Flow Sensor for Process Technology


For the employment in process technology the latest SCHMIDT® flow sensor SS 20.260 offers three crucial upgrades compared to his forerunner. With an expanded measuring range of 0 … 50 m/s the sensor can be applied for flow rate control in a wide range of systems. Many processes require the measurement of heated gases and therefore an enhanced operating temperature. De-pending on the configuration of the SS 20.260 it is up to 120 °C. The temperature can be measured with an additional linear output and no separate sensor is required any more. The unit is ro-bust due to a chamber in which the sensing element is protected against impacts ...
