Endress+Hauser introduces new level switches for liquids
Liquiphant FTL31 and FTL33 switches handle difficult conditions that other sensors cannot.

Switches for all of your needs
The FTL31 and FTL33 are both able to work in areas where measuring principles are not suitable due to conductivity, build-up, turbulence, flow conditions or air bubbles. They have proven to be great replacements for float switches or conductive, capacitance and optical sensors in the food and beverage, pharmaceutical and other industries.
Working in extreme conditions
The switches can be installed in both vertical and horizontal positions within vessels, pipes or tanks.
The FTL31 has a stainless steel housing and works in process temperatures up to 302°F and pressure up to 580 psi. It is unaffected by changes in ambient temperatures and is mainly used for overfill prevention or pump dry-run protections in filter systems and cooling vessels.
THe FTL33 meets food industry requirements and is designed to work where CIP and SIP cleaning takes place.
Additional features
Both sensors come with stainless steel housing and can have either a three-wire DC-PNP output or two-wire ac/dc output when it reaches the switching point.
Each device has two operating modes:
Maximum safety mode: the switch is kept closed as long as the liquid level is below the fork, as in overfill prevention applications.
Minimum safety mode: the switch is kept closed as long as the fork is immersed in liquid. This is useful for things such as dry-run protection for pumps
