Description
SS 20.100 is a high-quality and affordable flow and temperature sensor for air and gases. The sensor is housed in a compact and convenient case and features a universal sensitive element that measures airflow in any direction. This eliminates the need to align the sensor with the flow.
The sensor comes with a mounting bracket that allows for easy and quick installation of the device in two different ways. Thanks to the extension mounting tubes, it is possible to adjust the maximum immersion depth of the sensor, which also allows its use on pipelines with large diameters.
The sensitive element is fully enclosed in a metal housing, making the flow meter resistant to dust ingress. Additionally, in case of contamination, the sensitive element can be easily and quickly cleaned without fear of damaging the device.
All these advantages make the SS 20.100 suitable not only for HVAC (heating, ventilation, air conditioning) applications but also for clean rooms, for example, for precise air control in fume hoods.
Advantages
- Easy installation, no need for flow alignment, adjustable immersion depth, probe length extension;
- All electronic components are built into the device probe;
- LED status indication;
- Durable and stable – maintenance-free;
- Easy to clean (dust resistant).
