PROBE FT25 – WITH INTEGRATED TEMPERATURE SENSOR PT100 – WITH CONNECTION CABLE
 Cylindrical vane wheel sensor / insertion probe with integrated temperature sensor Pt100 for combined measurement flow/temperature and probe diameter 25 mm.
 Probe materials: aluminium, stainless steel or titanium.
 Working temperature range up to +260 °C.
 Suitable for fixed measuring of actual flow velocity v [m/s] and flow rate V/t [m³/h, l/min] in clean gases and liquids, briefly also in particle-laden mediums. They are extendable and therefore practical for applications in smoke stacks, etc.
 Signal evaluation with handheld unit flowtherm NT, transducer UFA and system units.
