Silicon Flow Sensor with ultra-fast response time and low power consumption

The Silicon Flow Sensor (SFS) is IST AG’s first flow sensor based on silicon technology and extends the IST AG flow portfolio. The SFS is made for gas flow and it is IST AG’s fastest flow sensor with a response time < 5 ms.  

It is operated according to the calorimetric principle and can therefore detect not only the flow velocity but also the flow direction.

The symmetrical design of the SFS flow sensor allows an easy interpretation and evaluation of the measurement signal. The sensor can be used in different gases. It is characterized by a high sensitivity, a very fast response time and an extremely low energy consumption.

IST AG offers the full range of cooperation, from support with the customer's system integration to pre-assembled, customer-specific partial solutions and a complete solution tailored to the customer's application.

The SFS01 is particularly suitable for low flow velocities up to 3.5 m/s (in gases). It shows very fast measurement results of the flow rate as well as the flow direction.

The Silicon Flow Sensor SFS01 offers three main characteristics:

  • Very fast response time <5 ms
  • Very low energy consumption
  • Easy system integration including temperature compensation

Well-adapted channel geometries allow the performance of the sensor to be optimally aligned to the desired application. The SFS01 flow sensor is ideally suited for space-limited applications but can also be easily upgraded to complete ready-to-use systems.

Suitable application areas for the SFS01 flow sensor are flow measurements in battery-operated / portable devices, air conditioning technology (HVAC), automation technology as well as process and control engineering.
