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

LEVEL PROBE FOR HIGH LEVEL – LP-H

Better Level Sensing…

  • Rugged. Polypropylene float guard protects float switch from physical abuse.

     

  • Chemically Resistant. All polypropylene wetted parts plus PTFE float switch.

     

  • Built for rough, wet and corrosive environments.

     

  • Easy Depth Adjustment by hand with cord grip.

     

  • Shielded cable connects to Gizmo alarm boxes or PLCs.

LIQUID LEVEL PROBE is perfect for mounting in tanks with very low headroom.  The only part that extends above the tank is the cord grip.  Various ways to mount it: the 1″NPT cord grip can fit into a threaded tank bushing, or our rim-mount bracket. 

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 PTFE float switch is N.O. or N.C. and the switch is reversible.  Includes 10 ft of 0.031″ wall shielded communications cable to connect to your process. 

OPTIONS

Waterproof circular connectors 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, PTFE float, and have a polypropylene screen and retaining pieces. 1/2″ NPT female elbow to connect various tubing fittings into.

LP-KF (Kynar) models are made from Kynar pipe, PTFE float, and ETFE screen which is retained with Kynar fittings. The top cord grip is Teflon. The standard construction has a tubing fitting in a specific size that you order and is not freely interchangeable like the polypropylene models.  This reduces the price dramatically.

LEVEL PROBE WITH ALARM BOX

Polypropylene pipe and PTFE float switch are resistant to most chemicals at room temperature, including:

  • Aqueous Ammonia (conc.)
  • Aqueous solutions to 100°C
  • Chromic acid (50%, Rm. Temp)
  • Glycolic acid
  • Hydrochloric acid (conc.)
  • Nitric acid (30%)
  • Oils (including waste oils)
  • Potassium carbonate (40%)
  • Polyester resin (viscous)
  • Sodium hydroxide (50%)
  • Sulfuric acid
  • Sodium Hypochlorite

For highly aggressive applications we offer a PVDF pipe with the same PTFE float switch which is suitable for temperatures up to 275 deg. F   [135C]  The upper temperature limit will depend on the chemical.  Refer to the chart here
