Endress+Hauser FTL31 Series Level Switch, 70°C Maximum Operating Temperature, 25 Bar Maximum Pressure - FTL31-AA4U3BAWSJ
This level switch is a vibration-based sensor designed to detect material levels in industrial process systems. It operates across a wide ambient temperature range and connects to remote monitoring via an extended cable, making it suitable for installations where continuous mechanical contact is undesirable. The device is intended for non-hazardous zones and incorporates a polymer housing for chemical compatibility.
Features and Benefits:
• Operates reliably from -40°C to 70°C to cover extreme conditions
• Withstands process pressures up to 10 bar to 25 bar for diverse systems
• Uses just 15 mA current consumption to reduce power draw on loops
• Supplied with 1000m cable to enable distant mounting and control-room runs
• Threaded mount design for straightforward installation into standard ports
• Polymer housing material resists corrosion and simplifies maintenance
• Withstands process pressures up to 10 bar to 25 bar for diverse systems
• Uses just 15 mA current consumption to reduce power draw on loops
• Supplied with 1000m cable to enable distant mounting and control-room runs
• Threaded mount design for straightforward installation into standard ports
• Polymer housing material resists corrosion and simplifies maintenance
Applications
• Suitable for monitoring bulk solids in silos and hoppers
• Ideal for liquid level detection in tanks with moderate pressure
• Used with remote control rooms where long cable runs are required
• Can be used for point-level switching in pump protection schemes
• Suitable for non-explosive industrial process vessels

What type of enclosure does it have for corrosive environments?
The unit is enclosed in a polybutylene terephthalate casing that provides chemical resistance and reduces the need for metallic corrosion protection.
How is the sensor mounted into process equipment?
It uses a threaded mounting interface allowing direct insertion into standard tapped ports for secure mechanical attachment.
Is the device suitable for classified hazardous areas?
No, it is not certificated for hazardous-area use and should only be installed in non-hazardous locations.
What electrical loading should be planned for in system design?
The sensor draws a low operating current of 15 mA, which should be accounted for in loop power budgets and input circuits.
Does the product meet any conformity marking for European markets?
It carries a CE marking indicating conformity with relevant UK and European directives for marketed electrical apparatus.
