The Sensor measures: Laminar Air Flow & Temp.
Output Signal: 0-10 V or 4-20 mA
Power Supply: 24 Vdc
Sensor for use in: Indoor

The flow transmitter FS5020 detects the laminar air flow and the temperature in air ventilation ducts. The transmitter converts the measurement values into a linear 0-10V or 4-20mA output for further processing.
As an option, a potential-free changeover contact and / or a backlit LCD display are available.
The content of the backlit display can be rotated by the menu in 90 ° increments. The actual value, the set switching threshold, the relay status, the MIN / MAX measured values of the selected interval, etc. can be read off.
The airflow sensor works according to the calorimetric measuring principle and has 5 freely selectable scalings, which can simply be switched over as required by innovative DIP-switch technology.
In addition, the switching threshold, hysteresis etc. can be specified.
