Ultra-Fast Miniature Pressure Transducer
bandwidth 50 khz / for use up to 180 °c
The piezoresistive pressure transducers Series M5 are ideal, thanks to the M5 fine thread, for
taking measurements at close proximity in places where access is a problem and in very thin
pipes – exactly the kinds of conditions associated with engine test benches. The front-flush
design prevents gas bubbles interfering with fluid measurements and supports measurements
up to 180 °C without a cooling adapter. The extreme dynamic range of 0…50 kHz makes it
possible to record very fast pulsations just as reliably as those associated with static pressure
values. A vibration-resistant Teflon FEP cable (IP67) ensures the 80 mV output signal is routed
securely out of the hot environment and then onwards for processing.
The Series M5 sensor incorporates a stable silicon sensor which is backside-soldered directly
to a supporting element designed for excellent fluid dynamics. This construction eliminates the
disadvantages of sealants, adhesives, separating membranes or capillary tubes in high temperature environments. The practically-flush connection to the measurement media is critical
to the excellent dynamic range of 0…50 kHz. The micromechanical design delivers absolute
measuring ranges of 3, 10 and 30 bar, overpressure protection of up to 5 times measuring range and effective isolation of mounting forces, and a very low dead volume.
