PRODUCTS :: :: Flow | Thermal Flow Sensor TA10 |
The principle of measurement is based on heat transport from an electrically heated body in ambient medium dependent on the relative velocity between both. Höntzsch thermal flow sensors TA designed as TA10 probes and measuring tubes TA Di... use a thin-film sensor element. Thin-film sensor elements consist of an electrically heated Ni-resistor and a Ni-resistor temperature probe. The medium temperature and the temperature difference Dt between the heated Ni-resistor and the medium are the dimensions for the flow.
