Endress+Hauser FTW325 Series Level Switch, 60°C Maximum Operating Temperature, Polypropylene Housing Material - FTW325-A2B1A
This level switch is a compact sensor designed to detect liquid levels in industrial control systems. It operates across a broad temperature range and is suited to installations where a rugged, chemically resistant enclosure and rail-mounted mounting are required. The device is built for low-voltage switching and integration into hazardous-area installations where recognised approvals are necessary.
Features and Benefits:
• Polypropylene housing provides chemical resistance and low weight
• DIN rail mounting enables fast, tool-free panel installation
• 1m cable delivers flexible connection to control equipment
• 40V DC maximum rating supports low-voltage control circuits
• 2 A switching capacity allows direct actuation of small relays
• -20 to 60°C temperature range permits varied ambient operation
• DIN rail mounting enables fast, tool-free panel installation
• 1m cable delivers flexible connection to control equipment
• 40V DC maximum rating supports low-voltage control circuits
• 2 A switching capacity allows direct actuation of small relays
• -20 to 60°C temperature range permits varied ambient operation
Applications
• Suitable for liquid-level monitoring in chemical dosing panels
• Ideal for integration into control cabinets on production lines
• Used for sump-level detection in hazardous-area locations
• Can be used for pump control in small process skids
• Used with low-voltage safety circuits in measurement racks

What electrical limits should installers observe for safe operation?
Operate the sensor below its maximum voltages and currents
the device is rated to 30V AC and 40V DC with a peak switching current of 2 A to prevent contact damage.
Which certifications allow use in potentially explosive atmospheres?
It carries approvals for ATEX, CSA and FM, permitting selection for systems that require recognised hazardous-area certification.
How does the mounting style affect panel layout?
The DIN rail configuration permits compact grouping inside enclosures and simplifies replacement without panel rework.
What environmental temperatures can the unit withstand during service?
The switch is specified to function in ambient and media conditions from -20°C up to 60°C.
What material considerations affect chemical compatibility?
The exterior is made from polypropylene, offering resistance to a range of process fluids while providing electrical insulation.
