Each SCHMIDT® Flow Sensor is individually calibrated in a wind tunnel and will be subject to compliance with the specified measuring accuracy. On request, each flow sensor is subjected to after the completion of a review in a calibration wind tunnel and the measured values are recorded in a calibration certificate. This provides the customer for each sensor an accuracy proof and he can use the sensor in applications that are subject to quality monitoring, for example according to ISO 9001:2015 or GMP.
For the creation of high-precision calibration certificates two modern wind tunnels are athome SCHMIDT® Technology available where SCHMIDT® Flow Sensors are measured fully automatically. Both wind tunnels have reference elements that are traceable to national standards. Regular monitoring of the wind tunnels is subject to the supervision of the SCHMIDT® quality assurance system according to ISO 9001:2015.
Atmospheric Wind Tunnel
Very low turbulence and an accurate flow profile are the characteristics of the atmospheric wind tunnel. Its measuring range is from 0.1 to 70 m/s, so most SCHMIDT® Flow Sensors can be measured with it. Even the smallest flow rates, as you are indispensable in cleanroom applications can be exactly reproduced with this wind tunnel.
Pressure Wind Tunnel
With this wind tunnel SCHMIDT® Technology has a unique European balance wind tunnel. This allows standard flow rates of up to 200 m/s are generated, and the sensors are compared and examined under pressure. Its superior flow quality allow reconciliation of the SCHMIDT® High Speed Sensors at the lowest tolerances.
Factory or DAkkS calibration certificate
At the customer SCHMIDT® Technology to each SCHMIDT® Flow Sensor is a factory calibration. Alternatively, we offer to most sensors on a DKD calibration certificate. Please inquire with us. Calibration and expertise already in choosing the right wind tunnel begins the expertise of a manufacturer of flow sensors. All our wind tunnels have been planned meticulously and precisely optimized for your applications. Each new flow sensor from the SCHMIDT® Technology undergoes extensive testing program in the wind tunnel until it is released for use by customers. Behind all this lies a deep understanding of our house on the fluid mechanics of gases and the physical functioning of our flow sensors.
