ECL 8439 – Submersible Pressure Transmitter

The Submersible Pressure Transmitter ECL is based on Trafag’s own thick-film-on-ceramic technology. Together with the inhouse developed high performance ASIC chip electronics it ensures a high level of accuracy over a wide temperature range.

  • Suitable for thick and viscous media
  • Different materials for optimum media compatibility
  • Lightning protection integrated
Applications: Process technology, Water treatment (wastewater, grey-water, drinking water), Seawater, Level of oils and fuels
