Differential pressure characteristics can be visualized in a software using HM 170.55.
HM 170.55 consists of a measuring amplifier with 18 pressure sensors. One of the sensors measures the reference pressure. Up to 17 pressure sensors are connected by hoses to an accessory in the wind tunnel HM 170. The measured values are transmitted directly to a PC via USB where they can be analysed using the software included. The software displays simultaneously the differential pressures of the pressure measuring points and the reference pressure.
HM 170.55 is recommended as an accessory for experiments on pressure distribution on aerofoils HM 170.22, HM 170.26, HM 170.27, on pressure distribution on a cylinder HM 170.23 and for experiments on wake measurement HM 170.28. Additionally, HM 170.55 is suitable as accessory for all experiments with differential pressure measurement.
The software detects automatically if the system for data acquistion HM 170.60 is also used. In this case, the software of HM 170.55 also indicates velocity and angle.
