Level, Temp. & Conductivity Measurement
Series 36XW-CTD
The high-precision multi-parameter probes of the 36XW-CTD series measure the conductivity, temperature as well as the depth (pressure) of water bodies. Temperature dependencies and non-linearity are precisely compensated for by means of a mathematical model in the microcontroller. The integrated Pt1000 achieves an accuracy of ±0.1 °C and conductivity can be measured with ± 2.5% of the selected range (0.2 / 2 / 20 / 200 mS/cm). The probes are equipped with RS485 interface. Extended lightning protection is available as an option.
