Level Probes – Float Switch

The LEVEL PROBE contains a float switch mounted in the bottom of an adjustable polypropylene pipe.

Better Level Sensing…

  • Rugged. Polypropylene float guard protects float switch from damage.
  • Chemically Resistant. All polypropylene wetted parts plus PVDF cable seal.
  • Built for rough, wet and corrosive environments.
  • Easy Depth Adjustment by hand – simply slide through the cord grip.
  • Shielded cable connects to Gizmo alarm boxes or PLC or other monitoring devices.
  • Complete immersion models
  • Reversible float switch.

LIQUID LEVEL PROBE

These are a float switch level sensor proteted inside our float guards. Maintains the exceptional reliability of float switches while eliminating the primary cause of failure. These detect liquid level and the electronics are a distance away in an electronics enclosure.  These solve a few problems for tanks with very low headroom, or for very tall tanks it brings the electronics down to operator level.  Also, immersion models can go in a small space – only 1″ in diameter.  The only part that extends above the tank is the cord grip. 

Depth adjustment is easy and can be done by hand by loosening the cord grip and sliding the probe to the correct depth. When tightened, the cord grip provides a waterproof seal.

The output from the float switch is N.O. or N.C. and the switch is reversible.  Includes 10 ft of thick wall shielded communications cable to connect to your process. 

There are various ways to mount them: either the 1″NPT cord grip can fit into a threaded tank bushing, or our rim-mount bracket. 

OPTIONS

Level probes are intended to be used with our Alarm Boxes.  Battery-powered AB-1 or AC powered AB-2R or IS-AB for Hazardous Locations.

Waterproof circular connectors on the end of the cable makes repeated disconnections easy.  When connected to our alarm boxes, two of the conductors are configured in a loop to detect if the cable is missing.

Our level probes can still function successfully in dirty liquids with the addition of a screened float guard. 

MODELS

LP-PF (polypropylene) models are constructed from polypropylene pipe, polypropylene float. Tank mount is PVC with 1″ NPT thread. It is possible to have multiple floats at different levels on one pipe

LP-KK (Kynar) models are made from Kynar pipe, Kynar float, and PVDF cable seal.  Only one float switch per pipe is possible.

This page shows our float switch level probes only. We also have probes with capacitance sensors for dirty liquids that coat or foul float switches.  

For very tall tanks where a rigid level probe would be impractical, we also offer Immersion level probes. These are probes suspended from the top of the tank by a PVDF cable. Datasheet. Contact us for more information and ordering.
