Smart Level Transmitter – Aplisens APC-2000ALW/L Series


  • Programmable zero shift, range and damping ratio
  • 4…20 mA output signal + HART protocol
  • Accuracy 0,16%
  • Local display
  • Intrinsic safety certificate (ATEX, IECEx)

The APC-2000ALW/L level probe is applicable to measure liquid levels in tanks, deep wells or piezometers. The APC-2000ALW/L probe is applicable to measure levels of liquids containing contaminants or suspensions. A typical use for this probe is the measurement of levels of liquid waste in intermediate pumping stations, fermentation chambers, settling tanks etc. Because in submersible part of level probe is mounted only measuring sensor level probe can be use for measurement hot liquids max. 100°C.
