Product Introduction
Swiss IST Thermal Mass Flow SensorFS7 Suitable for a variety of gas flow applications, temperature resistance up to 150 °C
Swiss IST Thermal Mass Flow SensorFS7 Description:
The IST AG FS7 flow sensor is the successor to the FS5 flow sensor, featuring a symmetrical heater design with enhanced sensitivity. The FS7 flow sensor is suitable for gas applications and offers excellent long-term stability. The FS7 sensor has a low thermal mass, resulting in a short response time. In addition, the standard FS7 sensor is equipped with a housing, making it easy to use in various applications.
