The pressure sensors in the M5 HB series deliver extremely fast and precise measurements to an accuracy of 0,1 %FS up to 180 °C. The pressure connection to the M5 fine thread is designed for both static and dynamic measurements such as pressure pulses. Their miniature size makes these sensors ideal for local measurements. The sensor’s main attributes are its very low dead volume and its good venting capability. It uses a rear-side technology without a transfer medium that also helps to minimize the attenuation of the measurement signal.
No sealants, adhesives or capillaries are needed either. To prevent any unnecessary impact on flow conditions, the process connection should be as short as possible and, in terms of handling, able to be installed easily even in narrow tubes. The sensor is thus also very lightweight and able to withstand rapid acceleration. The M5 series is available with or without an electronic system. The KELLER Pressure team’s top priority when developing its electronic system was signal fidelity up to the limit frequency of 50 kHz
