Model LF-1 Submersible Pressure Sensor

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
Extensive test cycles not only guarantee a permanent resistance and long service life in all commonly used oils and fuels, including aggressive crude oils and biofuels, but also in flowing and stagnant waters and in wastewater treatment applications.
Features
  • Suitable for measurements in contaminated and aggressive media
  • An optimised discharge behaviour and a large pressure port prevent the instrument from clogging and ensure a minimum maintenance effort
  • Can be used in explosion-protected areas
  • Developed for wireless applications
