LFT3013 Ceramic Piezoresistive Level Transmitter
PRODUCT FEATURES
Description
The LFT3013 is a fully sealed,submersible level transmitter that uses a corrosion-resistant ceramic piezoresistivepressure sensor.The probe,immersed in the measured medium,is made of 316L stainless steel or titanium alloy.Thevented cable is made of PTFE or polyurethane,making it ideal for:Sewage;Seawater;Other demanding liquid levelmeasurement applications.
The housing is fully welded,and all connection points(housing,cable,etc.)are sealed with multi-layer protection.Internal components are potted to ensure long service life and reliable performance in:Chemical industry;Watertreatment;Environmental protection;Pharmaceuticals;Industrial process control.
