SS20.250
Flow sensor
For ventilation, air-conditioning, cleanroom and pharmaceutical applications.
In many applications, direct measurement of the flow velocity and of the volumetric flow in air and gases is the ideal solution. Owing to the high requirements in modern control technology, the flow sensor used must be able to detect precisely and quickly over an extremely wide range from almost zero to the maximum value.
Typical applications of the Flow Sensor SS 20.250 dumbbell head technology include:
Monitoring and energy-efficient control of fans
Continuous monitoring of filter units
Safe control of the volumetric flow of extraction units
Monitoring of the laminar flow in cleanrooms
The smallest all-rounder
Thanks to its compact mechanical design, the SS 20.250 can be installed very easily via a flange or a compression fitting. Its complete electronics are housed in the robust metal sensor tube, which has a diameter of only 9 mm.
