Determination of the filling level on the basis of hydrostatic container pressure
CrTa sensor in a housing made of PP or PVDF
Available in 2 designs: Suspended sensor/compact version
Pressure range up to 0.6 bar / 6 mWS
Temperature range 0 °C - 70 °C
For pressureless containers
Pressure and temperature sensor HFT
With its hydrostatic measuring principle and the special thermoplastic encapsulation, the HFT allows precise measurements to be performed in aggressive and foaming media. The sensor consists of an integrated pressure and temperature sensor, which is available in a housing made of PP or PVDF. The pressure transducer is shielded from the medium by a nanocoating made of CrTa and by a static seal. It is positioned at the bottom of the container by means of a 7 m long FEP cable. The hydrostatic pressure of the liquid column in the container is continuously measured by the HFT sensor and evaluated by the CPU in the measuring head. For determination of the filling level, the device has to be programmed once beforehand with the volume and density of the respective medium.
In addition to the suspended sensor version, the HFT is also available in a compact version. This version requires an opening in the container base for connecting the system. The compact version can be easily connected to the container or to the outfeed pipes via a DIN union end.
