KELLER Series 36XiW Pressure Level probe

Product Description

The high-precision level sensors of the 36XiW series measure with ultra-high accuracy and resolution. Temperature dependence and nonlinearity are precisely compensated for in the microprocessor by means of a mathematical model. They can be supplied with either an RS485 or SDI-12 interface. In addition to the pressure sensor for the level measurement, it is also possible to integrate a Pt1000 that is calibrated to ±0,1 °C from 0...50 °C. Extended lightning protection comes as standard with the SDI-12 interface and is available as an option for the RS485 interface.

RS485 Robust interface with differential gauges, for lines up to 1,4 km in length. Modbus RTU and proprietary KELLER bus protocol
SDI-12 Standard interface for environmental monitoring, ideal for battery operation

The 36XiW series is based on the proven KELLER 36XW series using the high-quality 10L-series pressure transducer. All series X pressure level transmitters feature an RS485 interface, which provide pressure and temperature standard, while versions requiring higher accuraty, 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.
