Pressure Level Transmitter

The 36 Xi W series is built on the latest-generation microcontroller platform, which KELLER has developed to meet extremely high precision requirements and increase compatibility with a wide variety of interfaces. Along with pressure (level) information, digital interfaces also transmit other water parameters such as temperature and conductivity.

The 36 Xi W series is based on the proven KELLER 36 X W series using the high-quality 10 L-series pressure transducer. All series X pressure level transmitters feature an RS485 interface, which provide pressure and temperature standard, while versions requiring higher accurately, temperature or conductivity sensor are available options. Multi-parameter probes fitted with pressure, temperature and conductivity sensors (CTD – conductivity, temperature, depth), are approximately 90 mm longer.

  • Pressure sensor: resolution 5 ppm
  • Mathematical compensation of nonlinearities and temperature dependencies
  • Sturdy stainless steel housing (titanium or Hastelloy also available)
  • Extended lightning protection fitted to the SDI-12 interface as standard
  • Level measuring ranges from 0.3m to 300m. Higher ranges are possible using a Sub-Conn® connector
  • Ultra-high long-term stability
