Stainless Steel Overfill Protection Probes

 

Liquip’s LDP200 Series Stainless Steel Overfill Probes are used in overfill prevention systems on road tankers and storage tanks to detect the presence of a liquid at a defined level.

The probe’s stainless steel body and FFKM seals provide superior resistance to chemical corrosion, making them well-suited to Petroleum as well as Chemical Industry applications.

The LDP200 Series Probes are compatible with industry standard signal formats (EN 13922), providing interoperability with both Liquip’s existing Gantry Monitors and other compliant Monitors.

Liquip can supply LDP overfill probes as single units or in "Kits". A Kit is a part that combined two or more parts e.g. an LDP probe supplied with an extension and O-ring. Please see ordering information tab for further details on available kits.

Features & Benefits
  • Stainless steel body and FFKM seals provide superior resistance to chemical corrosion.
  • Compatible with industry standard signal formats (EN 13922)
  • A visible optic light in the sensor tip indicates whether it is dry and operational.
  • Independent visual test for function when in or out of the tanker.
  • Patented visible light - Technological breakthrough.
  • Glass prism is light-shielded by the retainer.
  • Probe can be removed from tank top without having access to interior to remove a hood.
  • Construction is fully sealed front.
  • Self healing epoxy at rear on cable entry.
  • Fully potted construction.
  • Range of probe extensions to suit various probe lengths.
