Application
Liquiphant T FTL20 is a point level switch for all kinds of liquids; it can be used in storage tanks, vessels and pipes.
It provides overflow protection or pump protection in cleaning/filter systems and in tanks for refrigerants or lubricants.
The FTL20 is unaffected by medium conductivity, buildup, turbulence, flow or bubbles, and is an ideal replacement for float switches, conductive and capacitive sensors and optical sensors.
The FTL20 is not suitable for hazardous areas or media temperatures above 150 °C. The FTL20 can also be used in hygienic applications.
