Pressure measurement - Import export

Apparatus for pressurizing test pieces We offer burst test benches to test load-bearing elements under pressure for their resilience. The components to be tested are put under pressure until they burst. Depending on the requirements (e.g. depending on the medium, pressure range, static or pulsating tests) we build your customized test stand.

The high-precision calibration laboratory is accredited according to DIN EN ISO/IEC 17025 for flow calibration of flowing gases. The EP calibration laboratory is accredited by the DAkkS according to DIN EN ISO/IEC 17025:2005 for calibrations of gases in-house and on-site under the procedure number D-K-21444-01-00. We offer calibrations for gas flow measurement as well as temperature, humidity and pressure measurements. In addition, we calibrate all measured variables of the test bench directly at your site. Our experienced technicians also check the harmonious interaction of all sensors, so that the entire system is perfectly tuned. The opening of our new calibration laboratory in Asia enables us to offer you even better service internationally.

The particle image velocimetry (PIV) is an optical noninvasive working flow velocity measurement method. The flow field is made visible by introducing into the fluid small buoyancy neutral particles – the so called tracers. The particle flow then is illuminated with the aid of a light sheet and recorded at two defined different times within a small time interval with a digital camera. Because the particle move within this time interval with the flow, one can calculate the particles velocity by knowing its path between the two moments of illumination. The result is a velocity vector field of the flow. Here, we assume that the particles are small and follow the flow without any slip. Compared to local methods like LaserDopplerVelocimetry (LDV) with the ParticleImageVelocimetry one can reconstruct a whole flow region An extension of ParticleImageVelocimetry is the combination of PIV with thermometry (PIV/T).

The Suvis GmbH offers flat pressure sensors (see photograph), which we produce ourselves and which can be used for classical static pressure measurements on solid surfaces like automobile frames. The flat pressure sensors are applied especially in cases where one cannot place a borehole in the respective surface. Hence, flat pressure sensors represent “transportable” static pressure boreholes, which one can glue on the surface of the flow body. The photo shows typical flat pressure probes. Typical dimensions are 17 mm (diameter of the flat disc) and 0,5 mm as diameter of the pressure borehole. The disc consists of bronze, while the measurement tube is made of high quality steel. In order not to interfere with the flow the discs are chamfered around their periphery. When producing the flat pressure sensors for you we can take your individual design requests into account.
