Endress+Hauser Liquiphant M FTL50H Vibronic Point Level Switch

Description

The FTL50H is a point level switch from the Endress+Hauser Liquiphant M series, engineered for reliable liquid detection in hygienic applications. Its vibronic principle ensures maintenance-free operation, independent of liquid properties like conductivity or dielectric constant. Housed in a robust 316L stainless steel enclosure with a Tri-Clamp process connection, it is perfectly suited for the food, beverage, and pharmaceutical industries. The integrated FEL54 electronic insert provides a versatile DPDT relay output and supports a wide-range power supply for global compatibility.

FAQ

What is the main advantage of the wide-range power supply (19-253VAC/19-55VDC)?

This feature offers maximum flexibility, allowing the FTL50H to be integrated into virtually any control system worldwide without needing a specific power supply. It simplifies inventory and is ideal for plants with mixed AC and DC control voltages.

Can this FTL50H sensor be used for aggressive media?

The sensor's wetted parts, including the tuning fork and process connection, are made of 316L stainless steel. This material offers excellent resistance to a wide range of chemicals, making it suitable for many aggressive media found in food, beverage, and chemical processing. However, always verify compatibility with your specific medium's concentration and temperature.

What does the DPDT relay output allow for?

A DPDT (Double Pole, Double Throw) relay provides two separate sets of contacts (two poles), each with a normally open (NO) and normally closed (NC) connection. This allows you to control two independent circuits simultaneously, for example, activating a warning light and sending a signal to a PLC with the same level switch.
