Submersible level sensor

  • Accuracy 0.5% or 0.25%
  • For measuring levels in liquid media
  • Model PEX12 Ex classified according to ATEX, FM, CSA
  • Pressure range from 0…0.1 bar to 0…25 bar

Product description

Submergible level sensor for, for example, measuring levels in tanks. The sensor is submerged in the media and reads the pressure in relation to the depth. For example water at a depth of 1 metre corresponds to 0.1 bars pressure. If media other than water is used, the calculation has to be made using that media's density when receiving the analogue signal that the level sensor gives. Up to 50 metres depth. For media that are compatible with stainless steel type 316Ti. Model PEX12 is Ex classified according to ATEX, FM and CSA and is intrinsically safe for zone 1 and can be supplied with option for zone 0.
