Keller Company Ultra High-Speed/High-Temperature Pressure Sensor M8coolHB
Media temperature up to 1000°C compatible, optimal for measuring pulsations and unsteady behavior with a bandwidth of 50kHz, built-in amplifier (0-10V output) high-precision pressure sensor.
The ultra-high-speed pressure sensor M8coolHB can measure not only static pressure but also pressure changes within a bandwidth of 0 to 50 kHz. This is achieved by the digital circuit continuously adjusting the analog signal in real-time, with an output of 0 to 10V. The compact sensor head with M8 fine thread can be used at temperatures up to 1000°C due to cooling, and it has a pressure resistance of up to five times the maximum measurement range. It also has excellent vibration resistance. 【Features】 • The sensor head is heat-resistant up to 200°C and can be used at media temperatures up to 1000°C with cooling (air-cooled or water-cooled) • Output is an analog signal of 0 to 10V (with built-in amplifier) • Internal cooling channels function more efficiently than conventional cooling adapters • Wide temperature compensation range: -40 to 180°C • High-speed response up to 50kHz, ideal for measuring dynamic pressure (e.g., pulsations and unsteady behavior) • Resistant to the effects of vibration and shock • Pressure connection uses M8×0.75 fine thread, very compact size • Teflon FEP cable with IP67 ferrule, perfect for engine test bench applications • Pressure range: 300kPa, 1MPa, 3MPa (absolute pressure)

What is high-speed measurement in pressure measurement? Dynamic characteristics of sensors.
Many applications today require not only accurate measurements but also fast measurements. In this context, the dynamic behavior of sensors becomes particularly important in addition to measurement accuracy. While the limiting frequency of electronic circuits, sampling rates, or similar parameters are often recognized as decisive factors, this is actually just one aspect, and it is necessary to consider the entire sensor system. How much speed is required from the sensor? What are the factors that truly affect the dynamic characteristics of the sensor? I will explain why not only electronic circuits but the entire sensor design is important. I will introduce typical application examples that require millisecond-level speeds, provide findings from test results, and assist you in selecting the optimal sensor according to your needs.

Viewing Engine Performance - Pressure Sensors for Engine Test Benches
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.
