A small all-rounder – universal and powerful
- Dumb-bell head (largely independent from flow direction, easy to clean)
- Flow velocity and temperature signal
- Probe length 100 … 500 mm
- Measuring ranges 0 … 1 / 2.5 / 10 / 20 m/s
- Optional coated (PU, black)
In many applications, the direct measurement of flow velocity and volume flow in air and gases is the ideal solution. Due to the high demands of modern control technology, the flow sensor has to measure precisely and fast an extremely wide measuring range from "almost zero" up to the maximum value.
- Energy-efficient control of ventilators
- Monitoring filter units
- Regulation and control of flow rate for extraction systems
- Industrial processes
Successor product for SS 20.015 and SS 20.016 (coated version but not pressure-resistant)
