Flow sensor for dusty environments

Schmidt Technology has released the SS 20.500 flow sensor for chemical process applications in dusty environments.

The measurement of flow velocity in dusty environments demands particular sensor requirements. Dirt-tolerant design and easy cleaning are of high importance to guarantee measuring accuracy and repeatability.

Unwanted accumulation of dust and contamination on the sensor tip can be avoided with an optimised aerodynamic flow. This is achieved by the use of the dumbbell-tip sensor.

Due to its wide flow angle (360° axial and 90° radial), the sensor is easy to position in the airflow and the wide measuring range (0.06 up to 35 m/s) lends itself to many applications such as flow measuring in dusty exhaust, air supply control, exhaust air monitoring or drying processes.

As an option, the sensor tip can be protected by a special coating which makes the sensor resistant against salt acids, acetone or sulphuric acid. A plug-in connector makes the sensor easy to install and also quick to replace, and the auto UI function identifies the load resistance and selects the right output signal voltage or current independently.

Information about the current flow velocity and sensor status is displayed directly by four LEDs on the electronics housing.

In order to meet the requirements of explosion protection for gas and dust, the sensor is available in an ATEX version.
