VTL 20 Turbine Flow Sensor

VTL 20 Turbine Flow Sensor

7811

The SIKA VTL 20 turbine flow sensor is made for flow measurement or dosing applications for liquids. Because of the very compact design, the extensive measuring range and the convincing precision of measurements, almost unlimited applications are possible. The sturdy bearing materials – sapphire and tungsten carbide – also guarantee an exceptionally long endurance. The liquid flowing into the SIKA VTL 20 turbine flow sensor is split into individual jets by the guiding blade. These jets hit the rotor evenly from different directions, setting the rotor in motion. The rotation speed of the rotor is then converted to an electrical pulse signal (frequency): The rotor is fitted with magnets and a Hall effect sensor detects the rotation of the rotor. A flow-proportional frequency signal (square-wave signal) is made available. The construction of the guiding blade and rotor enables to realize the very low start-up flow values.

RLS-2000 Float Switch

RLS-2000 Float Switch

8114

The WIKA RLS-2000 float switch is a reliable and inexpensive float switch made of high-quality plastic. The WIKA RLS-2000 float switch is particularly suited for measuring the levels of aggressive and corrosive media, such as bases and acids. For cost-sensitive applications such as the monitoring of levels or overflow and dry-run protection, float switches are an ideal solution. The WIKA RLS-2000 float switch detects the level using a permanent magnet and frictionless reed contacts at up to 4 defined switch points, without contact and thus free from wear. Integration as a limit level switch is simple, convenient and fast, because no adaptation or calibration is required during installation. The robust design minimises service and maintenance costs.
