flow-captor 4220.1xF/.1xT xx °C
Brand: Captor - Weber SensorsThe flow-captor type 4220.1xF/.1xT xx °C is ideally suited for use in automation processes and other industrial applications where both the flow and the temperature of the medium must be monitored.
The sensor operates according to the calorimetric measuring principle and without mechanically moved parts. The sensor detects the flow velocity and the medium temperature and converts both into electrical signals.
Sensor Heads
The sensor head is constructed of only one piece of electro-polished stainless steel and without any sensor element intruding into the medium. Easy installation by means of T-piece or welded fitting.
For aggressive media special material such as titanium or Hastelloy can be offered on request.
The housing is constructed of glass fibre reinforced PBTP (Ultradur®). The electronics inside is completely epoxy resin encapsulated.
