The WIKA LH-20 submersible pressure transmitter is designed for the most demanding of level measurement tasks. A slender design, highest accuracies, low temperature errors and an adjustable measuring range ensure the suitability of the LH-20 for all submerged level measurements. The WIKA LH-20 submersible pressure transmitter can adapt to countless applications and measuring media through a large number of features and options. Depending on the requirements, this level probe is available with, amongst other things, a titanium case, PUR/PE/FEP cable, 0.1 % accuracy, HART®, scaleability or parallel temperature output signal. For operation in hazardous environments, the LH-20 submersible pressure sensor is also available in an intrinsically safe version. For potable and fresh water applications, a potable water conformant product variant is possible in accordance with KTW and ACS. The WIKA LH-20 submersible pressure transmitter has been engineered for use in the harshest environments. Through a double, redundant sealing concept, it is permanently hermetically sealed. A robust design from stainless steel or titanium, with a spring-reinforced cable seal, ensures a long service life, even under the big mechanical loads of installation and continuous use. Designs with the highest media resistance using FEP cable and titanium cases, along with the integrated lightning protection, guarantee the longevity of the submersible pressure transmitter even under the most adverse environmental influences in aggressive media, in both indoor and outdoor use.

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.
