. 【Features】 〇 Usable for media temperatures up to 150°C 〇 Standard equipped with two outputs: digital RS485 and analog output 〇 Analog output can be range-adjusted (turndown) via digital RS485 〇 Excellent long-term stability *What is a flush diaphragm structure? Unlike regular pressure sensors that have a screw at the tip with a pressure receiving part behind it, if you want to measure the pressure of ink and need to regularly clean the pressure receiving part, you cannot confirm if it has been cleaned properly since you cannot see inside. In such cases, a flush diaphragm with the pressure receiving surface exposed is recommended!

The high-temperature pressure sensor 35XHTC can be used for media temperatures up to 300°C. It is significantly different from the commonly available pressure sensors that can simply be used at high temperatures, as it achieves high accuracy of ±0.5% full scale (FS) even at a media temperature of 300°C through a mathematical correction method. In addition to a digital RS485 interface, analog current or voltage outputs are available, and scaling settings can be configured via the digital signal. The pressure connection is standard G1/2 male thread (flush diaphragm). *From 2025, the model name will change to 35HTCX. 【Features】 • Can be used at media temperatures up to 300°C, achieving ±0.5% accuracy at 300°C • Standard dual outputs of digital RS485 and analog output • Analog output range can be changed via digital RS485 (turndown) • Excellent long-term stability • Cooling capillary tube structure
