Level Detector  Manufacturers, Traders, Suppliers

PTL Hermann GmbH develops and manufactures vibration type level switches for detecting the presence or absence of powdered or granular solids that are stored in all kinds of silos, hoppers and containers. The products get distributed worldwide.
Principle of operation:
a vibrating system gets forced to vibrate on its resonance frequency by a piezo crystal drive. If filling material, (bulk solids), covers the vibrating blade of the probe, its vibration gets damped. This is sensed by the electronic circuit and the output switches. When the blade gets uncovered due to declining level, the instrument restarts to vibrate and the output switches back.

Product Overview

CV600/CV660
Low-Cost vibrating level switches for grained and granular solids with minimum densities of 20 grams/litre (CV660: 50 grams/litre) and max. grain sizes of 10mm. Process connection 1", insertion length 157mm
SHT 120/130/140
Vibrating level switch for powdered and granular solids with high process temperatures up to 250°C. Process connection 11/2", insertion lengths 184mm up to 4m.

The instruments can be used for overfill protection, for high or low level alarm and in a special configuration for the detection of interfaces, e.g. sand that has settled in water (special model SEDIMENT).
The unique, patented single rod designs of our instruments make them work perfectly and reliably even at critical applications where conventional products cause problems due to bridge building, material build-up or rat holing.

Liquiphant FTL33 is a point level switch for liquids. The FTL33 is especially designed for food & beverage applications where hygienic requirements are requested. The Liquiphant is used for overfill prevention or pump dry-run protection preferably in storage tanks, mixing vessels and pipes.Compact:
