JUMO MAERA S28

Hydrostatic level gauges, Pressure sensors

Fields of application

JUMO MAERA S28 is a submersible hydrostatic level transmitter for continuous liquid level measurement in open and ventilated tanks, wells and water systems. The stainless steel measuring system, integrated surge protection and IP68 housing allow the sensor to be used in harsh industrial and outdoor conditions. The measuring height ranges from 2.5 to 100 mH₂O.

Features:

  • Measuring height 2.5–100 mH₂O
  • Piezoresistive silicon measuring element
  • Accuracy up to ±0.2 %
  • Integrated surge protection
  • Stainless steel body and membrane
  • IP68, submersible up to 100 m
  • Integrated Pt100 temperature sensor available
  • Suitable for indoor and outdoor installation
